@@AdamWebb1982 iracing is a single core game, it doesn't even use a second core. So on a PC if you have no headroom on your strongest cores you will be bottlenecks I had a 9700F and I was 100% utilisation on the CPU, now I have a 12600k I am only using 35% of the CPU which means I am now GPU bound :)
What you have to remember is that iRacing is running on the Nascar Racing 2003 Season engine. It's running on a nearly 2 decade old engine, so it's actually quite impressive it even looks remotely nice still. Even considering the highly modified version of the engine released in 2008, that's still 14 year old technology.
I mean kinda true, but not really. iRacing mentioned that their code was based on NR2003 when they started out, but since now it is already so many times rewritten and refactored, that is not really anymore comparable to the old NR2003 code.
Just a headsup - this doesn't work in VR mode yet. You get the image only projected in one eye. If you do think it works you're probably running vrperfkit, which seems to overrule the FSR option. You don't get the 1-eye issue, but FSR simply isn't being used at all, even when it's turned on. Iracing is aware so hopefully they'll manage to patch this.
One thing to try to load up the gpu is the turn up the options, I noticed you had a few thing on medium and a few things off. If you switch these on and then try FSR you may get higher gpu usage without a lowering of FPS.
The only real downside to using FSR would be if you use a native resolution of anything less than 1440. My monitors are all 1080p and using FSR on even the quality mode has far too low of a visual degradation than I can tolerate. It's just blurry and even some dash elements can be a pain to read at a glance. If you're on 1080p screens, I'd recommend leaving FSR off for now. FSR 2.0 might have better results if we get that in the future.
Soon there will be FSR 2.0, this is a temporal upscaling technique. Little less frames gain than this version but much more higher quality picture. FSR 1.0 is better for lower spec systems, FSR 2.0 works best on high end systems. All in all, these techniques extend the life span of everyone’s hardware so thanks for that AMD!
Did my own benchmarking over the weekend, Ryzen 5600x 3070 32Gb ram. I used a replay from first lap at Winton against Ai, Winton being a recent track has lower farmerate than most. My stock settings have me 92 FPS average, FSR Ultra 94 FPS and balanced have me 96 FPS but looked horrible on tripple 1080 monitors.I This encouraged me to try other things, I found 6 FPS by turning off SKY (AMD's Hyper threading) and another 3 FPS by tightening my ram timings so ended up with 101 FPS without FSR.
If only it worked in VR.. Between FSR not working in VR, and shadow maps having been combined into 1 setting, VR-users have lost around 20-30fps on racestarts :(
Great video Dave. I wouldn't blame your processor. I think it has more to do with iracing not being optimized to take advantage. On a previous system, I investigated my low fps with what I thought were high end gear and found that when I have the fps drops because of low gpu utilization, CPU utilization was also low. Didn't make sense to me until I saw that only 2 of my 12 threads were pegged at max with the others just hanging out
Dont panic guys im pretty sure thats FSR 1.0. I think like in ACC they gonna add FSR 2.0 and DLSS 2.4 proberly pretty soon, so Dave can do this all over again. I think at the moment your GPU especially in iRacing should stick to native res as high as you can. FSR 1.0 does not look that sharp so the feature basicly ruins its purpose. If FSR 2.0 and DLSS come available you can have a way sharper image on the higher quality modes because the upscalers and temporal denoiser work more effectively. For example a 3090 User doesnt need FSR 1.0 or DLSS without Raytracing on on a gameengine designed for fluid high FPS, but you proberly like the quality mode because the initial native resultion only gets slightly reduced, upscaled and denoised in realtime and then downscaled to the resolution you are playing on, which implemented correctly will get you more FPS and a better imagequality. In Asetto Corsa Competizione DLSS is basicly insane, im still in shock how good this game looks and runs in WQHD on my setup and im only running a RTX 2070.
Really want to try this even though I'm CPU limited at the moment. Unfortunately, it currently doesn't work as it's supposed to in VR and you can only see out the left eye. Thanks for doing this though, hopefully iRacing gets a fix in and I can test on my system.
you can use the VR performance toolkit to easily try it out in VR. I found it wasn't worth it because of the reduced visuals (they are really obvious in VR) and it didn't affect the performance of the first lap, so not worth it at all for me. I have same spec PC as dave
@@lemurdreamur9257 you’ve been able to use FSR 1.0 on iRacing for a couple years now. You just had to download the VR performance toolkit separately. It doesn’t really help much unless you’re running a really high res headset (like a reverb) with a low to mid range GPU (like a 3060). Even then it’s not all that much better than rendering at a lower res and using other AA techniques. It does allow for you to run lower resolution on the sides and higher in the center which is nice. Although, I’m not sure if iRacings native implementation allows for fiddling with this. It may in the ini files. But it really only help people who are very GPU limited. Most VR users are CPU limited on iRacing. Honestly, the best thing iRacing can do is upgrade its engine to allow it to get better use of CPU’s as it still basically only uses one core. It’s best bet would be to upgrade to graphics engine like unreal 5 that is able to make much better use of CPU and GPU power. Providing much better graphics at a smaller compute cost.
Dave, you should consider trying SMAA over FXAA, it is supposed to be a superior engine with better frame rates, I could be wrong but might be worth checking out.
Haven’t had any issues with my 2070 on trips at 1440p, but will give this a look to see if I can get 120 fps at each track. Some tracks I’m dipping into the 80-90 range so thanks for this video, see how it helps.
The drop in performance on the 3090 system is due to CPU overhead of FSR being added to an already CPU limited situation. FSR is only really useful if the GPU usage ever hits 100%. Even a 12900kS or a 5800x3D will probably bottleneck a 3090 in iRacing.
