Single 1440p screen? That is still quite CPU bound, assuming you have something like RTX 3070 or 6800XT.

Glad you enjoyed the video :) AMD will be releasing the 9600X3D soon-ish, which will be cheaper and more available. But if you've got the itch, I think the 5700X3D is a super easy upgrade.

Great to hear you gained some insight from the video :) I'd definitely get the monitors you want long-term. My suspicion is AC EVO will be GPU intense and un-optimized at the beginning. Triple 1440p will always be hard on the graphics card, but adjusting quality and resolution scaling can help. I'd recommend following the RTX 5070 series launch because it should pair well with 13600K. There are more X3D variants coming to AM5 later this year, so come 2026 that could be a good upgrade path for you.

@BenchmarkOdysseys thank you for the advice. I am waiting for the release of AC EVO. Let's see the real requirements .

X3D cache is a definite advantage to sims. Make sure you update your bios before installing the new CPU :)

Thank you dude!

Glad the video was helpful :) I used Valve Index for testing with SteamVR, and I bought fpsVR from the Steam store to capture the data. Your 11900K should NOT be thermal throttling if it has adequate cooling. Simulators like iRacing only really push 2-3 cores above 80% utilization, the rest will be below 50%. Therefore power draw is low. My 10600K draws about 60W in iRacing, while the 13700k is under 120W.

@BenchmarkOdysseys yeah there is something definitely wrong with the setup, even a simple session on chrome pushes that CPU to 100c and I got a Atmos cooler 360 on it. Changed the thermal paste a 100 times and nothing. Something just doesn't seem right. I just loaded up a replay after having not played it for months and now even in replay mode on my monitor it's doing 57 fps, when I first got this pc it would do 200 all day, but yeah the render bar is a solid red, so strange

@@ghost4004 What do you use for thermal paste? Are you sure the pump is working correctly? The pump has max RPM of 3200. If your mobo or software is manipulating its speed, it could be spinning too low, and not moving the hot coolant out of the CPU block.

@@BenchmarkOdysseys I'll check that, I didn't know about the pump, speeds, I do have a issue with the AIO pump it keeps reading that its spinning at 10000rpm so I'm guessing that has something to do with it

I do not run 3rd party apps like those because it adds layers of complexity. Maintaining a stable platform with consistent configuration is the biggest challenge with simulator benchmarking. It's an interesting topic, investigating the impact of 3rd party software. But the user's unique configuration of those apps, and how many they are simultaneously running, will influence performance measured. Same concept applies to ALL background apps, especially those irrelevant to the simulator. Those are often culprits to stealing CPU cycles and causing sim performance issues.

​@BenchmarkOdysseys overlooked test. Maybe not so important with 1ccd cpus. But with 7950x3d and the comming one its exactly what you want to know before you buy. Do i have an advantage while gaming while running background stuff. Would test only the common programs everybody uses like simhub, discord, maybe some chrome tabs.

None yet, but I'm looking into it!

I did the same, Hellhound for $800 shipped, absolutely loving it!

Thanks! I prefer the visual experience with my Index and using iRacing with the OpenXR launcher. Keep in mind that the graphics/replay options are stored within different ini files. So if you want to do a direct comparison between the two, make sure the settings are the same. OpenXR Toolkit has several options to tune settings. None of them are 'necessary' but it can dial in a few rendering options to improve graphics card performance (like fixed foveated rendering).

​@@BenchmarkOdysseys I do recall changing iRacing graphics for each runtime however it was long ago and I can't say for certain everything was the same. Are you also saying the OpenXR and OpenVR replay settings will be different? Previously would load up the same car/track combo and keep an eye on fpsVR. I see using replays is the way to go now. With VR Performance Kit it also adds foveated rendering which I have made some adjustments to maximize performance and still tolerate the resolution within the main part of my vision. I have wondered, and it seems likely, that OpenXR toolkit would be similar, possibly better if setup the same. When I initially tested, I don't believe I knew OpenXR toolkit existed which led me to believe that the best performance would be with OpenVR and VR Perf. Kit. Based on your experience I will have to give it another try. Especially since Motion Compensation for OpenVR is no longer in development where OpenXR Motion Compensation is. That is the primary driver of my curiosity in switching runtimes. Thanks for your reply and I'll be looking forward to more videos!

