Words can not describe about how impressed I am with your breakdown of DLSS 3. You make it easy to understand complex technologies. I should probably donate to you.
@@you2be839 well. It's a new frontier. People dunked on DLSS1 for a good long while. This would be great for improving experience at high fps if we can get the vsync and game capping better controlled. I would love a 50 actual boost to 100fps locked. The game would play smoothly and not turn my computer into a toaster for 3rd person action games, for instance. Obviously not applicable for eSports, but those games are rarely dependent on modern tech anyway, outside of Reflex.
No wonder Alex hasn't had time to cover Quake ray tracing yet. There's a tremendous amount of work done here and some eye opening stuff on this new technology's strengths and limitations. Thanks so much, Alex!
Thanks Alex! Great video. The example showing a moire pattern from DLSS upscaling when there is a larger time gap between frames is really interesting - makes a lot of sense, but not something I had considered before. And I really appreciated the discussion on how to think about frame generation quality and the scenarios where it can be noticeable, as well as the conversation about vsync and input latency.
Was expecting a slowed down, here's what the AI frames look like, kind of deal. What I instead learned is that you're the expert for a reason. Very cool, very informative. Excellent video.
It might be possible to separate the fake frames from the real frames. You could then play a video with only the real frames next to a video with only the fake frames. Could be an interesting way to visualise its effectiveness in different games
Incredible stuff. The quality of YT coverage of things like this is in an amazing place - hugely in awe of the things you have noticed here, as well as figuring out what's causing them! DF's coverage of the software/user experience side of things combined with GN's hardware insight has been so fascinating and useful.
This video is of pure gold: from basic explanation of how DLSS3 through commonly asked questions and even having nice examples of when and how DLSS and other AI-generated frames simply don't work. Amazing job!
i cant even imagine how much time and effort does it take to make a video with this quality alone👏 its a busy couple of weeks for sure (uncharted pc , a plague tale , cod mw2 ,scorn , Gotham knights, bayonetta 3) i hope all DF team are doing ok
Such a great video, as always! I agree it's really hard to judge the quality of DLSS 3 atm. Often it looks super impressive, but then in F1 2022 you can see a similar effect to what you show with spider-man's legs. Hard to describe, but that shimmering / flickering can be annoying once you see it.
The latency analysis, as everyone has pointed out, is mind-blowing and eye-opening. This is literally paper-worthy analysis. Thank you DF team and especially Alex, for giving us an insight into the knowledge that you guys have.
Even slowed down from 120fps -> 60fps I'm having an extremely hard time seeing these Frame Generation artifacts. The vsync issues while panning in flight sim were quite obvious, but not much else beyond that. I'm thinking this tech is going to be absolutely fine for everyday use and I'm excited to see it come down to some more affordable cards.
Think of the spiderman example, it's not so much that you clearly see the artefacts, but you might notice weird flickering, or blurring. Or in the case of low framerate sense the input latency. But still it's quite impressive
as long as people pay for the 4080 and 4090s affordable will mean 800 - 1000$. Maybe this is the the decade of consoles and they will become more relevant and a better option(for gaming) than pcs sooner or later.
@@johnjonson6377 There are affordable alternatives that provide console like performance such as the RX 6700 that can be bought new for 350€ or less, hopefully it will remain true for the next gen 7700 post launch so we get decent raytracing at a discount
God damn this was incredible work. I fully expect every other youtuber to link this video when talking about DLSS 3, not worth to even bother covering it when there's such a masterpiece out there already.
Alex you’ve blown this out of the water and gone absolutely next level. Brilliant video. Informative and an absolute pleasure to watch. Keep doing what you do!
17:15 the high visibility of these flickering artifacts around spidey's legs could also be explained by the contrast between the suit and the extremely bright sun reflection. On the other hand the fairly large reconstruction of the brick wall texture is a different beast altogether - the spot is filled with pixels very similar to the surrounding texture, hence you can't see it during 120 fps gameplay. It's the difference between picking an average color to fill a hole and drawing a new outline for important geometry moving against a contrasting background.
DLSS 3 Frame Generation is being modded to work on Turing and Ampere Cards..! Although there are some FPS instability issues and concerns about NVIDIA Locking it through Driver Updates.
NVIDIA will probably allow the frame generation on Ampere Cards so that it can act as a selling proposition for these bulky Lovelace cards. Still.. if one can get atleast a gain of stable 10 FPS .. it's a huge difference ... just like 522.25 Driver's DX12 FPS Gains.
Your work is so important, nobody does it like digital foundry. I only wish it was seen by more people, but these things are technical and complicated so the watching demographic is unfortunately a small subsection of gamers.
Unfortunately most gamers are less educated and less informed kids and they are not looking for good quality technical content. Channels that bait fanboys with toxic content get much more attention and views from gamers. it's a shame DF videos don't get nearly as many views they deserve.
01:56 You can try to use some losless Codecs to record like UTVideo. Most of them are CPU only and Multithreaded. They have almost no performance impact (since almost no compression is happening), but require a lot of disk space since (at 1080P) they produce 4-7 GB/min. I used this method for almost 8 years for my YT Channel and the resulting quality (at the time) was always A LOT higher than NVenc. The mentioned "frame dropping" should be a result of either the Nvidia Hardware or the current implementation in OBS. This problem is especially annoying if you stream to TH-cam via HLS which results in the exact frame dropping you described.
Not exactly. The issue comes from the fact that anything outside of HW encoding occurs non zero copy performance losses then, so it's actually somewhat unoptimal funnily enough.
You mentioned that the RTSS FPS cap does not reduce input latency. I think you will find that if you use the in-game FPS cap, it will. I don't know why but this tends to happen in most games. Battle(non)sense has covered this extensively
Hardware Unboxed found that DLSS3 frame generation heavily breaks dynamically moving HUD elements on screen, like player names in "F1 22" or POI markers in "Microsoft Flight Simulator". In those cases they come across as major issues and are extremely distracting. What sucks for nvidia is that they don't support DP2.0. So no 4K 240fps, although that would be the most viable target. at lower FPS it breaks apart a lot, at higher frame rates outside of the displays refresh range you need to contend with tearing... And once we see 4050 and 4060 cards, frame generation will make even less sense due to the lower framerates.
I love how Alex is channeling Richard Leadbetter in this video! Talking with his hands, the use of patented Leadbetter lingo, "Ok, so let's", "Yes, you are seeing that correctly", "with that being said", "Altogether I would say", "check this out", he's even got the Leadbetter cadence and inflection :)
LOVE IT !!! I love when Alex gets technical, actually whole DF team in hardware or software technicality "under the microscope", lots of knowledge with ig amount of great and usefull information !! Amazing, great job all ! Keep up the amazing work you're doing for gamers and enthusiasts !