FSR is only ok if you run 1440 or 4k screens where image fidelity is not as noticeable. It's utter trash on anything 1080 though. I also have tried this on 1440p single screen and it's still annoying quality wise, AMD is making progress, but not there yet, good technology progress though.
i have the exact same spec as u dave on your machine, so for higher spec machines is it just best not to use it as u gained like 3 FPS for a worse image, as having no FSR is the best image right? I just wish iracing updated its graphics engine and had it more optimised
I have the exact same spec PC as you and I only use VR. I usually get the 90fps I need, except for that first lap. Using this AMD AA with the VR performance toolkit didn't help that first lap at all. it's all CPU. Plus it made the visuals look horrible. in VR you are absolutely pixel peeping, so I'm not sure any upscaling technique will ever be worth it We need a special mode for that first lap. I'd definitely switch that on
So does having more frames per sec will you get a far better ability to see and react to the car . Will your drivimg be more accurate I am still in my PS4 ACC 60 fps and I feel like I am missing a lot of action ? I have a t300 / open wheel add on / t lcm pedals / mounted on a wheel stand. I know for a fact my stand is very wobbly and I lose a to of FFB .
Iracing is ridiculously unoptimised still for incredibly high end systems. I've a 5950x that boosts to 5.1ghz, RTX 3090 overclocked and watercooled, 64gb DDR4 at 3800mhz with iracing on a gen 4 NVME M.2. Running triple 1440p performance is incredibly underwhelming, gpu just tootles along at 60% usage. Iracing seriously needs a new engine, it's a dated potato. To be cpu bottlenecked with my cores that iracing is using hitting 5.1ghz is just laughable. I'm only getting 100fps or there abouts, but nowhere near the framerate limits I've set or what my monitors are capable of (144hz). There's so much more power to be used on the gpu, yet a 5.1ghz cpu isn't good enough on a game that's 15 years old.....please iracing lol. Don't get me started on watching replays on triple 1440p lol. It's about time they dumped this crap engine and got with the times, it's not like they don't make enough money, absolutely raking it in by the millions they are.
They refused to acknowledge their shit tyre model until real F1 and Gt3 drivers shat on it when they played during lockdowns. Before that, they ignored their paying customers who complained about the same thing, thinking they know what's best. I'm sure they won't change the engine unless Verstappen and Norris complain about it(which they won't because they can afford the best PCs)
@@funkytransport I am now haha. I feel cleansed lol. They just frustrate me. Iracing/sim racing is my hobby, a passion if you will. Iracing is such a good service for competitive racing but it's so dated and should be so much better.
Ooh just a quick update I don't use FSR at all quality of resolution is not good and again higher fps is pointless it's too unstable 90 fps is the sweet spot..even for those high end Gpus
Been trying to change my settings the last few days without affecting my stream, beginning to wish I'd left it as it was 😂, will try your suggestions later, as I'm now running in ultra, looks good on my screen but my stream stutters a bit.
This tech came out for CSP on Assetto Corsa a while back and I wasn't that impressed. The framerate increase is real, but the weird graphical artifacts it creates just weren't a worthwhile tradeoff. I'd rather sacrifice a few settings for a nice smooth native resolution experience. I do think it would be a solution for those who genuinely have trouble getting any decent performance in normal modes, running an older GPU etc.
DLSS 1.0 and FSR 1.0 weren't great but version 2.0 is a big upgrade and takes quite a bit to spot the difference even from still photos. Hopefully its not a big upgrade for iRacing to go from FSR 1.0 to FSR 2.0
Hopefully we'll see FSR 2.0 in AC. I believe it's only 1.0 for now? Still, I have a 4K OLED TV and the current FSR does wonders for me and my Titan X while I wait for GPUs like the RTX 3070/3080 or RX 6800 to come down in price more.
We all played iRacing years ago on our computers and now Dave has i9 and rtx 3090 and we are looking for fps??? That must be something wrong with iracing.
my GPU usage is always at about 70% if it goes above I start to get frame drops. Does this mean I am CPU bottlenecked? My CPU usage is low and core by core brakedown inside fpsVR( I play VR only) doesnt show 100% utilization of any cores.
You could be thermally throttling if your always at 70% usage, you may need to refurbish your card replace the thermal pads and paste *( I recommend K5-Pro for pad replacement look up a video called more FPS for $10 it’s on the LTT channel and use a good paste that last a long time like MX-4, Noctua NT-2, or my fav. Thermalright TFX it’s better than TG Kryonaut and last 8 years don’t use AS5 it suck’s )* , a CPU bottleneck is when your at 99-100% CPU usage, I bet you use Epic settings try high it looks pretty much the same and will drop the load down to about 30% usage, it really sound like a thermal issue to me
Not something I've tried Dave, but I may have a look and see what results I get. My PC is an i5-9400F 16GB DDR4 Ram and GTX 1660 Super graphics card which copes fairly well with iRacing. I have noticed that the loding on the GPU is much less than the CPU so I think it's an iRacing thing.
@@ady.marwan I couldn't get the sim to load without crashing, so I couldn't get into the settings menu in order to change that. I ended up just reinstalling iRacing. That did the trick. Now I just have to go back and map my buttons and configure wheel and pedals.
@@JKRacing24 if that ever happens again just delete the config file and iracing will give you a choice of either the recomended or minimum setting when you next launch the sim.
If I understand correctly, it is not necessary to own an AMD video card. But at the same time, on my 3080 card and 1440 resolution UW monitor, I did not get an increase in FPS. Just a noticeable drop in picture quality.
You need a GPU that's bottlenecking performance to make use of FSR (i.e. struggles to render consistently at native resolution) and the RTX3080 is simply so powerful that you're not going to get an appreciable performance uplift in iRacing on a 3440x1440 monitor to make the graphical downgrade worthwhile.
Noob question, would this only come into play with 120hz plus pc monitors? I have a decent spec pc with 5900x cpu, 32gb ram and rtx 3060, but using a single 4k 60hz TV... because I know the TV is limited to 60hz I tend to hard limit it in the two iracing in game settings too because the tv doesnt have vsync/freesync. Whether that's stupid or not I have no idea😂 help is appreciated
Try caping IRacing at a higher FPS than your monitor but not a multiple of its refresh rate or screen tearing will be an issue. I use 107 FPS limit with my 60Hz monitors, trees in the distance appear smoother when cornering compared to capping at 60Hz.
hi dave , can i ask if you have done a video about how i racing does its divisions and how Meany times do I need to race in order to do well for the season e.g. is it once a week and if so how would i compare to someone who races 3 times a week
Your division is set at the start of a season based on your irating. iRacing averages your weekly race results if you race more than 4times a week, less than that and it just takes your best result of the week. So if you race 1ce a week vs someone who races more, you aren't losing out on the points side of things.