​@@Masty559 Ah I see! Yes, the replay settings are also saved within each ini. So if you're analyzing performance with replays I'd recommend reviewing those settings as well. The advantage to comparing results with replays is the consistency from run to run. Unlike 'real-time' runs against the AI, which can vary +10% between runs.

@@BenchmarkOdysseys Makes sense, thanks for clearing that up!

It is possible that I pushed too close to the limits of the 4080S. I can re-evaluate that scenario, and if I discover something interesting, I'll post an update in my next video :)

Thank you! :)

X870 does not provide additional performance (for the cost). The latest chipset does support faster DDR5 EXPO memory profiles. But keep in mind, the point of 3D V-Cache is to reduce data stored in RAM. Some top-end X870 mobos have additional overclocking abilities as well (at a significant MSRP cost and degradation of CPU life).

That's a reasonable conclusion!

I could disable 2 cores on the 5800X3D, bringing it down to 6. Then the only difference between it and the 5600 I have is 3D V-Cache and boost clocks.

@@BenchmarkOdysseys That would work also curious about 5700x3d

I'm not sure if Intel ARC B580 can do VR.

That'll be a massive upgrade, from 10th gen to 9800X3D. Enjoy!

Thanks :) 5090 will make iRacing bound to the CPU performance, even the likes of 9800X3D. You'd have to really jump the render resolution up to make the 5090 a constraint. Seems like 4090 is 30% faster than 4080S, so a 5090 should be +50% faster :S

@BenchmarkOdysseys Thanks, but I am asking about the Ryzen 9 5900X on the AM4 platform. I already own a 4090 and my system is already CPU bound.

@@Taz368 lol sorry! 5900X will perform a little ahead of 5600, because simulators cannot leverage 12 cores vs. 6. The Ghz boosting behavior of 5900X is slightly better. But it's still Zen 3 architecture without 3D V-Cache. You'll need to upgrade to AM5 if you want to push the 4090 to what it is capable of.

16GB of VRAM gives you a lot of flexibility with bigger tracks and lots of car models. I've seen the 7900 XTX go above 16GB (which is limit for 4080S). Crystal Light is high resolution and I'd recommend at least 4070 Ti Super 16GB if you want to chase high quality settings. But you should probably wait for RTX 50 series.

Ya that’s what I was thinking too. But the leaked 5080 rumoured to have 16gb VRAM only. Thinking if 4090 is better performance 🤔

@@ikeken19 It would be super surprising to see 5080 beat 4090 with architecture optimization and efficiency. It has -36% less CUDA cores than 4090. Maybe it can get within 20% of 4090? But 4090 only has 21Gbps GDDR6X while 5080 will be 30Gbps GDDR7. Anyways, sims benefit from faster GPU render speeds and can 'adapt' to VRAM constraints. I don't think 16b is a difficult limit to work with.

@@BenchmarkOdysseys so you would think 5080 > 4090 when it comes to VR iracing? Would love to see your review when it launches! Anyways good stuff you have here. Best reviews of VR benchmarks I’ve seen thus far!