The amount of effort put into the quality of information and the video is mind blowing. Thank you Alex for always feeding us nerds with everything we look for when new tech launches 😍
🤯 I'm going to have to watch this a few times to grasp all the nuances of DLSS 3. Thanks for all the hard work Alex and DF put into this detailed early look into this very neat technology.
DLSS wasn't that great when it was first introduced, but it's improved dramatically over time. It'll be interesting to see DLSS 3 Frame Generation improve over time as well.
@@ahmeti.7595 Sadly that means Nvidia will focus less on the actual performance of the GPU as we have already seen with RTX 20, 30 and 40 series by now.
@@yomamasohot6411 what do you mean? They have made the 4090 nearly double the efficiency of 3090 ti . Check hardware unboxed video where they cap a game to 90 fps. The 3090 to draws 416W whereas the 4090 draws 215W
As impressive as these techniques are on a technical level, DLSS really is a band-aid solution to compensate for display technology outpacing GPUs. Hoping that my 4090 means I can turn it off altogether and get 4k60 on modern titles.
@@yomamasohot6411 They've delivered on rasterized and ray tracing performance improvement over last generation as far as flagship vs flagship. The 4080 cards are embarrassing and quite misleading on their marketing on Nvidia's part.
As soon as I heard "strobing" I immediately thought of seizures. Strobing lights are often a cause of seizures though I'm not sure how much that'll effect DLSS 3. Blessedly it, and people, are fine. :)
Phenomenal work! Highlighting specific areas where DLSS 3 can falter is very useful for discussion, and helps to bridge the gap between the subjective (i.e. what we "notice" in the image) and the quantitative (what we can actually "measure"). I did have a question regarding screen-tearing, G-Sync and latency though. When using DLSS 3, would screen-tearing issues be resolved, and the latency penalty reduced, if you: 1. Enabled G-Sync in the control panel, 2. Left V-sync off in the control panel, 3. Capped FPS using an in-game limiter or RTSS, below the max refresh rate of your monitor? (e.g. 118 FPS in your case) My thinking here is the omission of forced control panel v-sync would remove an extra layer of latency, while an FPS cap would still keep you within the G-Sync window. Of course, I'm not sure if this also breaks normal G-Sync in the process?
I can't speak for DLSS3, but I know that using GSync while Vsync is Off results in tearing at the bottom of the screen, with or without a framerate limiter, even when remaining within the GSync window. The only way to eliminate tearing entirely is to enable Vsync. Without DLSS3, you'd want GSync + Vsync + Cap FPS around 3 frames below your refresh so that, like you correctly stated, you remain within the Gsync window and don't experience Vsync latency. But as Alex has demonstrated, that's not applicable with DLSS3.
Ah cool, thanks for the clarification. Even though Alex mentioned it in the video, I wasn't totally sure if V-Sync was always a prerequisite for G-sync to work, or if this only applied when DLSS 3 was active. I've never owned a G-sync monitor, so this is actually surprising to learn. On my freesync display, I usually just make sure the game is running in Borderless and freesync kicks in just fine.
@@WickedRibbon It applies to Freesync too. These techs alone are a big improvement over running with no sync, but they gotta be combined with Vsync to entirely eliminate it in every game use case.
23:08 If you look at the label on the bar "El Coyote" - its darker on the DLSS3 side just like DF mentions earlier in the video. Also, the place where bottles are on shelves looks darker. Same with the ceiling lamp in the middle where the brightness is different. This might reduce contrast in some scenes but probably unnoticeable otherwise. Also look at the Dart board? circle next to bartender - that area looks differently lit in DLSS3 vs traditional. However if you look at the middle seat where no one is sitting - the contrast is not lost w.r.t its surroundings. Brightness reduction is most apparent on the skull above the bar. DLSS3 needs work for sure.
DLSS 2 needs adaptive quality. Being able to set a target framerate just below the refresh rate and have it automatically adjust the DLSS quality to stay below this framerate would be very helpful. Heck even go into DLAA if needed
Really important thing to note: Keep in mind that if you have both G Sync and V Sync active and your FPS is at your monitors refresh rate you will have only V Sync active and that will increase your input latency pretty heavily. Yes, it is recommended to have both G Sync and V Sync active (for no tearing at all) as long as your FPS is below your monitors refresh rate (recommended to limit your FPS with RivaTuner). The reason why it's recommended is because while having G Sync active (below your monitors refresh rate) the downsides of V Sync's higher input latency are mitigated by G Sync (as long as you don't reach your monitors max refresh rate). In conclusion I wouldn't recommend having V Sync forced ON globally because it might negatively impact your experience in some games, especially competitive games that usually have higher FPS and can easily reach the max refresh rate of your monitor. What I personally do is activate V Sync on a game by game basis while having G Sync active for all games (since G Sync will not affect input latency in any way). And sometimes limiting my FPS slightly below my monitor refresh rate for a zero tearing and no additional input lag experience in cinematic games. PS: Regarding 31:00 in the video. Yes, Riva Tuner is enough to reduce the input latency *as long as you limit your FPS slightly below your monitors refresh rate* Ex.: Max refresh rate is 144Hz, I limit my FPS to 138 or 140 FPS.
I understand that this video's topic is slightly different but I wanted to drop this bit of information just to let someone ppl know that it's not the greatest idea to have V Sync forced ON globally and why.
@@musabmohammed8446 Yes, if you also have G-Sync or Free-Sync active and are limiting your FPS to slightly below your monitors max refresh rate. In fact you'll have no impact on input latency if you do this. Basically you'll have the same input latency with V-Sync on or off if you respect these conditions.
I'm pretty sure this will never work. If it ever fails to correctly predict the player's inputs at least 99.9% of the time(wich will always happen, since no matter how good the predictions, it can't be 100% accurate), then the output will look and feel terrible, with the camera movements overshooting what the players is asking, and then snapping back to where it should be on the next "real" frame.
I believe by capping the FPS in RTSS instead of within Cyberpunk you are raising the input lag beyond what it needs to be, this was shown by Battle-Nonsense before. If you have Nvidia Control Panel's V-Sync enabled, you must also cap your FPS in-game to just a few below your monitors refresh rate. IE: 144hz monitor = 141fps cap in game. Otherwise you will get terrible input by letting hit your monitors max refresh. I assume this is well known by now but I also think a lot of people are confused on how to best set up their games optimally. Also, turning on V-Sync in the control panel will raise input slightly but not enough to matter. But, you should be trying to attempt to use V-Sync in the control panel ON to get the smoothest possible gameplay. It's how you get the full experience of G-Sync. I set up all my games like this, for example on a 240hz monitor, it would look like this: G-Sync/V-Sync(Control Panel) = ON In-Game FPS Cap = 237 fps Reflex(if game has it) = Enabled but NOT Enabled +Boost That's really all you need to set pretty much every game like. You will have the smoothest experience with the least input lag. There are some exceptions for competitive games that require the best input lag and most FPS(say you're getting 400+ fps). In that case, you would just uncap the FPS and turn OFF V-Sync in the Nvidia control panel. NEVER turn on V-Sync in game!
