Get Better VR Performance & Clarity With OpenXr OpenComposite In Sim Racing! 

Introduction & Set-up: 0:00 Automobilista Settings: 3:35 Assetto Corsa Settings: 6:03 rFactor 2 Settings 7:14

Wow, this is amazing - it made such a difference to both AC and AMS2, so thanks for sharing. Just as a heads up, I had an issue with the AMS2 in-game menus not appearing - and AC wouldn't show up at all. Apparently I wasn't running the most up-to-date version of OpenXR Toolkit, I downloaded it and everything was perfect. (Just in case anyone else has this problem.)

Thank you so much!! I have been struggling for days with steam vr. It looked horrible and blurry and this fixed everything!!

Thank you, this is amazing! I went from choppy frames to solid 60-90fps on ultra, 4K, with SOL on, and it even leaves some room to experiment with recording in 4K!

Thanks for sharing this video! Im testing VR for 3 days now on my system. I got AMD5900x, 32Gb ram, Nvidia 4080rtx. I got exact the same performance from SteamVR and OpenXR. The main difference for me was turning off HolograhicShell in windows. Especially for win11 users. I gained ALOT fps!!. It was 90fps peak, but really choppy with drops. Now I got everything maxed out, 89.8fps average. You simple can turn HolographicShell off to stop the process. "Go to Computer Management → System Tools → Performance → Data Collector Sets → Event Trace Sessions. In this list, find HolographicShell, right click, and choose ‘Stop’."

Long story short...I chose the G2 . Thank you very much for posting this vid. Subbed and liked. Nice work m8...

Thanks for your video its so easy to understand looking forward to trying it out in AMS2 WOWWWWWWWWWWW I tried i racing its absolutely awesome Open XR has got me around 12% on fpsVR Thanks PSR

Yours is the third or fourth video on OpenXR/Open Composite that's swum into my RU-vid feed in the last couple of days - so I went ahead and did it all about an hour ago. This is a huge improvement over SteamVR. Not only is the centre IQ improved, but the 'sweet spot' seems to have expanded considerably, expanding the useful FoV in the process. I'm more 'in the game' than I have been to-date. I'm on a more modestly-specced rig than yours (RTX3070, Ryzen 5 3600) so I've found in Assetto Corsa that with Rendering Settings = 100% and Motion Reprojection = Disabled, the experience is not good. Jerky and stuttery. With Rendering Settings = 100% and Motion Reprojection = Always On, it's much smoother. But...because I decided to go for a lap of Fonteyne I put myself into a '62 Lotus open wheeler, and noticed that the front brake lines and the leading edge of the tires took on a weird shuttering motion (like a flip-book) as soon as the car started to move. That went away at Rendering Settings = 75%. With Motion Reprojection disabled I got 90fps. The few frame drops bugged me though, so I put Motion Reprojection back on, still get 90fps and it's much smoother. Even at 75% scaling this is much better than SteamVR.

Thank you for posting this video. I have watched a couple of your videos and it is apparent you are trying to help your fellow sim racers. Appreciated, subbed

Awesome and Upload my friend and thanks for the Tutorial Full support here and thumpsup and more power to your channel

From my understanding if you select "opencomposite" you can select "launch in steamVR" and it will still be running in opencomposite. I never tried "launch in oculus" even though I use a rift s. Anyway, I'm getting a G2 V2 for Christmas BUT I'm still using a low end card (2070 super) but I'm sure I can manage to get her running okay. Great help here btw thank you.

Just got my G2 yesterday and i hated steamvr on my rift s. Managed to get it working ok but had to turn it down. This seems to have helped and is the easiest guide I've found. So thank you sir. Much appreciated 🙏

Gonna try this for RF2!! Getting into that more than iRacing currently

Thanks a bunch mate!!!

nice improvement! thank you ! I tried openXR 3 months ago but it wasn't good with a rtx 3060ti and g2, I switched to steamvr. after watching your video this afternoon I've checked the update and that's really efficient in ac and ams2. I was wondering about changing gpu but now I will wait until other software optimizations !

