BRB, off deleting Hazel!
😄
They say, there is always a bigger fish..
..and then Unreal just drops the Megalodon in the fishtank
Lmao
hahaha, contact me for a small discussion about a new project? (social proecjt haha)
I want to know more about model rendering and working with those constraints, or just buy/ a digital model of a humanoid.
Any help for me? Thanks :-)
;(
UE would play catch up with Hazel in the future. And we would look back at this day, when it all began.
Audio developer here: I'd like to chip in about the convolution reverb :).
The convolution reverb sounded great for all the reasons said in the video but there's a catch: it's ironically very static.
There are two common types of reverb: algorithmic and convolution.
Algorithmic reverb is relatively light on CPU, it's dynamic (the 'size' and frequency absorption of the environment can change over time) however, a good algorithmic reverb that can accurately simulate a real environment is very hard to create. They almost always rely on a complex network of delays (think of an audio echo effect), digital filters, modulation and feedback. Very fiddly stuff but powerful when it works. They can also be unstable due to the nature of feedback in the system.
Convolution reverb is often quite CPU intensive because it uses FFT (Fast Fourier Transform) techniques to efficiently convolve an input signal with an impulse response of a real environment (like a cave mentioned in the demo) and because of this, it's very hard to manipulate the impulse response in real time to make it dynamic. Convolution still requires a huge number of calculations on the audio samples because of the underlying DSP. You can interpolate between different convolution reverbs over time if the size or shape of the environment changes, but the problem with that is both impulses aren't 'aware' of each other and therefore don't interact how real sound waves would in that environment (resonances, phase cancellations at different frequencies, sound absorption etc). This is where algorithmic reverbs shine because everything in the network affects everything else in the signal path.
Unlike algorithmic reverb, convolution reverbs are very stable, predictable and they're INCREDIBLY realistic if the impulse was captured well. A good impulse response sounds/works great if the environment and character is static...these aren't. Getting a good impulse response of an environment is also very hard and involves a lot of expensive calibrated technology. When you do eventually capture an impulse response, you've captured that environment at that specific moment in time. That's it.
Fortunately most people don't care about stuff like this and convolution reverb works well in most cases. People will always prioritise visuals over sound for many understandable reasons, but you'll be surprised how a truly dynamic audio system can affect your experience in a game/film :).
I'm glad you mentioned this, I don't know anything about audio at this sort of level but this is what I thought when I first watched that part of the demo video. It sounded like they were saying they'd just captured the reverberation characteristics of one particular environment, which seems to be the opposite of everything they're doing with the graphical side of things.
That's a great point. I was looking to see if someone else noticed the convolution reverb. I am learning some audio development myself.
that's so true!
Yeah if it was not for the sound development in the battlefield series from Bad company 2 and up it would never have been so immersive. Sound design really is under appreciated. Have you heard what sony and Mark Cerny has done to the ps5's sound and audio capabilities?
Arcline, I found this interesting. Sound is so often dismissed, but can play a huge part in immersion. Could you give some input on what Sony are doing with their Tempest engine, they have gone big on sound in the PS5, would love to hear your thoughts on what they are doing.
I'm a 3D animator and I was like
Why am I even spending 10 hours ray tracing 5 seconds of footage.
Because this is the way.
@@aidenmiller3832 yeah maybe thats why games start to earn more the movies
I feel you man. 3D Artist aswell. But atleast all that wait is worth it. It may be subtle, but it's definitely better when rendered the way we do it. I'm just glad this tech is getting its foot into the gaming industry. And at real-time speeds. It's a cheat way of doing it. But it still looks 10x better than rasterization and fake lighting to fill areas.
If you don't mind me asking, what degree did you specifically get, and how's your salary? I know it's a public forum, but as someone who's interested in getting into the industry (or the animated film industry) I'm curious to see how you got to where you are. And what it's like.
Finally, someone who really understands how things are done reacting to the demo.
yeah, I was afraid it will be another clickbait thumbnail :D But very competent video!
I'm curious how Nanite works in details!
There was a guy on the LTT forums calling the game devs and Nvidia themselves dipshits because he thinks Nanite is the same thing as tessellation.
Yeah

I thought the exact same thing when he said that....
Was gonna ask for extended version too. I hope to get a bit more details about the tech, but I always enjoy these because he has a great and precise way of communicating.
Watching him go through the flying bit frame by frame is nice as that's how I'm gonna experience this when it's on my pc

I heard that this demo was also ran on RTX 2070 on PC. As in PS5 and Xbox are about RTX 2070 lvl in performance.
Personally can't wait for new GPUs from AMD and Nvidia as they supposedly go 50% up in performance. Except in raytracing they go up by 3-5x compared to first RTX cards.