Great video! One thing to note is that it's a bit visible that you're not looking exactly at the camera, but a bit above, reading a script off screen, which looks kind of awkward. But aside of that I'm impressed by how much effort you've put in the video! Cheers!
Absolutely exceptional coverage. You're doing a really great job showing and explaining all of these issues and possible concerns for gamers to worry about.
This video is great. I get that we somehow need to reconstruct the perfect conditions for DLSS 3 frame generation to provide benefit: Wanting to tune our graphics to such a level that we will be playing close but below your refresh rate, at least at 90fps, and be ready to sacrifice a 10ms of input latency. I'm really confused by which is the audience of this technology (even though it's intellectually very interesting). I would prefer to lower a bit the settings to play at the same frames with DLSS2 but no latency penalty.
Amazing video, the only thing I don't understand though is why you would turn on VSync at all anymore if the ultimate aim is to have settings heavy enough to stop the game from exceeding your monitors maximum refresh rate? The lower latency of VSync off is a win and if the aim is to never exceed the monitors refresh then you won't have tearing above say 120hz, so why even enable it? Thanks again for the amazing video.
You'll still exceed the refresh rate sometimes, and the VSYNC only comes into effect when you hit the 120 FPS mark. So you're choosing between having occasional periods of higher latency when you are at or above 120 FPS, or periods of tearing. The tearing would be more noticeable for me and I'd do the same as Alex, but it may depend on the game and the person.
@@jsVfPe3 True, the only reason I'd probably leave it off is the extra 5ms latency you gain back by having it off when even below 120hz, like you can see on Alex's graphs at 28:51 for example. I know it's a tiny gain but I'd probably only enable VSync for games where I know I'll be getting crazy high framerates about 120 such as CS:GO, etc. Most of the games I'd expect these crazy frames in won't have DLSS 3 anyway so I'd just use the in-game VSync toggle on a game per game basis.
@9:03 So why didn't NVidia just call it Frame Generation instead of mixing it with other DLSS? They should seperate the distinction. This is NVidia Frame Gen and this is DLSS 3 Upscalling. I know they seperate them in games but it should be seperated in the marketing to.
You can also lower the GPU power limit with Afterburner instead of fiddling with settings when the framerate is above max monitor refresh rate for DLSS 3. This way u can save some energy too.
Hey Df, Alex as always an insane detailed video and great explanations. At 18:00 you mentioned the lack of games with cycling animations especialy with 1.person games, but shouldnt the constant weapon bopping animation be a good indicator? Its as close to the cam as possible and its constantly cycling
Excellent work! Your approach of showing how things can be counter-intuitive, not claiming to know the definitive answers at the moment and to highlight how the methodologies and test cases you'll be using to test DLSS3 relate to the principles of DF image quality analysis is truly brilliant.
It would be interesting to see a recording with the "real" frames removed, only showing the AI-generated intermediary frames. Maybe then it would be easier to understand what kinds of artefacts it generates.
In addition to enabling gsync and vsync, you should limit your frames under your monitor's refresh rate. That way you won't be subjected to the vsync delay.
@@Lackesis I'm more so trying to explain to anyone who happens to read this that while gsync+vsync is the correct thing to do, you need to use a frame cap under the refresh rate. If you use vsync as the limiter, you are not using gsync, rather you are fully vsynced and will get to enjoy the vsync delay in it's full glory.
@@unawarebot2529 There is some weird behavior going on, because Nvidia changed how vsync works recently so that turning on vsync+gsync in the nvidia control panel automatically caps your framerate below your refresh rate (for my 240hz monitor, turning on vsync with gsync caps my frames at 225), but it seems like it doesn't work properly with DLSS 3. Not sure what's going on there, might be part of why Nvidia said that Vsync isnt working with DLSS 3 currently.
But then you get uneven frame pacing, that makes the game look significantly more juddery and less smooth, that's why dropping to 59 fps while targeting 60 makes such a big difference
@@autodidact7127 it's the huge issue and a deal-breaker for him. He'll stick to DLSS2 and will get superior IQ and easy better latency and still good enough FPS. How about you? @Auto didact is it the huge issue and a deal-breaker for you. Will you stick to DLSS2 and get superior IQ and easy better latency and still good enough FPS?
Limiting FPS can be done in more ways, with software like MSI Afterburner you can lower power consumption. You can even underclock and undervolt the GPU for less performance to hit your let say below 120FPS. Another option would be to run the game in 5K,6K,8K to lower the FPS amount to not tear and add input latency. I would say the lower power consumption option would be the fastest one, cause it is just a sliding bar you can do in seconds. You can make 5 profile settings and just change it on the fly with hotkeys. 60% Power profile 70% Power profile 80% Power profile 100% Power profile 110% Power profile
This is incredible. I can't begin to fathom the amount of effort that must have gone into both researching the data and making it presentable to the general (admitedly somewhat enthusiast) public.
The massive v sync latency issue even with a frame cap when reaching the monitor’s refresh rate is a crucial issue that needs to be resolved! Especially with a powerful card like the 4090
Great in depth analysis. But I can not understand how anyone still recommend to enable VSYNC. VSYNC always has and always will be introducing terrible output latency, and with HFR screens tearing is basically invisible when playing in realtime. And then he describes how to turn up your settings to reduce framerate below the screens limit and reduce latency again (which only works on a VRR screen anyway). Well then you do not have to enable VSYNC in the first place, VSYNC on or off makes no difference (on a VRR screen) as long as you stay below the screens refreshrate. And for the "accidental" too fast frame, you certainly notice the sudden latency stutter from VSYNC more then the tearing that you may not even see depending on where it occurs and how fast your actual refreshrate and framerate is. The best way of course would be if you can use an ingame framerate limiter, that can prevent you from going into the VSYNC range with no additional latency (often actually less latency) at all. But VSYNC is really a tool from the past that should not be used anymore on modern hardware.
It’s brand new tech so it’s definitely going to be a few months before they really optimise it, and iron out the bugs. Got to say, the 4080 is the best GPU I have ever had. The amount of performance uplift even over my 3080 is insane, and it runs 10 degrees + cooler than my old 3080 ever did on most games. Haven’t even seen it go above 62 degrees on Plague Tale Requiem maxed out at 4K, or go above 310W of power.