You realise you change the native resolution (Windows res) to a lower res say 1080p then you use FSR and ingame Res scaler to set the res you want, It then upscales the native 1080p image to the ingame image so if u set in game to 4k, It will upscale native 1080p (Set in windows) to 4k (As set in game with FSR enabled)
Interesting. I play Assetto Corsa, but I can't really tell the difference between Ultra and native. At quality I do notice the interior looking more realistic due to the reduction in sharpness, so I like that mode.
Ive been planing on getting iracing for a bit now but idk what a good budget pc is,(i found one but dk if its good).Also when i get iracing, does anyone know a good GT car to pick for team enduro races?
as an example, i can tell you i was running iracing on about 100fps on a single 34'' screen with my old computer with a GTX980 graphics card with 16gb of ram. i lowered the graphics settings and that was running smoothly. I had to upgrade for triple monitors, but single monitor really didnt take much power to run. hope this helps.
BMW M4 is in my opinion a very solid choice for endurance races (maybe even one of the best) especially when new to it all Edit: The new AMG GT3 is also very nice but a little more challenging to drive and a ton of fun :))
@@nrome49 This is what annoys me, people saying "I get xx framerates at yy track MINES JUST AS GOOD" but no mention of any graphic/shader settings, whether solo, online, 10 car race, 40 car race.. online/ AI... single screen/triple screen/1080/2k/4k etc.. annoys me.

Thanks Dave, have a subscribe lol. I run a fairly beefy system, 5600x, x570 MSI Meg unify, 3080, 32gb 3600 ram with 3x samsung 970 pro (1tb and 2 x2tb) M.2 drives on 5760x1080 triples and my frames per track/car combo can vary from 300 fps in a old car/old track combo, to 50fps on a new car/ new track full field (until pack spreads out) etc (i dont count replay mode frame rates) I run a lot of low/med left option settings in game except shader quality, mileage varies for everyone and it's not productive unless ALL video settings andf specs are shared to help all parties fine tune their frames for best bang for buck
@@FunzR32 last time i ran imola it was a vrs sprint with 25 cars on track and the graphics slider was halfway between peformance and quality, plus i run a 2k single monitor
Dave your fps seems very low considering you have a better cpu and gpu than me. I run triple 1440p 170hz screens on a 3080 and 9700k 32gb ram 3200mhz and i get 80fps at the grid and 120fps to 130fps once the grid spreads out a bit and that was before fsr. What i did notice today was my normal FPS was lower so I'm wondering if the last Nvidia update slowed us down as it has MANY times when there is a new GPU due to be announced. I'll try rolling back the Nvidia driver to the one before and see how i do.
FSR is an AMD thing. Is it really doing anything helpful on an Intel CPU and an Nvidia GPU? I would assume there would be a difference if you had an AMD CPU and GPU? I have no idea other than FSR must certainly be optimized for AMD stuff at the very least.
FSR is an open-source, software-based solution. It doesn’t require any specific hardware to work, although for best results it requires a graphics card from within the last couple of generations.
I believe iRacing only implements FSR v1 currently, which most reviews said isn’t all that great. FSR 2.0 is supposedly much better, so when that comes around the results should be better.
I'm playing with triple 4k at 110 on ultra with a 3080ti and a 11900k. It's very odd that the frame rate your getting at that resolution with that build
iRacing doesn't stress the GPU, and isn't anywhere near GPU limited. Whenever this occurs, there's either two issues: 1) You're CPU limited (render thread(s) pegged at 100%), 2) The code is not optimized (runs poorly, underutilized hardware). In both of those instances, increasing your CPU performance will yield results, which is why your better CPU over Dave's renders (hah, pun!) an increase in FPS.
Have you tried Smart Access Memory and Fidelity Super-resolution Dave? It's from AMD but works on NVIDIA cards too. I'm away working so haven't been able to give it a go, but from the video I watched it gives quite an improvement in FPS and resolution. Linus Tech Tips did a video on it called "AMD Says You’re Doing it Wrong" a few weeks ago, worth a look I reckon.
@@lemurdreamur9257 Yes you are correct. It looks like combined and most games only hit some of the cores hard. That is the point. if GPU usage is 60-90% and CPU usage is >50% by switching to CPU encoding you will lessen the GPU load and stress the CPU more. Think of it as even weight distribution . if the GPU usage goes down and output is relatively same you could maybe run higher GFX settings = more eye candy. Just a thought.
@@davecamyt Should try again with all cores. If one core is that low it doesn’t sound like a CPU bottleneck to me. CPU needs to be maxed for it to be the bottleneck of your system. I’d says it’s just a poorly optimised game or the update needs a few tweaks.
@@ViszlaBoss it is indeed a CPU bottleneck. iRacing only uses 2 cores and, like every other sim on the market, only 1 core for all the physics calculations. You can see the exact same "issue" on every other sim. The only difference between iRacing and the rest is, iRacing looks garbage in comparison. When you want to see how hard a CPU bottleneck can fuck your CPU start an online race with 80 driver in ACC :D
Since the update my iRacing is litterally unplayable, my CPS monitor is going haywire. Before the update I would pull 144fps on my triple screens, now I can't even test drive anymore. Actually unacceptable
@@eddielovesf1 There are answers on the forums, if you get track loading errors there is a fix if you run AMD graphics. If you have other issues my best advice would be hard reinstall, back-up you setting files such as setups and settings, and remove all files manually after a windows uninstall, both the program files folder, as well as the iracing documents folder, and the appdata local and roaming folder. That has fixed it for me for now, iRacing is truely bad at updates and it really needs to learn to provide a 100% clean install function
My 5900X lets my 3080 Ti stretch it’s legs just enough in an ACC a race with 30 cars at 1440p high setting I get 180-250fps during the race when the stands are full, 300+ in qualifying and my GPU is around 56% usage while playing ACC, my CPU is at 14%-16%
@@davecamyt I'm going to try again, the other day I tried this after selecting the Aliasing method, I still didn't have any of options to select one of the upscaling, when I clicked on the arrow was only showing me "none"
its a shame iracing currently using FSR 1.0 version instead of recently released 2.0. Thanks for the tests, i guess fsr will be much more relevant for those who are using triple 4k monitor setup with rtx 3090 and good cpu or just slower gpu in general.