Just an update to this video. In the RF2 in a G2 with a 4090 I'm running at 125% Res in OpenXR with MSAA 4X max settings at locked 90fps with motion reprojection off. The card is immense.

Nice vid mate. Im really considering a used g2 but i know alot of user have been plagued with cable issues which has me a bit worried. How has yours held up for you?

Would be nice to see some FCAT benchmarks to show any actual performance difference.

So I had a g9 49 monitor and used it menus basically for over a year as I used my valve index for racing. ACC being so bad I could never use it properly in acc so I also just upgraded to triple monitors last week for ACC. Have you tried ACC on this yet? I'm just wondering on the % of performance gained avoiding steam VR. I've also got a 5900x and a 3090. Thanks for a great vid man. So happy to see people trying new things and helping others.

First, thank you for the video. A little confused on OpenXr usage, does this also run along with Mixed reality and SteamVR when using my HP Reverb G2 V2 headset? Right now just using Mixed Reality, SteamVR, and Revive. I recently purchased a RTX-3080TI graphics card - upgrade from my GTX-1080p. So learning a bunch of new stuff. Ok, you mentioned this works with Asetto Corsa, Rfactor 2, and Automobilista, but I have other VR racing games such as Dirt Rally, F1-22, the older Rfactor, Sports VR games, etc. Does this work at all with other games in my SteamVR listings??? I also use VORPX for older non VR games. I haven't gotten the download of OpenXr yet, just learning what it does and how it works. thanks for any information and your video.

Judging by msfs it could be really good. Will try for sure.

Great video, will a rtx 3080 10GB be good enough for VR racing games or is 10GB too low?

Have tried with RF2, motion reprojection do not work in Auto (it's like OFF) so, with you have below 90fps better set in always on Automatic is the better option, but.... Let's wait to fix this.

Thank you for the guide. One question, have you been able to use any overlay for rFactor 2 using openxr on your G2?

What is the difference between using this methode and the asynchronous Spacewarp in the Oculus Debug Tool?

I use airlink, does link cable make a difference?

Awsome stuff. When you do a change, is it so that you must switch the sim off and on again, before the changes takes place? T

in the AMS2 section you metion that it will run at 45 frames per second but it will look smooth to your eyes. How does that work? I just asumed if I was seeing my FPS lower then 90 FPS i am gonna eventually get motion sick, but are you saying that this set up the FPS counter isn't trust worthy for that? I am also getting 45 FPS on AC as well. What are you thoughts?

I get the openxr overlay only in virtual desktop, but sadly can’t get it to work with link cable.

Steam X-plane 12 and aero hmd no work. pops up: Steam vr was unable ti initialize, shared ipc compositor connect failed (306),error code (VRinitError_CompositorConnectFailed) i have the Sim race studio open xr installed? keeps popping up steam vr error when i push VRbox in xplane 12 settings

I’m now having an issue where it still starts SteamVR. It was fine for months. Not sure what to do.

Great and thanks for the tutorial. I ditched VR because of performance-issues I even had with a 3080 running just the Vive Cosmos. I've sold this shitty headset, but missed VR, so I hooked up my old Odyssey v1 and even with 150% SS, which is about the resolution the Cosmos was running on 100% I get a much smoother experience. Now I'm brave enough to buy the Pimax 8KX and hope that with a "potato"-FOV (they really call it that), low SS and graphics, 75 Hz I can run it without buying a 4090 the next day. I want one, but the prices seems to drop almost week by week and guess they might drop another 200+ € rather sooner than later if the coin-prices doesn't go through the roof again (which they could)...

thx this vid helps allot. what if i just am planing on buying the reverb g2, what exactly do i need to download? so far i think open xr and open composite, anything else i need to download? sry im new on pc

How can I stream on Streamlabs OBS using these settings?

used the app and ACC did not work. When I reset nothing worked. I reset each game the manually change the openVR_api.dll in each folder. Everything works now. There is a definite fps gain.