15:12 Our brains are incredibly good at compressing down visual information into digestible chunks. In my opinion, if it's not noticeable in play or can't be felt then it doesn't matter. This isn't the first trick games have used to trick our brain into thinking something looks better than it is (eg. parallax to give depth) and if it's successful at its trickery then in my opinion it's essentially equivalent to native. I argue that, because unless a person would notice the differences in a clip with all native frames and one with generated frames then as a whole, both must be equivalent to that person. But definitely issues with flickering and other artifacts should be heavily considered. I find flickering especially (of any kind) to be one of the worst kinds of visual fidelity issues. My eyes are always drawn to flickering and it really takes me out of the game. So super glad you took the time to go in depth on what kind of things DF should evaluate while still emphasizing how, as a whole, it's still an incredibly effective piece of technology.
tbh these stuff is getting more complicated each time they add a new technology. vrr and vsync/framerate limiters already caused some headaches, adding dlss3 just turns everything into a nightmare. even worse if we consider that all these settings (looking at globally enable vsync) might be needed to be applied on a per-game basis. it's crazy, we are al geeks here but just give us something that works out of the box! amazing video from DF as always
16:36 That's happens because our brain "cancels" error and noise of low frequencies when it "integrates" a bunch of frames, but not from higher frequencies. The persistence helps, but the difference of brightness is what rules.
Just for feedback's sake I will say that I found this video easy to follow, sometimes that isn't the case, the last DLSS 3 one was so jargony and so many numbers being thrown around I gave up on it. I was requiring to much of my concentration for very little info per segment. This video was better pace and more clearly laid out and so was no trouble to understand at all. Also the short clips with the Alex's talking head means I was listening more to what was being said and not being distracted by something in the footage (like a Cyberpunk car clipping through the road for example).
I can't even imagine a world without your channel. Thank you so much for all your efforts. I hope you made a revisit video for DLSS frame generation for the latest updates.
Bravo Alex, once again the most in-depth and informed analysis on a frame-rate increasing subject. I have to say that it looks good enough that most of those things I could only perceive with your guidance. It's apt that we get a frame generation tech on the same year AI image drawers began appearing in mainstream.
I wanted to thank you for this analysis Alex as I noticed the same panning issue in A Plague Tale: Requiem. Forcing Vsync in the Control Panel cleared up the issue. Top notch job!
There are a lot of compliments on this sophisticated review of DLSS. I agree DF is the best, but I'd like to go in another direction to help people... Product engineering is filled with very sophisticated and intricate problems. The folks that develope technologies are solving monumental problems delivering even the simplest technologies. They must balance all tradeoffs, and chart a course. I've been both an engineer and a customer and what I have generally seen is that the public does a lot of trivializing of what it takes to engineer a product. They can do the same thing with the business folks by for example treating a company like it was one person with one relationship with the world and other companies. The most disappointing cases I've seen have been with tech journalists. This is because of their outsized impact when they give wrong or trivialized information. So you have seen how hard dlss has been for DF. Hopefully you can extrapolate that to product engineering and businesses.
Impressive Dlss 3 analysis Alex, you did a really good job. Now i understand better how performs dlss 3 it's good to know how to use dlss 3 to not increase input latency too much. Good Job DF!
Look what I commented on your dlss 2 video over 2 years ago, I deserve a trophy!🏆 ”Frame rate upscaling could be (almost) latency free, if the Al had access to high framerate geometry, and it learned how to interpolate the rendered shading correctly. Let me predict: this will be the most important tech in a couple of years”
There is a way to show 120 fps footage on youtube at it's actual speed. It's to show the 60fps footage like you have been doing, then ask the user to speed up to 2x speed in the video player settings.
31:03 was not expecting this. Usually setting a frame rate cap 3-4 frames lower than your monitors refresh rate is enough to avoid the additional input lag caused by v-sync. I wonder why that's not the case here with DLSS 3. Maybe official v-sync support will make it behave like usual. Great and very thorough analysis as usual guys!
@@emile2330 I didn't think you did as long as you stayed bellow your monitors max refresh. I have certainly never noticed any with vsync off unless I go above my monitor refresh. If I do go above it then tearing is terrible, thus the frame cap. I thought this was the entire point of gsync, so you could disable vsync without tearing.
@@thecs9300 Nvidia control panel V-sync has to always be enabled when using G-sync. On top of that, preferably in Nvidia Control panel you should also use Ultra Low Latency mode.
@@thecs9300 I used to think that too, in my case there were some games where I didn't notice it and others where I did, there is a very good explanation of why you should use V-sync with G-sync on a page called Blurbusters, the correct way to use G-sync is by having V-sync enabled to avoid screen tearing and capping 3 or 4 fps below the max refresh rate to avoid the input lag caused by V-sync.

The methodology you explained shows you really know (and love) what you're doing. It's so enjoyable to to see such a thoughtful approach.
This is one of the best videos I’ve seen DF ever produce. Great job making this coherent, interesting, and usefully critical!
This video is of pure gold: from basic explanation of how DLSS3 through commonly asked questions and even having nice examples of when and how DLSS and other AI-generated frames simply don't work.
Amazing job!
I realized, that you fixed the "pumping" background (created by the auto-focus of your camera) in post (by masking it). Nice level of perfection :)
Yep :) thanks for noticing
i cant even imagine how much time and effort does it take to make a video with this quality alone👏
its a busy couple of weeks for sure (uncharted pc , a plague tale , cod mw2 ,scorn , Gotham knights, bayonetta 3) i hope all DF team are doing ok
After months of barely any developments over the summer, it's gonna be a non stop freight train now.
@@HeloisGevit yeah .. thats sucks
@@abdmo7575 Not for us!
@@HeloisGevit i dont have time to play so it kinda sucks for me too lol
probably ill just play uncharted and a plague tale
@@abdmo7575 I was thinking more of the quality analysis we'll be treated to by DF. As fun as playing the actual games.
Such a great video, as always! I agree it's really hard to judge the quality of DLSS 3 atm. Often it looks super impressive, but then in F1 2022 you can see a similar effect to what you show with spider-man's legs. Hard to describe, but that shimmering / flickering can be annoying once you see it.
It's only beggining too, DLSS 2 compared to 1 was a major leap and expecting a major improvement in the years to come
@@ramonandrajo6348 couldn’t get a card today?
3:18 Oh my god, his hands are gone 🤯Always thought that would be a real background ^^
I don't even own a PC, but love watching these technical videos, lots of information. Thanks
Same here. I have a crappy 4170 without gpu and do my gaming on ps5. But the tech insights covered on this channel are excellent
The latency analysis, as everyone has pointed out, is mind-blowing and eye-opening.
This is literally paper-worthy analysis.