@@heroninja1125 it was a joke brother
It's so refreshing to listen to someone with actual game engine knowledge talk about the possible algorithms/technology being used behind this demo. Unfortunately, most of the reaction videos out there are just journalist/TH-camrs with no technically know-how and while they are entertaining to watch they are saying so much nonsense and just repeating what others say. Loved the video. You need to do a few more of these. Maybe like a series? Can I suggest you do a video of the ps5 specs and how the new hardware is going to impact real-time graphics/physics/sounds? Thanks.
facts
I suggest you watch NX Gamer as well.
@@AnalogFoundry thanks! Great suggestion 👍
Second that!
ikr...and the cherno pauses the video whenever he has something to say, unlike every youtuber talking over the devs and then not understanding a single thing going on in the video. But like someone else here mentioned, NX Gamer has pretty good videos and insights as well when it comes to game engines and graphics.
I'm watching this like I have an idea what he is talking about.
lol, me.
🥱😎🤣🤣🤣🤣🤣🤣
*nods* *nods* i see...
I mean you can kinda understand it
😂
" i think they took all that Fortnite money and put it too good use"
I like how he said that soo much
😂😂😂😂😂👌👌👌👌👌
Yes them v bucks
I also got a kick out of that, though considering what they put their Fortnite team through during those early days as the game was exploding, I feel they should have sent a little more their way.
Cherno, yes, please upload your reactions and thoughts to the tecnical breakdown once it's out.
Also, could you make a video/series going through unreal engine 4's sourcecode and explain the rendering architecture and other interesting things?
Thanks for the Videos as always, very nice work!
Yes please, this could be so interesting
Bump
Yes please!
Honestly would love this
React to mark cerny PS5 deep dive pls
I think I speak for everybody: I want you to talk about the technical breakdown :D
No he will make another long video
Except if he do a 1 hour video
I wouldn't had a problem with a 1 hour breakdown cuz this guy knows what he's talking about but everyone else may have a different opinion
the thing is a little more advance but still using old code... the rest depend on what hardware it was design for....
Yes please and make it as long as necessary maybe edit it if you want as a second separate video
What’s absolutely crazy to me is that all of that can be broken down into 1’s and 0’s and beyond that we’ve taken rocks and other things out of the earth and organized them so precisely that they can interpret those on and off switches to create a new reality that is quickly becoming as incredible as our own. What a time to be alive
True. What a huge technology leap! It's like back in the old times! Changing ZXspec то nes then to megadrive and next to PS1! I honestly feel like we was stuck for many years, just developing useless computative power that can't be utilised, and now at least we go again, to the future!
"Audio is incredibly important" Nice to hear some appreciation for us audio folks lol, thanks bunches!
I'm not an audio guy. I'm just someone who plays games an' occasionally dabbles in making game assets. I don't..uh. I rarely appreciate good audio in a game. It's not really something I can point to, take a screenshot of and go 'You should see/hear this!". In addition, many of the outstanding audio things I *do* remember have been songs.. or interesting effects - Things like those radio stations in Far Cry 5. Those were awesome. But while I know I don't focus on it, I *do* know it's important... Without good audio a game is flat, or honestly.. flat wrong!
So... Thanks audio guy. You may not get the recognition you deserve... but you *do* deserve recognition. :)
I'd enjoy learning about the sound engineering field, as a pro musician.
Many years ago (like 30 or so) there was a game called "The day of the tentacle".
There was a scene were the hero was taken to some kind of vortex/portal, and was traveling through this for 20s.
The audio used at this scene was so amazing, immercive, that I still remember shivers I had. It was like in 1991...
Audio is a key.

@@nemiesis can you shortly outline why?
@ yes because he can write this, so he did
Frist of all Fortnite was in development for years it started on Unreal Engine 3(watch?v=2GSfjeYVpkQ -> trailer from 2011) and than moved to 4 and it wasn't a battleroyale game at all, but more like coop build to defend yourselves against the hordes of zombies or whatever(tbh I really liked the idea at that time and was definitely waiting), then they made a Battle Royal side project that appeared to be a worldwide hit. due to the brilliant building mechanic and great support.

@@brazwen "They're called minerals, Marie"
Lol
Reminds me of those BS "over-qualified" excuses in a job interview :D lol
Some of the details were already confirmed by some of Epic's graphics programmers on Twitter.
- There is compute shader software rasterization involved. Rendering such small triangles with hardware rasterization is slow, so they probably have a super optimized compute shader doing that. Maybe combined with visibility buffers instead of deferred rendering.
- They have virtual shadow maps with (roughly?) one texel per pixel that get also rendered with their micropolygon renderer. They use contact shadows/screen space raytracing to deal with the shadow mapping artifacts.
- Lumen uses a combination of screen space GI, signed distance fields and voxels.
- Also the demo is running with dynamic resolution scaling to 4k. It's rendered around 1440p most of the time
@@untseac I believe this demo doesn't use hardware RT... although RTX can be used to supplement what's in this demo. At least that's how I understood it.
@@ampluz according to the technical theories, FPS isn't an issue, it's the existing architecture and hardware, like input/output from running off an SSD or HDD drive when pixel streaming.