Funnily enough, I enabled FSR to try if it will make a difference in VR (I have the HP Reverb G2 and a 3080) and the image was only projected into one eye. So right now completely useless to me :( (I did not do any research afterwards to try and troubleshoot it, so it might be my setup that's at fault)
In vr you wouldn't use the fsr settings in iracing. PCVR users already have this ability in any vr game. I don't have personal experience with windows mixed reality which is what the hp reverb uses, but there's probably a way to change resolution scaling from inside WMR. If not, install Steam VR and run it on top of WMR, set your resolution scaling in steamvr, then launch iracing over that and ignore the fsr settings in iracing
your comparison of GPU usage with other sims would be relevant ONLY if the frame rate where the same. There were NOT. there were lower, means other Sims are not as optimized than iRacing and need more GPU to render even at a lower frame rate. Mean those sims are GPU bounded, were iRacing is CPU bounded , more precisely 1 core bounded, showing the whole CPU usage % is completely irrelevant too, as if 1 core is used at 100% it's the bottle neck for the whole game.
It is iRacing that is not well optimized though.....All those other sims fully utilise the GPU, which is what you want. It is much better to off load suitable workloads to the GPU, as the GPU is much better at it. At some point iRacing is going to need to switch to a new engine because single core CPU performance is increasing much more slowly than GPU performance, and throwing all the workload at 2 or 3 cpu cores is limiting them.
@@andycarroll4897 You are confusing optimized with using more feature. iRacing use DX11 and is quite old, and have way less features than more recent sims, like post-processing. Optimizing means the feature they use, are optimized to use less GPU resources. You are talking about using more of the GPU, that is not the same has optimizing the code/engine. In the end you can run iRacing at 250 fps with all options turned on, when ACC will barely be at 60fps on same PC. But ACC will look, fancier for sure, as it display more stuff. Then you have AMS2, which both has more GFX features and is quite well optimized as it run way better than ACC, especially in VR, and also have more fancy shaders and post-processes than iRacing. (video game dev here)
@@seb-kun No, optimizing means it should make best use of what is available. If the GPU is better at a job than the CPU, then the GPU should do that job. iRacing is far too reliant on the CPU and doesn't offload enough work to the GPU. That is surely a limitation of the engine they are using, in the same way they are limited with what they can do with the physics & FFB?
@@andycarroll4897 No it's not the same thing. You are taking about optimizing the resources available, optimizing resources assignment. I am talking about optimizing the code to be able to display as much things possible in the most efficient way
@@seb-kun OK agreed, iRacing code is definitely optimised given all it can do using just 2-3 cores, and without heavily taxing the GPU. However, they have had 14 years to get to this point (more if you include NR2003)....Surely now they should be much more focused on taking advantage of the much wider range of resources available in PCs of the last 5-8 years and optimising things more widely so it can scale much better
Ok..I did a lot of homework..your best shot is as follows..set MSI afterburner to a decent underclock..for my 3080 to it's 775 mv@1766 or even go as low to 1710 frequency and in rivertuner set fps to 90 run all your sim racing at this why you ask??

@@ArjanSchepers When he's looking at his settings at 2:00 you can see his resolution is 7560x1440 which is three QHD monitors, not 4k. I also use three QHD monitors with a 3080ti and iRacing is the worst performing out of all of the modern sims. This is probably just due to iRacing being older and not fully taking advantage of modern hardware. I can't fault them for it though because they would have to re-make the game work better on newer computers.
If you have DLSS available use that in the highest quality setting. It is much better, but with you combination 10900K and 3090 it is pretty much also make you running into the cpu Limits... Those options (DLSS/FSR) are mostly for customers with a graphics card that is a little bit underpowered who have a little bit of room on the CPU side. For them this is absolutely nice to have but with a High End Beast it is only useful if you run 8k for example or triple 4K Monitors....
Dave, FSR is actually AMD specific. You will notice in the iRacing menu, that it states "AMD" ... meaning the real benefit would be for AMD gpu's not nVidia
Not true. Yes, FSR is indeed a technology developed by AMD, but it does officially support any Nvidia card from the 10xx and 16xx lines and newer. FSR is part of AMD´s GPUopen program, the Source Code for it is entirely Open Source, If it had anything in the code that would make FSR intentionally slower on Nvidia cards (or faster on AMD ones) it would have been called out by now. AFAIK FSR in implemented at the shader level, the limiting factor would be a given cards general shader performance.

The CPU usage isn't my actual CPU usage. I didn't bother monitoring the CPU 👍

What you have to remember is that iRacing is running on the Nascar Racing 2003 Season engine. It's running on a nearly 2 decade old engine, so it's actually quite impressive it even looks remotely nice still. Even considering the highly modified version of the engine released in 2008, that's still 14 year old technology.
I mean kinda true, but not really. iRacing mentioned that their code was based on NR2003 when they started out, but since now it is already so many times rewritten and refactored, that is not really anymore comparable to the old NR2003 code.
Brakes in VR though, the one place it’s needed most.
Just a headsup - this doesn't work in VR mode yet. You get the image only projected in one eye. If you do think it works you're probably running vrperfkit, which seems to overrule the FSR option. You don't get the 1-eye issue, but FSR simply isn't being used at all, even when it's turned on.
Iracing is aware so hopefully they'll manage to patch this.
One thing to try to load up the gpu is the turn up the options, I noticed you had a few thing on medium and a few things off. If you switch these on and then try FSR you may get higher gpu usage without a lowering of FPS.
The only real downside to using FSR would be if you use a native resolution of anything less than 1440. My monitors are all 1080p and using FSR on even the quality mode has far too low of a visual degradation than I can tolerate. It's just blurry and even some dash elements can be a pain to read at a glance. If you're on 1080p screens, I'd recommend leaving FSR off for now. FSR 2.0 might have better results if we get that in the future.