Thank you DF team and especially Alex, for giving us an insight into the knowledge that you guys have.
Even slowed down from 120fps -> 60fps I'm having an extremely hard time seeing these Frame Generation artifacts. The vsync issues while panning in flight sim were quite obvious, but not much else beyond that. I'm thinking this tech is going to be absolutely fine for everyday use and I'm excited to see it come down to some more affordable cards.
Think of the spiderman example, it's not so much that you clearly see the artefacts, but you might notice weird flickering, or blurring. Or in the case of low framerate sense the input latency. But still it's quite impressive
as long as people pay for the 4080 and 4090s affordable will mean 800 - 1000$. Maybe this is the the decade of consoles and they will become more relevant and a better option(for gaming) than pcs sooner or later.
@@johnjonson6377 There are affordable alternatives that provide console like performance such as the RX 6700 that can be bought new for 350€ or less, hopefully it will remain true for the next gen 7700 post launch so we get decent raytracing at a discount
Alex is absolutely taking it to the next level with these videos.
Wow very good video Alex. Very in depth and explains the strengths and weaknesses of DLSS3 very well
Been super excited for this specific video. Thanks for all the work you do!
God damn this was incredible work. I fully expect every other youtuber to link this video when talking about DLSS 3, not worth to even bother covering it when there's such a masterpiece out there already.
Alex you’ve blown this out of the water and gone absolutely next level. Brilliant video. Informative and an absolute pleasure to watch. Keep doing what you do!
17:15 the high visibility of these flickering artifacts around spidey's legs could also be explained by the contrast between the suit and the extremely bright sun reflection. On the other hand the fairly large reconstruction of the brick wall texture is a different beast altogether - the spot is filled with pixels very similar to the surrounding texture, hence you can't see it during 120 fps gameplay.
It's the difference between picking an average color to fill a hole and drawing a new outline for important geometry moving against a contrasting background.
Bruh, these guys gotta be so GOOD at Where's Waldo
DLSS 3 Frame Generation is being modded to work on Turing and Ampere Cards..! Although there are some FPS instability issues and concerns about NVIDIA Locking it through Driver Updates.
It’s going to run like shit on those cards and be useless. They’re not fast enough to utilize it properly
NVIDIA will probably allow the frame generation on Ampere Cards so that it can act as a selling proposition for these bulky Lovelace cards. Still.. if one can get atleast a gain of stable 10 FPS .. it's a huge difference ... just like 522.25 Driver's DX12 FPS Gains.
What i like the most about DF videos is that it has a reverse clickbait titles, you always learn more than the title may lead you to watch.
Your work is so important, nobody does it like digital foundry. I only wish it was seen by more people, but these things are technical and complicated so the watching demographic is unfortunately a small subsection of gamers.
Unfortunately most gamers are less educated and less informed kids and they are not looking for good quality technical content. Channels that bait fanboys with toxic content get much more attention and views from gamers. it's a shame DF videos don't get nearly as many views they deserve.
01:56 You can try to use some losless Codecs to record like UTVideo. Most of them are CPU only and Multithreaded. They have almost no performance impact (since almost no compression is happening), but require a lot of disk space since (at 1080P) they produce 4-7 GB/min. I used this method for almost 8 years for my YT Channel and the resulting quality (at the time) was always A LOT higher than NVenc. The mentioned "frame dropping" should be a result of either the Nvidia Hardware or the current implementation in OBS. This problem is especially annoying if you stream to TH-cam via HLS which results in the exact frame dropping you described.
Not exactly. The issue comes from the fact that anything outside of HW encoding occurs non zero copy performance losses then, so it's actually somewhat unoptimal funnily enough.
Even if you have higher quality recording, TH-cam will compress it.
Compression will still be a thing and if weve seen anything its that cpus cant keep up with the 4090 already.
wich recording software are you using ? i've tried many but most of them doesn't support external codecs
@@Daburademo OBS supports ffvhuff for example.
That's what I personally use for recording at barely any performance loss.
You mentioned that the RTSS FPS cap does not reduce input latency. I think you will find that if you use the in-game FPS cap, it will. I don't know why but this tends to happen in most games. Battle(non)sense has covered this extensively
no, it's the other way around, and battle nonsense states this in a Witcher 3 comparison video I watched just last week
I think external vs internal framerate limiter might be interesting to look at regarding input lag with dlss 3.
this is undoubtedly the most advanced and relevant testing methodology developed for DLSS 3 so far. absolutely incredible work by Digital Foundry
40fps -> 80fps output in terms of frame times is actually half way between 30 and 60fps.
This imo is the sweet spot for frame gen
Hardware Unboxed found that DLSS3 frame generation heavily breaks dynamically moving HUD elements on screen, like player names in "F1 22" or POI markers in "Microsoft Flight Simulator". In those cases they come across as major issues and are extremely distracting. What sucks for nvidia is that they don't support DP2.0. So no 4K 240fps, although that would be the most viable target. at lower FPS it breaks apart a lot, at higher frame rates outside of the displays refresh range you need to contend with tearing... And once we see 4050 and 4060 cards, frame generation will make even less sense due to the lower framerates.
I love how Alex is channeling Richard Leadbetter in this video! Talking with his hands, the use of patented Leadbetter lingo, "Ok, so let's", "Yes, you are seeing that correctly", "with that being said", "Altogether I would say", "check this out", he's even got the Leadbetter cadence and inflection :)
LOVE IT !!! I love when Alex gets technical, actually whole DF team in hardware or software technicality "under the microscope", lots of knowledge with ig amount of great and usefull information !! Amazing, great job all ! Keep up the amazing work you're doing for gamers and enthusiasts !
Man I love nerding out with you guys! Thanks for the hard work.
The amount of effort put into the quality of information and the video is mind blowing. Thank you Alex for always feeding us nerds with everything we look for when new tech launches 😍
🤯 I'm going to have to watch this a few times to grasp all the nuances of DLSS 3. Thanks for all the hard work Alex and DF put into this detailed early look into this very neat technology.
Interesting stuff. Seeing the huge change in latency from exceeding the monitor's refresh rate was eye opening.
DLSS wasn't that great when it was first introduced, but it's improved dramatically over time. It'll be interesting to see DLSS 3 Frame Generation improve over time as well.
We should wait for DLSS 4 for improvements probably.
@@ahmeti.7595 Sadly that means Nvidia will focus less on the actual performance of the GPU as we have already seen with RTX 20, 30 and 40 series by now.
@@yomamasohot6411 what do you mean? They have made the 4090 nearly double the efficiency of 3090 ti . Check hardware unboxed video where they cap a game to 90 fps. The 3090 to draws 416W whereas the 4090 draws 215W
As impressive as these techniques are on a technical level, DLSS really is a band-aid solution to compensate for display technology outpacing GPUs. Hoping that my 4090 means I can turn it off altogether and get 4k60 on modern titles.