@@untseac The fact that there are so many different underlying systems that work in tandem to light the scene is one reason, raytracing is a unified approach to lighting that literally solves every aspect of lighting within a single algorithm/system.
Each underlying system in the traditional approach to lighting also has its own downsides that just aren't applicable to raytracing: shadow maps are susceptible to aliasing, acne and peter panning; the screen space raytraced contact shadows used to hide the peter panning is limited to screen space and has all of the downsides of screen space data; the screen space GI has those same downsides; distance fields tend to get pretty large and AFAIK are limited to static objects (the objects can move, but they can't change, so any sort of character or other dynamic model is not supported); voxels tend to get pretty expensive as you push more and more detail due to the ever increasing need of resolution to represent all that detail; and so much more that isn't even covered in that list DoomTobi posted.
The problem with raytracing is we're still not at the point where it's feasible enough to move everything over, not until the majority of users are able to comfortably run full raytracers (not the hybrid renderers NVIDIA has been pushing with most RTX titles, actual full raytracers, similar to Quake 2 RTX and Minecraft RTX) at least at 1080p 30 FPS, even on mid range systems and consoles. Until that happens, the industry will still continue investing in traditional tech, because it's just the safer option.
Plus, some of that investment also applies to raytracing, raytracers can still take advantage of Nanite and the improved animation and particle systems shown in this demo.
I'm a Game Design student and one of my professors recently revealed to us that he was on the team that did the animation for the character. Really interesting to get an insider's perspective about the work flow.
I remember ray tracing basic images back in the 90's on a pentium and for one basic picture it would render line by line and you'd have to go to sleep and wake up in the morning and sometimes it was still rendering.
damn!
and those were lower resolution, by prob quite a bit lol
Me too, used to do it on my dx2 66mhz, before pentium was a thing 😂
Lmao 😂
Just shows how far we've come
hey man, unrelated to the video, but I just found your channel again after like 8-9 years because of youtube recommendations. your tutorial on creating a 2D java game helped me pass my first programming course in college all those years ago! good to see you're still doing videos. subscribed!
These tech demos always look like they would make an interesting game with the right story behind them. Exploring caves and archeaological sites sounds like an interesting game
Need to make a Tomb Raider game out of it.
uncharted and tomb raider do just that
I would also like to see that one hour version of your reaction to this demo. And also to that point, I would love to see your reaction to Mark Cerny PS5 architecture deep dive. I was watching it like 3 times with open mouth - the PS5 memory management pipeline is magic. I'm also a software developer, but I develop serverside web applications. I'm curious to your opinion, since you're game engine developer.
I keep seeing articles downplaying the SSD in the PS5, that controller and channel bandwidth is definitely going to be key in providing a constant 5GB/s throughput while the XSX might only have 4 channels for its memory controller which might create some bottlenecks or even throttling. What I have read is some developers saying Kraken's compression for raw data is is only 20-30% while Microsoft's compression is around 50%, it's possible that Kraken will improve over time though. I don't think we'll see third party games take advantage of these until 2023 as a lot of games will be cross gen for a good year or 2.
@@Loundsify I also believe that PS5 memory management architecture will be a key advantage and not just the speed but the cache scrubbers as well.
The information about the Kraken is misleading though. While it's true that the compression will normally be about 20%-30% (which is actually quite impressive), you have to take into account that it's a general-purpose compression algorithm. Meaning it can compress not only the textures but the audio and the geometry as well. While Microsoft's compressor is purely optimized for textures. So obviously it works better on textures, but I'm not sure if it can be applied to anything else at all.
Only watched the first 3 minutes, but can already tell that this will be the best breakdown.

Kamil Karwacki I mostly care about maps. They seem important, but they’re boring. A good tutorial guy would go a long way.
I started as a coder on the demo scene in the late 80s, then moved on to web development for 25 years. Now I'm back learning game development from scratch. Good Lord how things have changed in 30 years!
I went and took a high quality photo of a Rock then when I tried to implement it in my game, I got sued by Dwayne Johnson.
Animator here: some thoughts about animation.
How high fidelity of uncompressed data will match the animation pipeline?
It's is great to see an improvement regarding animation in Unreal Engine 5. Contextual animation, motion warping and foot placement with IK is a good step forward.
Modern games character models (for example - Lara Croft from The Shadow of the Tomb Raider and Gerald The Witcher 3) have 70k to 120k triangles each. That amount of polygons is not easy to work with (in the context of rigging, skinning and animation.
Rigging and skinning (creating a skeleton that drives model and bounding it to mesh) is a pretty complex process on its own.
Zbrush can handle that many polygons while sculpting. Maya or 3ds max will collapse. Starting from Maya 2019 it's possible to turn on cached playback for animation. Another option is to get a model approximation (low poly) and then transfer animation to high poly mesh. However, all that is pretty complex and can cause undesirable results. Which leads to ending up with a lower quality product. All these issues may have a bigger impact if it's more that one character to animate in a scene.