In OpenXR toolkit On LeMans Ultimate and Asetto Corsa I use TURBO, it says turbo disables motion reprojection, don't know what it does but seems a good setting, works for me in simracing. OMG recently I had crazy experience, was playing VR simracing and in matter of second I felt dizzy and floating, very unvell could not take it at all, took my VR headset off. What happened is probably AMD crashed and gave just 20 fps or something like that. In game it looked like suddenly I floated in the car to one side, what made me almost throw up, immediately I pressed recenter and felt something is wrong as I had crazy motion sickness, tried to finish race but had to stop. I looked at PC and temperature was constant 30C not moving, I know AMD froze, it happened just once. It was absolutely not pleasant experience, don't want it to happen. I was surprised how some tech malfunction can take you out of line in split second I felt like my brain cooked! when I took VR headset off I could not understand what is happening as I was still floating haha

Are you noticing this in the headset? Or just in the data/graphs to analyze performance?

@BenchmarkOdysseys in the headset, for example, if Im 40mph and fixed my eyes to a specific sign or detail on track, it comes not smooth, looks like the "v-sync" is off... This kind of effects cause.. only in iRacing. I'm start to think is something related to the 6900xt

@@viniciusabdoracing Hrmm interesting. Looking at user reports, AMD struggle with balancing 'fixes' across multiple generations of cards. With the new series coming up next month, I wonder how much focus will again shift away from 5000 and 6000 series.

@@viniciusabdoracing I may be also experiencing this. When I watch replays too I see this almost.....dual image or delayed image that is not smooth. It is like a low refresh monitor that is trailing the image. I have a Quest 3, 7900xtx, 9800x so it should more than capable. I will continue to adjust and report back.

@@TorqueSpike40 for me, this issue happens only in iRacing, other titles is perfect smooth. Could you confirm if for you is just in iRacing?

Motion Smoothing seems to be unaffected by the recent update! Just make you don't trigger it too often :)

100%! The other VR software companies could learn a lot from streamlined, purpose-focused design of Virtual Desktop.

@@BenchmarkOdysseys yes and the less intensive CPU usage of a simple program. It's crazy how much more graphics and less latency you will have with just a simple program

@t.bartels5992 hi, are you sure ? pc link vs virtual destop, is VD win ? i ask because a have throttling in IR in VR with quest 3, whith a 14700K and 4090, medium detail in 90fps. I 'll try couple 7800X3D and 4090 same problem. 120fps same problem. I don't know why. but i kwow my pc can be stable at 90fps. I had try a lot of change and setup... 🤥

@@SMDC17.49 i have my vr glasses connected via cable to the pc and i use virtual desktop to connect. It works so much better i have a 57003dx and a 7800xt if im correct and i can do a lot on high setting 4x msaa with betweek 72-90fps even in start of races with full grids

Thanks :) 7800X3D may be hard to find. I like the idea of a 'drop-in' upgrade for 5700X3D. But if you are itchy for a new build, I suspect a 7600X or 7700X will give you a nice uplift from 5600. You'll also position yourself for future upgrades on AM5 into 2026 and beyond :D

I wish I had a way to really capture video of the image quality in the headset... subjective things are important with VR. If I can't measure the data points, I want to at least share the experience.

Have you tried AV1? It's very good.

Damn! That's lame. Perhaps you can toggle something (like async warp, motion smoothing, etc) and see if that makes a difference. Which Adrenalin driver version works for you?

​@@BenchmarkOdysseys looks like 24.7.1 is the last working driver. Before it would start displaying the infinite plane for a split second, then go black and throw DisplayPort errors

I got 5700x3d is amazing

Cheers! 7900 XTX has very compelling dollar-per-fps. Upcoming 9070XT looks to undercut it on price, but won't match it's raw performance.

@@BenchmarkOdysseys I'm definitely in the market for all of this myself - (wish I could find a 9800X3D for sale over here in the UK atm.) - but I'd prefer not to have to pay the nvidia tax :( Unfortunately it's been known for a while that AMD doesn't have the tech ready to compete at the top-end in graphics yet, but since I'm having to wait for the CPU, anyway, I'll also see what sort of price/performance their new graphics cards will have, even if a 7900XTX is probably the better option, anyway (since I'd like to play in VR too, though in the truck simulators, first :D )