@@yomamasohot6411 They've delivered on rasterized and ray tracing performance improvement over last generation as far as flagship vs flagship. The 4080 cards are embarrassing and quite misleading on their marketing on Nvidia's part.
Outstanding effort made by DF covering this technical stuff. Kudos
As soon as I heard "strobing" I immediately thought of seizures. Strobing lights are often a cause of seizures though I'm not sure how much that'll effect DLSS 3. Blessedly it, and people, are fine. :)
Phenomenal work! Highlighting specific areas where DLSS 3 can falter is very useful for discussion, and helps to bridge the gap between the subjective (i.e. what we "notice" in the image) and the quantitative (what we can actually "measure").
I did have a question regarding screen-tearing, G-Sync and latency though. When using DLSS 3, would screen-tearing issues be resolved, and the latency penalty reduced, if you:
1. Enabled G-Sync in the control panel, 2. Left V-sync off in the control panel, 3. Capped FPS using an in-game limiter or RTSS, below the max refresh rate of your monitor? (e.g. 118 FPS in your case)
My thinking here is the omission of forced control panel v-sync would remove an extra layer of latency, while an FPS cap would still keep you within the G-Sync window. Of course, I'm not sure if this also breaks normal G-Sync in the process?
I can't speak for DLSS3, but I know that using GSync while Vsync is Off results in tearing at the bottom of the screen, with or without a framerate limiter, even when remaining within the GSync window. The only way to eliminate tearing entirely is to enable Vsync. Without DLSS3, you'd want GSync + Vsync + Cap FPS around 3 frames below your refresh so that, like you correctly stated, you remain within the Gsync window and don't experience Vsync latency. But as Alex has demonstrated, that's not applicable with DLSS3.
Ah cool, thanks for the clarification. Even though Alex mentioned it in the video, I wasn't totally sure if V-Sync was always a prerequisite for G-sync to work, or if this only applied when DLSS 3 was active.
I've never owned a G-sync monitor, so this is actually surprising to learn. On my freesync display, I usually just make sure the game is running in Borderless and freesync kicks in just fine.
@@WickedRibbon It applies to Freesync too. These techs alone are a big improvement over running with no sync, but they gotta be combined with Vsync to entirely eliminate it in every game use case.
The work you guys do is so valuable, your attention to detail and refusal to compromise is honestly inspiring, thank you and well done!
23:08
If you look at the label on the bar "El Coyote" - its darker on the DLSS3 side just like DF mentions earlier in the video. Also, the place where bottles are on shelves looks darker. Same with the ceiling lamp in the middle where the brightness is different. This might reduce contrast in some scenes but probably unnoticeable otherwise.
Also look at the Dart board? circle next to bartender - that area looks differently lit in DLSS3 vs traditional. However if you look at the middle seat where no one is sitting - the contrast is not lost w.r.t its surroundings. Brightness reduction is most apparent on the skull above the bar.
DLSS3 needs work for sure.
DLSS 2 needs adaptive quality. Being able to set a target framerate just below the refresh rate and have it automatically adjust the DLSS quality to stay below this framerate would be very helpful. Heck even go into DLAA if needed
Really important thing to note:
Keep in mind that if you have both G Sync and V Sync active and your FPS is at your monitors refresh rate you will have only V Sync active and that will increase your input latency pretty heavily.
Yes, it is recommended to have both G Sync and V Sync active (for no tearing at all) as long as your FPS is below your monitors refresh rate (recommended to limit your FPS with RivaTuner). The reason why it's recommended is because while having G Sync active (below your monitors refresh rate) the downsides of V Sync's higher input latency are mitigated by G Sync (as long as you don't reach your monitors max refresh rate).
In conclusion I wouldn't recommend having V Sync forced ON globally because it might negatively impact your experience in some games, especially competitive games that usually have higher FPS and can easily reach the max refresh rate of your monitor.
What I personally do is activate V Sync on a game by game basis while having G Sync active for all games (since G Sync will not affect input latency in any way). And sometimes limiting my FPS slightly below my monitor refresh rate for a zero tearing and no additional input lag experience in cinematic games.
PS: Regarding 31:00 in the video.
Yes, Riva Tuner is enough to reduce the input latency *as long as you limit your FPS slightly below your monitors refresh rate*
Ex.: Max refresh rate is 144Hz, I limit my FPS to 138 or 140 FPS.
I understand that this video's topic is slightly different but I wanted to drop this bit of information just to let someone ppl know that it's not the greatest idea to have V Sync forced ON globally and why.
Does this reduce vsync input latency?
@@musabmohammed8446 Yes, if you also have G-Sync or Free-Sync active and are limiting your FPS to slightly below your monitors max refresh rate.
In fact you'll have no impact on input latency if you do this. Basically you'll have the same input latency with V-Sync on or off if you respect these conditions.
Thank you for clearing up any questions I had about the new architecture and DLSS.
Great video. I wonder how long it will be until we see frame prediction instead of interpolation at a similar quality in real time.
I'm pretty sure this will never work. If it ever fails to correctly predict the player's inputs at least 99.9% of the time(wich will always happen, since no matter how good the predictions, it can't be 100% accurate), then the output will look and feel terrible, with the camera movements overshooting what the players is asking, and then snapping back to where it should be on the next "real" frame.
Unless the game is reading your mind, I don't see how it could possibly do this accurately and consistently.
I believe by capping the FPS in RTSS instead of within Cyberpunk you are raising the input lag beyond what it needs to be, this was shown by Battle-Nonsense before. If you have Nvidia Control Panel's V-Sync enabled, you must also cap your FPS in-game to just a few below your monitors refresh rate. IE: 144hz monitor = 141fps cap in game. Otherwise you will get terrible input by letting hit your monitors max refresh. I assume this is well known by now but I also think a lot of people are confused on how to best set up their games optimally.
Also, turning on V-Sync in the control panel will raise input slightly but not enough to matter. But, you should be trying to attempt to use V-Sync in the control panel ON to get the smoothest possible gameplay. It's how you get the full experience of G-Sync.
I set up all my games like this, for example on a 240hz monitor, it would look like this:
G-Sync/V-Sync(Control Panel) = ON
In-Game FPS Cap = 237 fps
Reflex(if game has it) = Enabled but NOT Enabled +Boost
That's really all you need to set pretty much every game like. You will have the smoothest experience with the least input lag.
There are some exceptions for competitive games that require the best input lag and most FPS(say you're getting 400+ fps). In that case, you would just uncap the FPS and turn OFF V-Sync in the Nvidia control panel.
NEVER turn on V-Sync in game!