The main character of that demo is stylised. It's clear from the opening scene. I will assume it's done to avoid the uncanny valley effect. Good example - Pixar or Disney movies.
In contrast, the environment in this demo is photorealistic. From ultra-high detailed models to photogrammetry.
That differentiation in styles makes her stand out from the main environment sometimes.
It will be interesting to see what approaches will be taken to adapt current standards in animation pipelines to match modern technology.

False leading title- there is actually content in this video, not just reaciton.
I'm happily disappointed.
The "infinite detail" tech strikes me as having even greater potential for VR.
In traditional games you rarely put your camera right up to an object - but that's common in VR. Being able to scale to extreme detail for very close objects being studied could make a world of difference.
I agree that I think it's just as important that this simplified workflow a ton. Building a scene with dynamic global illumination and no need for manually generating LODs means you take a lot of the gruntwork out of the task - leaving much more time to dedicate to the actual design and art. (or just a lower budget or more custom content).
I have no idea how they manage to do this real-time though. There either has to be some serious techno-wizardry at work here - or else there are big caveats not yet announced.
It's one thing to have the engine be capable of doing this, but doing it at a performance level that is good enough for games at high resolution... that seems like a quantum-leap forward.
Completely agree with you. My first thoughts were how massive this seems to be for VR moving forward. This literally solves a problem that has kept VR from truly becoming the mainstream. It's all definitely a quantum leap forward if what they show is as easy to implement as they make it appear. Games will now be interactive movies.
@@phoenixamaranth Well, I think the hardware is the primary obstacle to going full mainstream still (including the price of the hardware). Lower prices and really solid wireless transfer are "convenience" issues that have to be solved. But yes - these software developments, including stuff like variable rate shading and foveated rendering certainly makes it a lot more plausible to create really detailed environments in VR without requiring a monster-rig.
i want an engine that can run a massive rts game in real time world with total war sized wars and battles... but i want to play it like a mount and blade fps with a assassins creed style 3rd button masher free runner... you would have access to all 3 cameras rts style to move a bunch of people around a 3rd person button masher when your going stealth or working with a squad and for normies and the first person for the immersion and hard core awesomeness. you could use the rts camera by launching your trained hawk, a spell, and or an artifact... Modded kenshi has the foundation for truly amazing game world. if worlds are to small how do you fill it up with awesome stuff that doesn't require a lot of work. a world that functions without forcing anything down your throat it can be what you want it to be. i think an mmo with this stuff would be a living game world for the future. total war, mount and blade, kenshi, morrowind(factions, lore, secrets, crazy magic and... , assassins creed\ (souls ish think about it) fallout 1 and 2 in kenshi but on a bigger scale... i am so sick of the same games that we have been playing for the past 20 years. cod is lame bf is dead apex is fun, but apex is a stripped down ripoff ish free to play game lolololol. i really want some of my favorite games mechanics to work together in one game. your friends that like different types of games could all come together to fill specific roles. maybe some people mind craft build... others deal with rts defense other trade and smuggle while others can be in charge of getting the ai to grow crops or just get resources you could have guilds that do quests ever role a play can fill can also be filled by an npc it would help create a real economy supply and demand it would be a real reason for wars. maybe a solo player could grind forever and figure out a secret way to create a undead army and then creat his own faction and do whatever they want with it they wouldn't need to micro mange as munch... but you become a lich to do it. and you get a huge bounty or whatever... do this shit if you want to be rich. fuck vr we need real games

@@randomcatdude and consoles possibly overheating
The higher the texture quality, the higher the game size. Assuming this demo is 100gb, a game would be 100x that.
Considering how big a jump game sizes have experiences in the last decade, I think we all gotta brace for insane game sizes and hopefully technology allows ssds and hdds to become even cheaper lol.
Hmm it’s probably big. On the other hand. Mark Cerny explained that games often use a lot of copies of the same data to save reduce load times.
For example you have one model of a lightbulb in a game but you use it at 1000 different locations. You could save that data one time and then search for every time you need to use it. To prevent the HDD from spending time searching, devs often had the data multiple times on the HDD. So you let’s say you have a 100 buildings in your game then the game would load all the data for that building in a package und just search for the beginning of that package instead of searching for every bit of data needed for that building. Coming back to our lightbulb, that means there are 100 copies of that data. With the new architecture you can stream data much faster and the SSD has virtually no search times.
Thats a bold generalization, but I think this has the potential to slow down the size growth of games quite a bit.

@@eyeofthetiger7 Too many people focus on tflops, that is just one small part of what makes up a console. The end scene for example is almost certainly streaming assets straight off the SSD, The xbox would be twiddling it's tflops waiting for the data.

@@philterry3293 I am fairly certain he looked at Software Defined Flash for what he did. And compressing a drive for higher throughput is also not very new. I do it on my own system (bcachefs zlib).
Still nice he got it to work like this though.