Soon there will be FSR 2.0, this is a temporal upscaling technique. Little less frames gain than this version but much more higher quality picture. FSR 1.0 is better for lower spec systems, FSR 2.0 works best on high end systems.
All in all, these techniques extend the life span of everyone’s hardware so thanks for that AMD!

This encouraged me to try other things, I found 6 FPS by turning off SKY (AMD's Hyper threading) and another 3 FPS by tightening my ram timings so ended up with 101 FPS without FSR.
If only it worked in VR..
Between FSR not working in VR, and shadow maps having been combined into 1 setting, VR-users have lost around 20-30fps on racestarts :(
My iracing Career is dying for the time being my pc is starting to slow right down can’t wait to upgrade in the future
just want to say: thanks for the time and effort you put in these videos for us :)
Appreciate that 😁
Great video Dave. I wouldn't blame your processor. I think it has more to do with iracing not being optimized to take advantage. On a previous system, I investigated my low fps with what I thought were high end gear and found that when I have the fps drops because of low gpu utilization, CPU utilization was also low. Didn't make sense to me until I saw that only 2 of my 12 threads were pegged at max with the others just hanging out
Great Vid Dave! Love the new content ideas
Dont panic guys im pretty sure thats FSR 1.0. I think like in ACC they gonna add FSR 2.0 and DLSS 2.4 proberly pretty soon, so Dave can do this all over again.
I think at the moment your GPU especially in iRacing should stick to native res as high as you can. FSR 1.0 does not look that sharp so the feature basicly ruins its purpose.
If FSR 2.0 and DLSS come available you can have a way sharper image on the higher quality modes because the upscalers and temporal denoiser work more effectively.
For example a 3090 User doesnt need FSR 1.0 or DLSS without Raytracing on on a gameengine designed for fluid high FPS, but you proberly like the quality mode because the initial native resultion only gets slightly reduced, upscaled and denoised in realtime and then downscaled to the resolution you are playing on, which implemented correctly will get you more FPS and a better imagequality. In Asetto Corsa Competizione DLSS is basicly insane, im still in shock how good this game looks and runs in WQHD on my setup and im only running a RTX 2070.
Hopefully they fix this for VR in the near future hotpatches
Really want to try this even though I'm CPU limited at the moment. Unfortunately, it currently doesn't work as it's supposed to in VR and you can only see out the left eye. Thanks for doing this though, hopefully iRacing gets a fix in and I can test on my system.
Same, hope they get it sorted for VR
This would be huge for vr
I was just going to ask if this worked for VR. I hope they sort it out.
you can use the VR performance toolkit to easily try it out in VR. I found it wasn't worth it because of the reduced visuals (they are really obvious in VR) and it didn't affect the performance of the first lap, so not worth it at all for me. I have same spec PC as dave
@@lemurdreamur9257 you’ve been able to use FSR 1.0 on iRacing for a couple years now. You just had to download the VR performance toolkit separately. It doesn’t really help much unless you’re running a really high res headset (like a reverb) with a low to mid range GPU (like a 3060). Even then it’s not all that much better than rendering at a lower res and using other AA techniques. It does allow for you to run lower resolution on the sides and higher in the center which is nice. Although, I’m not sure if iRacings native implementation allows for fiddling with this. It may in the ini files. But it really only help people who are very GPU limited. Most VR users are CPU limited on iRacing.
Honestly, the best thing iRacing can do is upgrade its engine to allow it to get better use of CPU’s as it still basically only uses one core. It’s best bet would be to upgrade to graphics engine like unreal 5 that is able to make much better use of CPU and GPU power. Providing much better graphics at a smaller compute cost.
Dave, you should consider trying SMAA over FXAA, it is supposed to be a superior engine with better frame rates, I could be wrong but might be worth checking out.
Nice to see other types of videos on your channel
Haven’t had any issues with my 2070 on trips at 1440p, but will give this a look to see if I can get 120 fps at each track. Some tracks I’m dipping into the 80-90 range so thanks for this video, see how it helps.
The drop in performance on the 3090 system is due to CPU overhead of FSR being added to an already CPU limited situation. FSR is only really useful if the GPU usage ever hits 100%. Even a 12900kS or a 5800x3D will probably bottleneck a 3090 in iRacing.
FSR is only ok if you run 1440 or 4k screens where image fidelity is not as noticeable. It's utter trash on anything 1080 though. I also have tried this on 1440p single screen and it's still annoying quality wise, AMD is making progress, but not there yet, good technology progress though.
FSR looks horrible at 1080p unusable
Saddly, it doesnt work with VR. Or i cant set it up .
Great stuff as always😎
i have the exact same spec as u dave on your machine, so for higher spec machines is it just best not to use it as u gained like 3 FPS for a worse image, as having no FSR is the best image right? I just wish iracing updated its graphics engine and had it more optimised
Tried it and didn't like it at all. not worth the drop in visuals for a few more frames
I set mine to Ultra and even that has boosted my FPS, with very little fidelity difference. Can run 144/1440P most of the time now.
I have the exact same spec PC as you and I only use VR.
I usually get the 90fps I need, except for that first lap. Using this AMD AA with the VR performance toolkit didn't help that first lap at all. it's all CPU. Plus it made the visuals look horrible. in VR you are absolutely pixel peeping, so I'm not sure any upscaling technique will ever be worth it
We need a special mode for that first lap. I'd definitely switch that on
These graphic settings are only useful on a screen right? No VR
also wondering this
Currently broken they are trying to find a fix. Should come hopefully but we need it badly.
So does having more frames per sec will you get a far better ability to see and react to the car .
Will your drivimg be more accurate I am still in my PS4 ACC 60 fps and I feel like I am missing a lot of action ?
I have a t300 / open wheel add on / t lcm pedals / mounted on a wheel stand.
I know for a fact my stand is very wobbly and I lose a to of FFB .