I installed Open Composite and Open XR, went through all the instructions. But when I run iRacing and AC, it still opens and utilises Steam VR, not Open XR

When using it with AMS2 and Motion Reprojection ON it is smooth but the picture get distorted, elements warp to the right and left and got some flickering. Playing with 110% scale on RX 6800XT and 3700X. This doesn't go away with lower resolution scaling.

rFactor 2 keep crashing when I load a track using opencomposit, anyone got a solution for this?

I have an AMD 5900x + RTX 4090. And SteamVR performed better for me on RFactor 2, about a 15% on CPU frametime. It's strange, in other sims OpenXR permorms better than SteamVR. Anyway I can switch easily between them with OpenComposite.

Can this be used with Project Cars 2?it uses the same engine as Automobilelista.

Was keen to try this as have HP G2 and AMS2. But I get an error in launching. It says opencomposite failed to initialise libovr -3001. It looks like I have the current version of openxr from the miscrosoft store. Do I need to leave this open in the taskbar. When you say you need to open openxr what does that mean exactly? I have use latest runtime settings On. Do I need to click on the OpenXR Runtime tab. Can I close the window? Open composite I just downloaded and extracted as you said and ran the exe and it downloaded the DLL. Frustrating. Do I need to do something in Steam?

I've managed to get opencomposite working on AMS2 and F122 only by manually changing the api file, the launcher won't work, but can't get it to work with ACC, it always goes to Steam VR.

Good night friend, my image is shaking when I look to the sides, freezing image in HP, in all applications, GAMES, DESKTOP... I removed the OPEN XR program, and everything went back to normal, without shaking. I ended up drawing the conclusion that the OPEN XR was the crash? what can it be? Thanks

Hi everyone, I need help with opencomposite menu in VR. I press the hotkeys but the menu does not display. I hane no clue why not. It worked only once but can't do it anymore. OpenXR Demo works OK. Any clue? tls.

I have used this running steamvr from ams2 launch, does it work like this or do I have to use oculus from launch?

SteamVR performed better for me on Assetto Corsa. SteamVR: 4ms CPU - 7ms GPU frametime OpenComposite: 5ms CPU - 8ms GPU frametime 100% scale, post processing disabled. RTX3070 laptop. HP Reverb G2.

no mention of fov rendering, thought that was a big plus with openxr

are you using csp in assetto corsa with openxr? cuz mines will not work if i have it active

this works good with halflife alyx .except i couldn't smooth turn and my ingame hands wir a bit off .anyone has a fix for that (FIXED IT )in controller settings .i had so many problems with jitters emand stutters ...alll gone now .smooth gameplay THANK YOU SIR

Works good but I have to crank the resolution scale in OpenXR tools to 160-170 to make AC look nice enough. Any idea why this is? Running a Reverb G2 as well..

How could I get more than 45 fps in asseto?

hy ! thanks i have a lot of shimmering, you have too ? (reverb G2) RYZEN 9 5900X RTX 4080, i try lots of differents setting but no find realy good solution .. Thanks a lot :)

The file comes up with a 56% threat score on hybrid analysis idk

Raceroom doesn't work with OC because it's a DX10 game and they refuse to upgrade to DX11. Same reason I've given up on the game since a long time ago.

Great video, very good SIMDID recently released a new formula steering wheel, it's great, the price is super discount, come and see

I’m probably doing something very wrong. Tried this för AC and it looks horrible. The image is really jagged and I had to go back to CSP version 1.60 for the game to even work with OpenXR. And also the sky is pitch black nomatter what weather settings. Using default PP filter and default weather didn’t help. Any suggestions?