@@philterry3293 lmao you're saying that as if the XSX SSD isn't insanely fast too. Likewise the XSX is actually a more competent machine, even if the SSD on the PS5 is breathtaking.
Given UE5 will run across all platforms your point is moot.
It's about time that we finally started taking advantage of SSDs.
3 years later and we still don't have a game that looks like this 🤔🧐

Mateusz Abramek i think they did a really god job managing ram. It just depends on your launch arguments. I made it possible that my Server with 16 active players run with only 800mb ram. Java will stay a ram beast, but as technology gets better and better, it isnt a huge deal anymore

I have the same soundcard, always red so people can hear me well
Haha, I just noticed when you pointed that out. It looks like a Scarlett Focusrite audio interface.
@@UltraNyan I think that means the audio is clipping. But hey, if it works and people can hear you better, then that's good. Sometimes a little bit of clipping doesn't hurt (in my opinion). You can always use stuff like a limiter to keep the perceived loudness but prevent the clipping.
@@evanmurray5032 The red light is actually a button that is red when phantom power is turned on (when the button is turned off the light turns off). Phantom power is used to supply additional power to a condenser mic.
Patrick Linihan Oh I see. I haven’t used an external power supply before. Now I understand what is meant by the red.
The fact that he doesn't know the PS5 specs but get can instantly tell that alot of data would need to be read from the SSD to make this a reality is really impressive lol.
One of the best videos I've seen. Do not worry about video time or dragging out explanations. Just do your thing and I'll watch. Great video one of my favorites
yeah at the end I wished it was an hour long lol
Well it's not like a mechanical HDD is going to be able to perform that level of I/O
"The fact that he doesn't know the PS5 specs but [...] can instantly tell that alot of data would need to be read from the SSD to make this a reality is really impressive"
I mean... that should be obvious
@@lennysmileyface Conventional SSD can't either, conventional SSD are not built specifically for throwing around 8K textures instantly, they are general purpose built for data. Sony patented the set up for PS5 which has 12 channel and 6 priority levels, the closest commercial drive to that has 8 channel and 2 priority levels, forget the cost 825GB, you'll lose an arm for 256GB of one of those things. Still would barely keep up, I listened to a tech talk about what Sony was doing and they literally capped the drive, they were actually going to go higher spec in the design but you know inquiring minds were like, the market won't have supplemental drives capable of being swapped out. Basically to remain compatible with community contemporary drives. Cerny did state they'll test conventional drives for those that can replace PS5 internal if the need arises. When you're advancements are held back by what's available in the current market and compatibility.
That's kinda obvious..
Definitely not the most impressive thing he was able to reason out in this video. It sounds like you didn't get most of it and you mentioned this because it was the only thing you were able to understand 😂
That's incredible, as you said.
There're actually no words to express of how huge it all is and how impressive it is.
Actually it's shit work. The body and world were rendered by two different systems. Easy to see.
@@prjndigo what do you even mean by "two different systems" xd? what you said sounds quite braindead
"No words... should have sent a poet"
Hey man, really cool video. Being in the industry for 15 years and it's one of the best vulgarization of game engine that I have seen so far. But still, I have 2 concerns regarding this demo. First, there is no AI so I am wondering what will be impact of AI on the engine performance, they have a tendency to eat up a lot of ms on the each frame. The other thing is vegetation, here it's all static rocks, but I would be curious to see how it look like in a FarCry kind of environment with thousand of trees moving with the wind.
But still this demo is impressive and is definitively setting the bar high for the next gen games. Also, coming from a producer, we cannot underestimate the value of not creating LOD or normal map out of the Z-Brush high rez model, is THE shit of this demo in my opinion.
It’s not just normal maps you’re not creating - you could technically simply not create maps anymore. Color can be painted at the vertex level, displacement is implicit, and things like subsurface scattering can be figured out of materials and volume so it literally changes the whole Texturing industry.
As for AI, you don’t need to worry it’s not gonna impact it negatively, if anything entirely the opposite as for all of this to happen they obvious need raytracing GPUs which are literally the bomb for artificial intelligence, the serious kind; so obviously it’ll run game AI more than ok.
Raytracing is a very important part of AI, being able to raytrace so much in real-time gives you (your enemies) a LOT of information which can be used for AI.
And the plants don’t really matter, as far as the engine is concerned they are just meshes, it will handle as many as you want as it will ultimately ONLY render x triangles per frame (where x is around 20 millions max), you could have even more plants than pixels and it wouldn’t make a difference, it just wouldn’t render every plant (which would end up being pixel small in order to al fit in the screen anyway, which is obviously something that won’t happen).
Nanite doesnt work with vegetation
Then there's me who's still trying to figure out whether I should delete the default cube or not in Blender.
Your wondering whether you should I'm wondering how.
Honestly: I took me almost 18 years to learn a new program (and since I am responding to you, the program I am referring to is Blender) after learning Anim8or in 2000, and even though I really wished to have learned to get the hang of Blender earlier, I have been able to do so much work in such a short amount of time (and there still is a huge amount of things to learn concerning Blender).