Yes the more fps you have the better. Not as important in sim racing as in first person shooters, but if you can get 100fps you're good 👍
Iracing is ridiculously unoptimised still for incredibly high end systems. I've a 5950x that boosts to 5.1ghz, RTX 3090 overclocked and watercooled, 64gb DDR4 at 3800mhz with iracing on a gen 4 NVME M.2. Running triple 1440p performance is incredibly underwhelming, gpu just tootles along at 60% usage. Iracing seriously needs a new engine, it's a dated potato. To be cpu bottlenecked with my cores that iracing is using hitting 5.1ghz is just laughable. I'm only getting 100fps or there abouts, but nowhere near the framerate limits I've set or what my monitors are capable of (144hz). There's so much more power to be used on the gpu, yet a 5.1ghz cpu isn't good enough on a game that's 15 years old.....please iracing lol.
Don't get me started on watching replays on triple 1440p lol. It's about time they dumped this crap engine and got with the times, it's not like they don't make enough money, absolutely raking it in by the millions they are.
They refused to acknowledge their shit tyre model until real F1 and Gt3 drivers shat on it when they played during lockdowns.
Before that, they ignored their paying customers who complained about the same thing, thinking they know what's best.
I'm sure they won't change the engine unless Verstappen and Norris complain about it(which they won't because they can afford the best PCs)
you ok there?
@@funkytransport I am now haha. I feel cleansed lol. They just frustrate me. Iracing/sim racing is my hobby, a passion if you will. Iracing is such a good service for competitive racing but it's so dated and should be so much better.
Ooh just a quick update I don't use FSR at all quality of resolution is not good and again higher fps is pointless it's too unstable 90 fps is the sweet spot..even for those high end Gpus
Been trying to change my settings the last few days without affecting my stream, beginning to wish I'd left it as it was 😂, will try your suggestions later, as I'm now running in ultra, looks good on my screen but my stream stutters a bit.
I don’t use anything which interferes in me seeing my markers
Amazing video, great you catched that you're CPU bottlenecked.
This tech came out for CSP on Assetto Corsa a while back and I wasn't that impressed. The framerate increase is real, but the weird graphical artifacts it creates just weren't a worthwhile tradeoff. I'd rather sacrifice a few settings for a nice smooth native resolution experience. I do think it would be a solution for those who genuinely have trouble getting any decent performance in normal modes, running an older GPU etc.
DLSS 1.0 and FSR 1.0 weren't great but version 2.0 is a big upgrade and takes quite a bit to spot the difference even from still photos. Hopefully its not a big upgrade for iRacing to go from FSR 1.0 to FSR 2.0
Hopefully we'll see FSR 2.0 in AC. I believe it's only 1.0 for now? Still, I have a 4K OLED TV and the current FSR does wonders for me and my Titan X while I wait for GPUs like the RTX 3070/3080 or RX 6800 to come down in price more.
We all played iRacing years ago on our computers and now Dave has i9 and rtx 3090 and we are looking for fps??? That must be something wrong with iracing.
my GPU usage is always at about 70% if it goes above I start to get frame drops. Does this mean I am CPU bottlenecked? My CPU usage is low and core by core brakedown inside fpsVR( I play VR only) doesnt show 100% utilization of any cores.
You could be thermally throttling if your always at 70% usage, you may need to refurbish your card replace the thermal pads and paste *( I recommend K5-Pro for pad replacement look up a video called more FPS for $10 it’s on the LTT channel and use a good paste that last a long time like MX-4, Noctua NT-2, or my fav. Thermalright TFX it’s better than TG Kryonaut and last 8 years don’t use AS5 it suck’s )* , a CPU bottleneck is when your at 99-100% CPU usage, I bet you use Epic settings try high it looks pretty much the same and will drop the load down to about 30% usage, it really sound like a thermal issue to me
Not something I've tried Dave, but I may have a look and see what results I get.
My PC is an i5-9400F 16GB DDR4 Ram and GTX 1660 Super graphics card which copes fairly well with iRacing.
I have noticed that the loding on the GPU is much less than the CPU so I think it's an iRacing thing.
Dave, maybe I didn't see the screen but are you sure you selected a lower in-game resolution in the first benchmark?
yup..... i tried this and now my iracing wont load it just crashes as soon as the race tries to load.
@@JKRacing24 try changing the antialiasing to either FXAA or something else.. then restart..
@@ady.marwan I couldn't get the sim to load without crashing, so I couldn't get into the settings menu in order to change that. I ended up just reinstalling iRacing. That did the trick. Now I just have to go back and map my buttons and configure wheel and pedals.
@@JKRacing24 if that ever happens again just delete the config file and iracing will give you a choice of either the recomended or minimum setting when you next launch the sim.
@@Max-Barnes Ok. Thank you. I will keep that in mind.
If I understand correctly, it is not necessary to own an AMD video card.
But at the same time, on my 3080 card and 1440 resolution UW monitor, I did not get an increase in FPS. Just a noticeable drop in picture quality.
You need a GPU that's bottlenecking performance to make use of FSR (i.e. struggles to render consistently at native resolution) and the RTX3080 is simply so powerful that you're not going to get an appreciable performance uplift in iRacing on a 3440x1440 monitor to make the graphical downgrade worthwhile.
Perhaps watch the video before commenting lol
Does anyone know if FSR makes a difference for lower range setups? Or will it only really help on a PC that can already manage medium-high settings?
I think that's where it'll help the most 👍
Can’t use any of these. For whatever reason they look extra shit on my monitor
Yeah same for me looks awful
I tried this on my 1080p 49” and couldn’t stand it. Anything less than 1080 on that was too hard to look at. Glad it works better at 2k.
Also running a 10900k and 3090. Messed about with it the other day but it’s not like we are short of FPS anyway so won’t be using it
Noob question, would this only come into play with 120hz plus pc monitors? I have a decent spec pc with 5900x cpu, 32gb ram and rtx 3060, but using a single 4k 60hz TV... because I know the TV is limited to 60hz I tend to hard limit it in the two iracing in game settings too because the tv doesnt have vsync/freesync. Whether that's stupid or not I have no idea😂 help is appreciated
Try caping IRacing at a higher FPS than your monitor but not a multiple of its refresh rate or screen tearing will be an issue. I use 107 FPS limit with my 60Hz monitors, trees in the distance appear smoother when cornering compared to capping at 60Hz.