Regarding that DLSS3 Vsync question: What if you use just the Frame Limiter in the Control Panel and not Vsync?
yes exactly
Great video! One thing to note is that it's a bit visible that you're not looking exactly at the camera, but a bit above, reading a script off screen, which looks kind of awkward. But aside of that I'm impressed by how much effort you've put in the video! Cheers!
Absolutely exceptional coverage. You're doing a really great job showing and explaining all of these issues and possible concerns for gamers to worry about.
This video is great.
I get that we somehow need to reconstruct the perfect conditions for DLSS 3 frame generation to provide benefit: Wanting to tune our graphics to such a level that we will be playing close but below your refresh rate, at least at 90fps, and be ready to sacrifice a 10ms of input latency.
I'm really confused by which is the audience of this technology (even though it's intellectually very interesting).
I would prefer to lower a bit the settings to play at the same frames with DLSS2 but no latency penalty.
Amazing video, the only thing I don't understand though is why you would turn on VSync at all anymore if the ultimate aim is to have settings heavy enough to stop the game from exceeding your monitors maximum refresh rate? The lower latency of VSync off is a win and if the aim is to never exceed the monitors refresh then you won't have tearing above say 120hz, so why even enable it? Thanks again for the amazing video.
You'll still exceed the refresh rate sometimes, and the VSYNC only comes into effect when you hit the 120 FPS mark. So you're choosing between having occasional periods of higher latency when you are at or above 120 FPS, or periods of tearing. The tearing would be more noticeable for me and I'd do the same as Alex, but it may depend on the game and the person.
@@jsVfPe3 True, the only reason I'd probably leave it off is the extra 5ms latency you gain back by having it off when even below 120hz, like you can see on Alex's graphs at 28:51 for example. I know it's a tiny gain but I'd probably only enable VSync for games where I know I'll be getting crazy high framerates about 120 such as CS:GO, etc. Most of the games I'd expect these crazy frames in won't have DLSS 3 anyway so I'd just use the in-game VSync toggle on a game per game basis.
Really interesting analysis, wouldn't haven't noticed half of the artifacts if Alex didn't pointed them out.
Awsome job Alex.
@9:03 So why didn't NVidia just call it Frame Generation instead of mixing it with other DLSS? They should seperate the distinction. This is NVidia Frame Gen and this is DLSS 3 Upscalling. I know they seperate them in games but it should be seperated in the marketing to.
You can also lower the GPU power limit with Afterburner instead of fiddling with settings when the framerate is above max monitor refresh rate for DLSS 3. This way u can save some energy too.
good idea, frame limiter via RTSS will do the same trick though as gpu load goes down right?
@@speedtree without DLSS 3 yes. Frmerate limiting seems to conflict with DLSS 3 though, causing higher latency.
Hey Df, Alex as always an insane detailed video and great explanations.
At 18:00 you mentioned the lack of games with cycling animations especialy with 1.person games, but shouldnt the constant weapon bopping animation be a good indicator? Its as close to the cam as possible and its constantly cycling
that animation isn't fast enough, the movement across the screen has to be faster than that
No
the movement must be too slow, if that other 3rd person test case running animation didn't garner that. good news =]
Maybe it isn't fast enough?
Excellent work! Your approach of showing how things can be counter-intuitive, not claiming to know the definitive answers at the moment and to highlight how the methodologies and test cases you'll be using to test DLSS3 relate to the principles of DF image quality analysis is truly brilliant.
It would be interesting to see a recording with the "real" frames removed, only showing the AI-generated intermediary frames. Maybe then it would be easier to understand what kinds of artefacts it generates.
Can't wait for the FSR 3.0 analysis
In addition to enabling gsync and vsync, you should limit your frames under your monitor's refresh rate. That way you won't be subjected to the vsync delay.
We still don't know how DLSS3 works with FPS limiter, but i think we will find out soon enough.
@@Lackesis I'm more so trying to explain to anyone who happens to read this that while gsync+vsync is the correct thing to do, you need to use a frame cap under the refresh rate. If you use vsync as the limiter, you are not using gsync, rather you are fully vsynced and will get to enjoy the vsync delay in it's full glory.
@@unawarebot2529 There is some weird behavior going on, because Nvidia changed how vsync works recently so that turning on vsync+gsync in the nvidia control panel automatically caps your framerate below your refresh rate (for my 240hz monitor, turning on vsync with gsync caps my frames at 225), but it seems like it doesn't work properly with DLSS 3. Not sure what's going on there, might be part of why Nvidia said that Vsync isnt working with DLSS 3 currently.
But then you get uneven frame pacing, that makes the game look significantly more juddery and less smooth, that's why dropping to 59 fps while targeting 60 makes such a big difference
Now that's REAL tech stuff we expect from DF and Alex in particular. Extended inspection of scenarios with nearly-scientific precision.
The huge input latency is a deal breaker for me. I'll stick to DLSS2 and will get superior IQ and way better latency, and still good enough FPS.
yeah especially with an rtx 4090 :P
Is it a deal breaker for you? 🤠 Will you stick with DLSS 2 and get superior IQ and way better latency and still good enough fps? 🤠
All good it does incredible with anything so no worries lol
@@autodidact7127 it's the huge issue and a deal-breaker for him. He'll stick to DLSS2 and will get superior IQ and easy better latency and still good enough FPS. How about you?
@Auto didact is it the huge issue and a deal-breaker for you. Will you stick to DLSS2 and get superior IQ and easy better latency and still good enough FPS?
Thank you Alex. Very informative.
Another glorified Nvidia commercial from DF. Might as well work there.
Limiting FPS can be done in more ways, with software like MSI Afterburner you can lower power consumption.
You can even underclock and undervolt the GPU for less performance to hit your let say below 120FPS.
Another option would be to run the game in 5K,6K,8K to lower the FPS amount to not tear and add input latency.
I would say the lower power consumption option would be the fastest one, cause it is just a sliding bar you can do in seconds.
You can make 5 profile settings and just change it on the fly with hotkeys.
60% Power profile
70% Power profile
80% Power profile
100% Power profile
110% Power profile
Amazing coverage Alex! You obviously put a lot of hard work into your analysis. DF will always be one of my favorite channels.
This is incredible. I can't begin to fathom the amount of effort that must have gone into both researching the data and making it presentable to the general (admitedly somewhat enthusiast) public.
The massive v sync latency issue even with a frame cap when reaching the monitor’s refresh rate is a crucial issue that needs to be resolved! Especially with a powerful card like the 4090
Great in depth analysis.
But I can not understand how anyone still recommend to enable VSYNC. VSYNC always has and always will be introducing terrible output latency, and with HFR screens tearing is basically invisible when playing in realtime. And then he describes how to turn up your settings to reduce framerate below the screens limit and reduce latency again (which only works on a VRR screen anyway).