Personally, for me, the BlenderGuru tutorials helped me bigtime (I should really think about uploading some of my Blender work to my channel actually).
When you're french and you listen the ue5 demo:
The guy on the left: I'm technical director of graphics at epic games
The guy on the right: baguette baguette baguette, bonne appétit
I'm a Dutch now living since 17 years in Paris. Having a bit of a French accent in English (or Dutch in my case) is fine and actually adds some flavor as long as people can easily understand you and take it serious what you're saying.
@@richardbloemenkamp8532 yeah I'm just kidding, it's just that I heard a lot of French people working at epic games so each time I heard this accent it make me smile because I have the same one and I'm like "well, epic game definitly needs me to extend their french accents people" X)
French accent in kind of signature 😀
As a french in a company with lots of french people and for mostly clients; I can hear my colleagues talking in english all the times, and I can this guy did it very well , he got a weird accent on top of the "common" french accent.
I was like "The heck did he just say?", but jokes aside, some people understand the accent easily while some people don't and I often struggle to understand some accents and I even have problems understanding one of the accents of my native language but the point is that some of us can't help the fact that we struggle to understand some accents which in my experience, a lot of people fail to understand.
19:30 That sentence basically summarizes a huge majority of the low budget UE4 games.
Hitman absolution animations were really bad.
It is GREAT to see the technology having moved forward SO MUCH in my lifetime. Instead of rendering after hours, it can be done DYNAMICALLY.
Cherno what's up man, i remember myself learning to code java game with you ;) you had so little views like a thousand top and i was scared that you may not continue but you did man look at you growing in front of my eyes like that you deserve it ;)
This is the only take I've seen on this demo, trusted I haven't seen them all, that seems to have knowledge of what's going on in the background. It would be great to see you watch through Mark Cerny's breakdown of the PS5's architecture. I don't think I'm alone in this! Make it a Patreon tier and I'm there LOL
I agree, it would be awesome to see his reaction to "The Road to PS5".
8:37: "Right of the bat, this kind of reminds me of the uhhh... "
My brain: "... Uncharted"
I think you should do a reaction to the Mark Cerny PS5 deep dive Spec Reveal. It's called "Road To PS5"
Now the bigger picture..... Storage. Lmao we all know these models with that much detail will fill up a NVMe faster than a fly to poop. Its gonna be amazing when downloading the next AAA game takes up 500Gb on your drive.
Encoding algorithms do the compression in logarithmic graph. So it will be like 120-140 gb.
9:50 No what I'm seeing is my acid trip from 1971. Minus the duck footed flying turtles.
So according to Epic, this demo was running at around 1440p30. Far as I can tell from doing some research, not only should that level of detail be impossible even on current specs, but also the amount of processing necessary for GI, 1440p30 is a significant achievement. It reminds me of when NVIDIA debuted real-time ray tracing with their RTX GPU's and at first everyone thought it was amazing until they saw the framerates and resolutions, which at launch without optimizations, people were managing 1080p30 and mad that they couldn't do this at 4K60. But they missed the forest for the trees, the fact that we could do that at 1080p30 at all was a monumental thing given just how hardware intensive ray tracing is, and the fact that NVIDIA claimed this tech was originally thought to be at least 10 years away at the time. Epic claims this demo could run on an RTX 2070 Super. So pair this demo with a next-gen Ampere RTX GPU and its ray tracing performance gains, and you'll have golden performance in all these high quality facets.
EDIT: And consider the following: Lumen GI is real-time, just like Ray Traced Global Illumination, but with a slight delay as it calculates the new lighting and shadows. But since it doesn't require ray tracing or RT cores, you can effectively turn off Ray Traced Global Illumination in a game that uses Lumen and instead pair it with Ray Traced Reflections since Ray Traced Shadows are likely unnecessary. This is ridiculous performance cost savings on next-gen consoles, and saves you performance on PC as well since you can dedicate your RT cores other RT uses instead of GI or Shadows.
Nihren So exclusives 3 years from now will look like that and run even better?
RT cores aren't even used in the demo. That's the most impressive part.
@@tomhaswell6283 Right, it's all done without that. So you can dedicate your RT Cores or AMD's equivalent to something like RT Reflections to be used alongside Lumen and right there you have the full RT suite, but with RT only handling the reflections.
@@nihren2406 thanks man awesome insights!
i popped off hearing it wasnt done on rt cores, will my 1660 ti handle this? i wonder...
The ssd tech of the ps5 is a hardware implementation of Rad Game Tool's Oodle compression algorithm
Oh. That's genius.
feels like they've almost caught up with film industry (offline rendering I mean
Imagine how incredible a Red Faction game would be on this engine.
Red Faction 1 Remake please
now that they've got the global illumination thing going I wonder if the algorithm could be extended to work for sound - set the speed of sound and the characteristics of the surfaces. Then you could take an impulse response of the virtual space itself, using its exact geometry.