OK I'm confused. You say you used a replay file but graphics options for replay are different to graphics options in Sim. Or am I just wrong?
The sim graphics and replay graphics were transferred from one computer to the other so identical. From one computer to the next 👍
@@davecamyt but I thought the graphics settings had nothing to do with replays. Replay settings are different.
They are, but on the same doc file so it transfers over 👍
hi dave , can i ask if you have done a video about how i racing does its divisions and how Meany times do I need to race in order to do well for the season e.g. is it once a week and if so how would i compare to someone who races 3 times a week
Your division is set at the start of a season based on your irating.
iRacing averages your weekly race results if you race more than 4times a week, less than that and it just takes your best result of the week. So if you race 1ce a week vs someone who races more, you aren't losing out on the points side of things.
I tried them all, and like your system, it was only a minor difference at the top only. So I just run native.
Great video
You realise you change the native resolution (Windows res) to a lower res say 1080p then you use FSR and ingame Res scaler to set the res you want, It then upscales the native 1080p image to the ingame image so if u set in game to 4k, It will upscale native 1080p (Set in windows) to 4k (As set in game with FSR enabled)
Nah for me the graphic loss is to much and gives me heachache at 5120x1440.
Not worth the FPS gain at all.
Interesting. I play Assetto Corsa, but I can't really tell the difference between Ultra and native. At quality I do notice the interior looking more realistic due to the reduction in sharpness, so I like that mode.
Ive been planing on getting iracing for a bit now but idk what a good budget pc is,(i found one but dk if its good).Also when i get iracing, does anyone know a good GT car to pick for team enduro races?
as an example, i can tell you i was running iracing on about 100fps on a single 34'' screen with my old computer with a GTX980 graphics card with 16gb of ram. i lowered the graphics settings and that was running smoothly. I had to upgrade for triple monitors, but single monitor really didnt take much power to run. hope this helps.
BMW M4 is in my opinion a very solid choice for endurance races (maybe even one of the best) especially when new to it all
Edit: The new AMG GT3 is also very nice but a little more challenging to drive and a ton of fun :))
this doesnt make sense because i average about 70 fps in a race at imola and I'm running an i5 2400s 16gb ram and rx470.... how does that work?
on a single 1080p monitor ya
@@nrome49 This is what annoys me, people saying "I get xx framerates at yy track MINES JUST AS GOOD" but no mention of any graphic/shader settings, whether solo, online, 10 car race, 40 car race.. online/ AI... single screen/triple screen/1080/2k/4k etc.. annoys me.

@@FunzR32 last time i ran imola it was a vrs sprint with 25 cars on track and the graphics slider was halfway between peformance and quality, plus i run a 2k single monitor
Dave your fps seems very low considering you have a better cpu and gpu than me. I run triple 1440p 170hz screens on a 3080 and 9700k 32gb ram 3200mhz and i get 80fps at the grid and 120fps to 130fps once the grid spreads out a bit and that was before fsr.
What i did notice today was my normal FPS was lower so I'm wondering if the last Nvidia update slowed us down as it has MANY times when there is a new GPU due to be announced.
I'll try rolling back the Nvidia driver to the one before and see how i do.
I'm recording at a pretty high bitrate too so that will explain the lost fps, although wasn't recording when I did the benchmarks 👍
@@davecamyt No worries, was just a little confused lol
That's what I have. I get 40 at the starting grid and 60-80 on empty road :-/. What the hell
FSR is an AMD thing. Is it really doing anything helpful on an Intel CPU and an Nvidia GPU? I would assume there would be a difference if you had an AMD CPU and GPU? I have no idea other than FSR must certainly be optimized for AMD stuff at the very least.
FSR is an open-source, software-based solution. It doesn’t require any specific hardware to work, although for best results it requires a graphics card from within the last couple of generations.
I believe iRacing only implements FSR v1 currently, which most reviews said isn’t all that great. FSR 2.0 is supposedly much better, so when that comes around the results should be better.
Wrong.
FSR is for all GPUs.
Why is it called AMD FSA if it works with Intel and Nvidia?
Because AMD made it for everyone while Nvidia DLSS was made only for Nvidia cards
I'm playing with triple 4k at 110 on ultra with a 3080ti and a 11900k. It's very odd that the frame rate your getting at that resolution with that build
iRacing doesn't stress the GPU, and isn't anywhere near GPU limited. Whenever this occurs, there's either two issues: 1) You're CPU limited (render thread(s) pegged at 100%), 2) The code is not optimized (runs poorly, underutilized hardware). In both of those instances, increasing your CPU performance will yield results, which is why your better CPU over Dave's renders (hah, pun!) an increase in FPS.
I THOUGHT IT WAS BLURRY AND HORRIBLE
Agreed the minute AA is turned on it lacks real clarity.
why are you only running pcf4 Dave?
I think it looks good enough 👍
@@davecamyt Fair enough, it stutters like crazy for my 1060 but the track looks prettier. Then back to pcf4 lol.
Does it work with vr?
from what I've read so far, there is currently an issue with it in VR and its not rendering 1 lens.
Have you tried Smart Access Memory and Fidelity Super-resolution Dave? It's from AMD but works on NVIDIA cards too. I'm away working so haven't been able to give it a go, but from the video I watched it gives quite an improvement in FPS and resolution.
Linus Tech Tips did a video on it called "AMD Says You’re Doing it Wrong" a few weeks ago, worth a look I reckon.
is this only for AMD builds or also Intel?
AMD FSR is the same thing as DLSS for nvidia

try switching encoding to CPU. GPU encoding is great but you were only using 25% CPU so you have more headroom.
That was just one of the cores I believe 👍
Yeah the cpu is all cores combined I believe. It might read 25% over all but still maxing out one or more cores. I know that's how mine is.
@@lemurdreamur9257 Yes you are correct. It looks like combined and most games only hit some of the cores hard. That is the point. if GPU usage is 60-90% and CPU usage is >50% by switching to CPU encoding you will lessen the GPU load and stress the CPU more. Think of it as even weight distribution . if the GPU usage goes down and output is relatively same you could maybe run higher GFX settings = more eye candy. Just a thought.