Well then you do not have to enable VSYNC in the first place, VSYNC on or off makes no difference (on a VRR screen) as long as you stay below the screens refreshrate.
And for the "accidental" too fast frame, you certainly notice the sudden latency stutter from VSYNC more then the tearing that you may not even see depending on where it occurs and how fast your actual refreshrate and framerate is.
The best way of course would be if you can use an ingame framerate limiter, that can prevent you from going into the VSYNC range with no additional latency (often actually less latency) at all.
But VSYNC is really a tool from the past that should not be used anymore on modern hardware.
It’s brand new tech so it’s definitely going to be a few months before they really optimise it, and iron out the bugs.
Got to say, the 4080 is the best GPU I have ever had. The amount of performance uplift even over my 3080 is insane, and it runs 10 degrees + cooler than my old 3080 ever did on most games.
Haven’t even seen it go above 62 degrees on Plague Tale Requiem maxed out at 4K, or go above 310W of power.
Alex dropping analysis masterclasses once again. Regularly scheduled programming.
Given the nature of DLSS 3 and TH-cam limitations, this video is one of the hardest videos ever produced
15:12 Our brains are incredibly good at compressing down visual information into digestible chunks. In my opinion, if it's not noticeable in play or can't be felt then it doesn't matter. This isn't the first trick games have used to trick our brain into thinking something looks better than it is (eg. parallax to give depth) and if it's successful at its trickery then in my opinion it's essentially equivalent to native. I argue that, because unless a person would notice the differences in a clip with all native frames and one with generated frames then as a whole, both must be equivalent to that person.
But definitely issues with flickering and other artifacts should be heavily considered. I find flickering especially (of any kind) to be one of the worst kinds of visual fidelity issues. My eyes are always drawn to flickering and it really takes me out of the game. So super glad you took the time to go in depth on what kind of things DF should evaluate while still emphasizing how, as a whole, it's still an incredibly effective piece of technology.
Alex content that starts with Klepacki music is always great.
tbh these stuff is getting more complicated each time they add a new technology. vrr and vsync/framerate limiters already caused some headaches, adding dlss3 just turns everything into a nightmare. even worse if we consider that all these settings (looking at globally enable vsync) might be needed to be applied on a per-game basis. it's crazy, we are al geeks here but just give us something that works out of the box!
amazing video from DF as always
16:36 That's happens because our brain "cancels" error and noise of low frequencies when it "integrates" a bunch of frames, but not from higher frequencies. The persistence helps, but the difference of brightness is what rules.
Just for feedback's sake I will say that I found this video easy to follow, sometimes that isn't the case, the last DLSS 3 one was so jargony and so many numbers being thrown around I gave up on it. I was requiring to much of my concentration for very little info per segment. This video was better pace and more clearly laid out and so was no trouble to understand at all.
Also the short clips with the Alex's talking head means I was listening more to what was being said and not being distracted by something in the footage (like a Cyberpunk car clipping through the road for example).
ending amazed me. 100 with RT vs 90 without. blew me away Alex i was doubting DLSS 3 there for a moment
I can't even imagine a world without your channel. Thank you so much for all your efforts. I hope you made a revisit video for DLSS frame generation for the latest updates.
Bravo Alex, once again the most in-depth and informed analysis on a frame-rate increasing subject. I have to say that it looks good enough that most of those things I could only perceive with your guidance. It's apt that we get a frame generation tech on the same year AI image drawers began appearing in mainstream.
Wow, that was a lot of information! Kudos to DF und auf Wiedersehen!
I wanted to thank you for this analysis Alex as I noticed the same panning issue in A Plague Tale: Requiem. Forcing Vsync in the Control Panel cleared up the issue. Top notch job!
This analysis is really incredible. Such a great way to learn about this technology.
At 26:58, Alex's hair was flattened by DLSS3 intermediate frames. This artefact is not noticeable locally. :)
There are a lot of compliments on this sophisticated review of DLSS. I agree DF is the best, but I'd like to go in another direction to help people...
Product engineering is filled with very sophisticated and intricate problems. The folks that develope technologies are solving monumental problems delivering even the simplest technologies. They must balance all tradeoffs, and chart a course. I've been both an engineer and a customer and what I have generally seen is that the public does a lot of trivializing of what it takes to engineer a product. They can do the same thing with the business folks by for example treating a company like it was one person with one relationship with the world and other companies.
The most disappointing cases I've seen have been with tech journalists. This is because of their outsized impact when they give wrong or trivialized information.
So you have seen how hard dlss has been for DF. Hopefully you can extrapolate that to product engineering and businesses.
Impressive Dlss 3 analysis Alex, you did a really good job. Now i understand better how performs dlss 3 it's good to know how to use dlss 3 to not increase input latency too much. Good Job DF!
Look what I commented on your dlss 2 video over 2 years ago, I deserve a trophy!🏆
”Frame rate upscaling could be (almost) latency free, if the Al had access to high framerate geometry, and it learned how to interpolate the rendered shading correctly.
Let me predict: this will be the most important tech in a couple of years”
Great video as always Alex! I love how you not just show examples but also explain the reasoning behind them. Very interesting to watch for sure!
There is a way to show 120 fps footage on youtube at it's actual speed. It's to show the 60fps footage like you have been doing, then ask the user to speed up to 2x speed in the video player settings.
Absolutely brilliant job covering the different image quality test scenarios.
31:03 was not expecting this. Usually setting a frame rate cap 3-4 frames lower than your monitors refresh rate is enough to avoid the additional input lag caused by v-sync. I wonder why that's not the case here with DLSS 3. Maybe official v-sync support will make it behave like usual. Great and very thorough analysis as usual guys!
He still had vsync enabled in this case which confuses me
@@thecs9300 V-sync needs to be enabled if you want to avoid screen tearing, even if you have a G-sync monitor
@@emile2330 I didn't think you did as long as you stayed bellow your monitors max refresh. I have certainly never noticed any with vsync off unless I go above my monitor refresh. If I do go above it then tearing is terrible, thus the frame cap.
I thought this was the entire point of gsync, so you could disable vsync without tearing.
@@thecs9300 Nvidia control panel V-sync has to always be enabled when using G-sync. On top of that, preferably in Nvidia Control panel you should also use Ultra Low Latency mode.
@@thecs9300 I used to think that too, in my case there were some games where I didn't notice it and others where I did, there is a very good explanation of why you should use V-sync with G-sync on a page called Blurbusters, the correct way to use G-sync is by having V-sync enabled to avoid screen tearing and capping 3 or 4 fps below the max refresh rate to avoid the input lag caused by V-sync.