I wanted to know your thoughts on the PS5 specs and how they correlate with this demo!
"We don't need normal maps because we don't need that kind of cheap way..."
While watching this together, bump map puts its hand on normal map's shoulder: "this is it, buddy. Welcome to obseletion."
there's always still displacement maps...
Current data speeds and harddrive capacity is still cheering Normal Maps on. Nothing to worry about. Yet.
torilla tavataan
Normal maps will still be very commonly used in characters and other objects that have a high importance on the retopology I imagine a lot of the assets in the demo are using some kind of triplanar projection system to project detail normal maps on the assets for up close stuff when the detail gets so small to the point where increasing the polycount is just a waste
I'd be curious to know your thoughts on the PS5 architecture and how it might be facilitating all of this
Please make the follow up video that goes in depth with the technical details. I like your commentary style and analysis. Subscribed. Please keep up the great work.
The Cherno: "wow, very nice motion blur!"

This is from Wikipedia about PS5 Architecture and its SSD hard drive: "A custom SSD storage solution was designed for the PlayStation 5 to increase data input/output rates for fast loading times and larger bandwidth. This speed allows games to be more immersive and to support 8K resolution.[1] The base system has a 825 GB SSD connected via a 12-channel interface to the main system, achieving a 5.5 GB/s transfer rate uncompressed, and between 8 to 9 GB/s using compression with the Oodle Kraken protocol from RAD Game Tools. This atypical drive size was found to be optimal for the 12-channel pathway for the system rather than more typical 500 GB or 1 TB units. Direct storage for games is expandable through an NVM Express (NVMe) M.2 port, while additional storage can be made available through USB-compatible drives."
It sounds to me like this disk is like one big buffer/channel to VRAM area...
It's probably why they're able to stream 8k textures, the fact the textures of the rocks don't blurr when you get close to them says alot. I expect Sony's first party games to look extremely photo realistic.
"SSD hard drive" Would just be SSD. HDD is hard disk drive, while SSD is solid state drive.
Lol 5.5gb/s is not fast it the normal speed for m.2 drive samsung just made a 6.5gb/s
reading all the time to the SSD means that disks will be dead in less than 2 years of use... planned obsolescence
I don't care about "speeds", it feels like it's the old "PS2 stops reading discs" problem once again, it leaves a very cheap impression of the company in general
Gotta love the inspiration this gives to ANY developer out there! We're in the Golden Age - let's all get stuff done! :)
The most interesting question might be: How long will it take to see such level of fidelity in real games? I guess very soon. Sony studios will leverage that SSD tech from the get go, knowing their optimization stuff from the PS3/PS4, so I expect something very similar. Allegedly, a new Horizon game is in development. Hope this will be one of the launch titles that blows us away!
That's what I'm thinking. I can't remember which dev said it, but they said within a year you'd see how strong the PS5 is and not care about "TFLOPS".
GLegend360 isn’t the PS4 1.8 tflops and we got uncharted 4, god of war, horizon zero dawn, death stranding, tlou 2. What I’m saying is going from 1.8 to 10.3 tflops is gonna be amazing since Sony has talented studios. Just imagine how gta 6 is gonna look on both the ps5 and Xbox seX when rdr2 already looks photorealistic at times on a launch PS4
Wow this guy got the PS5 architecture by looking this demo... maybe he needs to look it deepley to teach us the diference between the PS5 and Series X
It's really not hard to make educated guesses when you know what exactly is happening behind the scenes. With the amount of data the engine is having to move around, to use some form of raw geometry data and 8K textures in the project, the system must be loading in data from an SSD, likely in a custom configuration to increase transfer speeds and reduce latency as much as possible.
@@jcm2606 We already know the PS5 is doing exactly that.
Dude I've got so much respect for you. This is truly the GOLD standard of TH-cam content.
After pc gaming for 25 years, looks like the day I've waited for has arrived. That's a long wait, people saying "oh no, 1TB games" is like complaining the safe you have is too small for all the gold you just found in your back yard.
"Sound field rendering for spacialized audio" is a huge step in game Audio. I would think is = similar to how they use Spherical or Cube maps for Reflections that update depending on placement of objects and the location of the character. RT Audio will definitely be one of the last in a games RT budget since Visuals come first for most. Focus on the GI, Reflections, Shadows for your RT Budget and stick with these cool methods like impulse responses and this "sound field spacialized rendering" for now since it sounds pretty damn amazing. Valves HRTF and forms of Ray Traced Audio do sound fucking amazing though. Just being able to see all these methods that were only used in 3D Software that took minutes, hours, or days for a single frame that is now realtime is something I didnt expect that soon. I know that resolution, the number of bounces, the noise filtering methods, light probes for approximation, and all the other types of new itterations/methods are definitely allowing for that gigantic step in photo-realism we used to dream about. Real-time RT is definitely one of those huge milestone in the progression of 3D environments. I cant wait for it to become so efficient that RT is the new norm for Visuals and it starts being used for other things like AUDIO! but for now I Global Illumination and AO are definiely what today Ray Tracing budgets should be focued on at the moment with todays hardware since they seem to make the biggest visual impact imo.