@@davecamyt Should try again with all cores. If one core is that low it doesn’t sound like a CPU bottleneck to me. CPU needs to be maxed for it to be the bottleneck of your system. I’d says it’s just a poorly optimised game or the update needs a few tweaks.
@@ViszlaBoss it is indeed a CPU bottleneck.
iRacing only uses 2 cores and, like every other sim on the market, only 1 core for all the physics calculations. You can see the exact same "issue" on every other sim.

I get loading error
@@eddielovesf1 There are answers on the forums, if you get track loading errors there is a fix if you run AMD graphics. If you have other issues my best advice would be hard reinstall, back-up you setting files such as setups and settings, and remove all files manually after a windows uninstall, both the program files folder, as well as the iracing documents folder, and the appdata local and roaming folder. That has fixed it for me for now, iRacing is truely bad at updates and it really needs to learn to provide a 100% clean install function
Thank you i will give this ago 👍.
Never has this issue before.
For stupid ppl like me that has a basically the same pc to yours . What should i run it on ?

Funnily enough, I enabled FSR to try if it will make a difference in VR (I have the HP Reverb G2 and a 3080) and the image was only projected into one eye. So right now completely useless to me :( (I did not do any research afterwards to try and troubleshoot it, so it might be my setup that's at fault)
turn off SPS
@@funkytransport I’ll try that thanks!
@@funkytransport tried this and it didn’t work :/ did you get it working for you?
I can’t get it working either, only one eye projects!!
In vr you wouldn't use the fsr settings in iracing. PCVR users already have this ability in any vr game. I don't have personal experience with windows mixed reality which is what the hp reverb uses, but there's probably a way to change resolution scaling from inside WMR. If not, install Steam VR and run it on top of WMR, set your resolution scaling in steamvr, then launch iracing over that and ignore the fsr settings in iracing
your comparison of GPU usage with other sims would be relevant ONLY if the frame rate where the same. There were NOT. there were lower, means other Sims are not as optimized than iRacing and need more GPU to render even at a lower frame rate. Mean those sims are GPU bounded, were iRacing is CPU bounded , more precisely 1 core bounded, showing the whole CPU usage % is completely irrelevant too, as if 1 core is used at 100% it's the bottle neck for the whole game.
It is iRacing that is not well optimized though.....All those other sims fully utilise the GPU, which is what you want. It is much better to off load suitable workloads to the GPU, as the GPU is much better at it. At some point iRacing is going to need to switch to a new engine because single core CPU performance is increasing much more slowly than GPU performance, and throwing all the workload at 2 or 3 cpu cores is limiting them.
@@andycarroll4897 You are confusing optimized with using more feature.
iRacing use DX11 and is quite old, and have way less features than more recent sims, like post-processing.
Optimizing means the feature they use, are optimized to use less GPU resources.
You are talking about using more of the GPU, that is not the same has optimizing the code/engine.
In the end you can run iRacing at 250 fps with all options turned on, when ACC will barely be at 60fps on same PC.
But ACC will look, fancier for sure, as it display more stuff.
Then you have AMS2, which both has more GFX features and is quite well optimized as it run way better than ACC, especially in VR, and also have more fancy shaders and post-processes than iRacing.
(video game dev here)
@@seb-kun No, optimizing means it should make best use of what is available. If the GPU is better at a job than the CPU, then the GPU should do that job. iRacing is far too reliant on the CPU and doesn't offload enough work to the GPU. That is surely a limitation of the engine they are using, in the same way they are limited with what they can do with the physics & FFB?
@@andycarroll4897 No it's not the same thing. You are taking about optimizing the resources available, optimizing resources assignment.
I am talking about optimizing the code to be able to display as much things possible in the most efficient way
@@seb-kun OK agreed, iRacing code is definitely optimised given all it can do using just 2-3 cores, and without heavily taxing the GPU. However, they have had 14 years to get to this point (more if you include NR2003)....Surely now they should be much more focused on taking advantage of the much wider range of resources available in PCs of the last 5-8 years and optimising things more widely so it can scale much better
Ok..I did a lot of homework..your best shot is as follows..set MSI afterburner to a decent underclock..for my 3080 to it's 775 mv@1766 or even go as low to 1710 frequency and in rivertuner set fps to 90 run all your sim racing at this why you ask??

@@Simlife101 lol I know I was baiting an answer I run 1080 triples on a 2070 Super and get like 140ish on medium settings (could probably bump it up now that I think about it lol)
When you have an i9 and a 3090 and you are still looking for frames that's a problem
Not realty considering he is running triple 4K monitors.
@@ArjanSchepers When he's looking at his settings at 2:00 you can see his resolution is 7560x1440 which is three QHD monitors, not 4k. I also use three QHD monitors with a 3080ti and iRacing is the worst performing out of all of the modern sims. This is probably just due to iRacing being older and not fully taking advantage of modern hardware. I can't fault them for it though because they would have to re-make the game work better on newer computers.
@@mtnbkr2011 You're right, my bad!
If you have DLSS available use that in the highest quality setting. It is much better, but with you combination 10900K and 3090 it is pretty much also make you running into the cpu Limits... Those options (DLSS/FSR) are mostly for customers with a graphics card that is a little bit underpowered who have a little bit of room on the CPU side. For them this is absolutely nice to have but with a High End Beast it is only useful if you run 8k for example or triple 4K Monitors....
iRacing doesnt have DLSS - so not sure what are on about...
There's no DLSS for iRacing?
Dave, FSR is actually AMD specific. You will notice in the iRacing menu, that it states "AMD" ... meaning the real benefit would be for AMD gpu's not nVidia
Not true. Yes, FSR is indeed a technology developed by AMD, but it does officially support any Nvidia card from the 10xx and 16xx lines and newer. FSR is part of AMD´s GPUopen program, the Source Code for it is entirely Open Source, If it had anything in the code that would make FSR intentionally slower on Nvidia cards (or faster on AMD ones) it would have been called out by now. AFAIK FSR in implemented at the shader level, the limiting factor would be a given cards general shader performance.
Fsr is opened sourced homie. Meaning not just amd but also nvdia and even Intel arc if they wanted