EU5 is without a doubt making some mind blowing tech and constantly setting the bar for most fields of Gaming Visuals, Mechanics, and Creation. I mean, they better be with their massive amount of resources and money at their disposel for RnD. Also, Its geat the industry is pushing and focusing on Visuals so insanely but at the same time I feel that physics simulation is awlways an after thought or not even used that much. I remember games from early to mid 2000s that have more dynamic physics sims than most games today. I know Physics is really taxing but so was Ray Tracing. Ridgid body is pretty simple. Its cloth, fluid, and softbody physics I want to see start breaking new grounds in realtime gaming.
I have a NASA pen, I worked as an astronaut.
I would love to hear your thoughts on the PS5 specs after watching the Mark Cerny Road to PS5 video with the context of the UE5 demo in mind
i really like to know your thoughts on ps5's architecture (specially it's I/O capabilities ) from an actual developer's perspective
The immersion is going to be off the charts. I'm getting spooked by cascading pebbles and static statues.
19:50 my character would never do this prior to Coronavirus, and definitely not during. they need pay attention to lettkng you customize your character tendencies to better complement their newer engines for more immersion.
That is implemented by game developers though. The game engine is giving them the option to do so, which is demonstrated.
The water looks terrible, just admit it. ;)
I thought it looked really good, just not as good when compared to everything else. I havent seen better water in other games though, which games have done it better?
Terrible water yeah kinda. But pretty awesome real-time fluid simulation. So it looks worse because we've gotten good at faking it. So I don't know if simulating it is worth it at this point but it's still interesting because it could open up fluid dynamics for new kinds of gameplay. Imagine a boat game with realistic currents and better physics
That probably has to do with the devs.
screen 100% blurry
him: "Their motion blur is nice"
me: "I hope i can turn that off"
I was thinking the same thing :))
Awesome video dude. Explains almost every individual feature in an accessible way, that even layman can understand, whilst still being thorough and technical. Can't wait for your next Unreal 5 breakdown.
Yes I would definitely like to see your in-depth analysis of the technology and techniques involved in creating this engine.
Looks amazing! However, I hope water physics and hair animation improves soon. A ponytail moving back and forth with every step just isn't realistic.
On the other hand, Monster Hunter World in this environment would be a dream!
Great job, guys! 👍
This was an excellent video. You definitely deserve more subs. And please react to Mark Cerny's deep dive on the ps5's architecture. Would be really cool to get your opinion about it especially about the ssd.
Thank you for your time and insight on this subject I appreciate it and I enjoyed watching your discussion about on how amazing the graphics have changed in the past two decades.

Welcome to the new reality of "Your Game Download will be finished downloading in approximately: 4 days, 19 hours, 33 minutes (7.5TB)"
;)
Yeah, developers aren't going to be using 8k textures in their games. 4k textures are good enough, 8k will be for rare instances. This demo went balls to the walls with it.
Now (multiple) Gigabit/s fiber internet has much more importance than ever. Sadly most of the populous (some places less than others) is still cut off from such high speeds.
Surely even a decently fast 400 MBit/s line would take easily days for that to download. Though that is ignoring the fact that in its current state flash (or competing) storage is way too expensive to offer speeds of multiple GB/s for multiple TBs of size below many hundreds of $. Heck, the normal PS5 cannot even have a single TB as it would blow the budget at those almost 6 GB/s uncompressed speeds. And streaming multiple GB/s at low latency from the internet is unrealistic at best, meaning this could actually be a case where cloud gaming could make sense if latency is low enough with "just" 200 to 300 MBit/s of downstream for a nearly lossless image. Surely, we aren't there yet either way, at least for large-scale games for the masses.
Type awesome on your keyboard. Something awaits you.
The collision detection was virtually an afterthought (collision detection on all those polygons).🤯
Like you, I'm most interested in the data model they're using. Calculating all those planes is REALLY difficult. They had to be calculating a lot of that in advance, as there's no other way. This is one of those instances where infinity creeps in (I have a serious aversion to infinity).
It was Unreal that got me into PC gaming, I even named the first PC's I built as Unreal, Unreal2 & Unreal3 (Moore's Law broke down for a bit (a decade)). You should do a reaction video to the original Unreal 'flyby', it was equally mindblowing as it was so far ahead of anything else. I made a bet while in college (~2003) that games would be photo-realistic in a decade. I lost that bet but we are in exciting times.
Something I've wondered about for some time; Is with such realism, could people get PTSD? I once scared the hell out of a girlfriend when I called out the position of a sniper in my sleep. Being an FPS fan for some time shooting & getting shot isn't a big deal (it's virtual and you'll respawn in seconds). It was in a CoD game where I actually felt helpless, that's not an emotion I was expecting. It's "just a game".