I'm running AMD FSR upscaled to 77% or even 87% with custom render scale set to 50% on OpenXR but in VR my display is pixelated(aliasing) only on certain objects that are somewhat far away, like railings, the back bumper/spoiler of cars infront of me. I get 90fps upscaled to either 77% or 87% with custom render scale set to 50%, but it seems like the only way for me to make everything crystal clear and get rid of pixelated/rough/choppy objects or edges(aliasing) is to set custom render scale to 100% and the upscale to 100% but then I run on 40fps :/

Yep about to try this I crash anytime I launch a game someone's it works and steam VR home works fine I launch a game and it's all bad and my PC is pretty beastly 5600x CPU 3080 GPU 32 gb 3600mhz ram it's so weird because my CPU stays below 40% utilization and my GPU is between 60-70% utilization and it still crashes so annoying I've tried everything but this on e bright side when steam VR works it's incredible max settings and 60+ fps easy and sometimes a solid 90 when I tell it to

So, I have an i7 9700k Rog Strix 3080 and 32Gb ram. I'm struggling to find a way to get 90fps on my hp reverb g2. I have moting reprojection off. Should I put on? (i only play AC). Please help...I even have all the options turned to low like shadows and all the rest...

If I wanted to try it on ACC, do I also launch ACC in Oculus vr mode?

Is the link down? Have tried from two computers with different browsers 🤔

Why does AMS2 still open in SteamVR? I select ‘Launch in Oculus mode’. I’ve set up OpenComposite for AMS2, and it works fine with another game. G2. Any ideas??

Is this worth a try if I have a valve index?

Everytime i open games with OpenComposite i just get a desktop view in my headset. how do i fix that

honest question: can somebody explain why anyone would use this over the vr performance toolkit for steam vr?

This simply doesn't work for me. Followed all instructions to the letter and SteamVR is still opening when I launch AC (through CM). It is clearly NOT operating under OpenXR. Any tips? I've been going at this for days now and it's finally driven me up the wall.

I can no longer get Assetto Corsa to launch via rift for OpenComposite. OpenXR launches SteamVR even when everything is set for OpenXR? How can I fix this? Using Content Manager

On the Reiza forums they recommend starting in SteamVR mode. I did that and it works just fine (didn't try Oculus mode). I tested Open Composite together with the OpenXR Toolkit with Automobilista 2. I wanted to find a setup which gave me the best graphical quality during daytime racing while still being able to drive at night time. I use a very heavy track (graphically) for this test, Long Beach. I found this is only possible with motion reprojection on. The downside of motion reprojection is that it makes the image much less clear. Without Opencomposite and the OpenXR Toolkit I use 80% renderresolution to achieve this goal, but the WMR motion reprojection kicks in even during daytime races. With Opencomposite and the OpenXR Toolkit I can crank the resolution up to 90% (with FSR and 50% sharpening) and now motion reprojection only kicks in at night. So during daytime racing you get a very sharp and clear image! To manage this, I had to set motion reprojection to 'automatic' in the OpenXR settings (not the toolkit) and in the Toolkit to 'on' (not default, for some reason on default motion reprojection never kicks in). I use foveated rendering (50% 1/2, and 80% 1/16). Also I disabled the high res mirrors and set shadows to 'off' in the game itself (cars still have shadows and without the shadows there is much less shimmering). I have a 3080ti and a I7 12700K.

VR in ACC is such a nightmare but AC and AMS2 already work ok for me with Steam VR. It's too bad that this can't improve the performance in ACC!

So Assetto Corsa with openxr adds like a minute to my load time, is this normal? The performance increase is sweet by the way thank you

do i still use the ocu;us app?

Kept getting an error when I went to launch AMS. Downloaded openxr tools before launching. Would like to give this open composite try rather than steam vr

will this work with a quest 2?

Followed the steps for RF2 but didn't work for me. Not sure what happened EDIT: Got it working 😊

Will with work with the varjo aero

Does this only work for these games?

im using opencomposite with quest 2 and and i switch to opencompsite but the game still launches in steam vr

In AC I selected OpenXR, but SteamVR still opens up alongside WMR. Anyone knows why and how to stop?

is this still working? i dont see an exe file in the download.

How does someone who has a professional steering wheel interact? VR works only with cockpit view?

My latency is still high af

So you don't use the OpenXR Toolkit, as talked about here? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-saCS0rdLsc8.html

Strange you still need re projection on a 3090.

bruv, this is a vr sim racers holy bible right here i have not noticed any difference over oculus mode, but it helps with games that force steamvr on you right away. fuck steamvr. literally halves my performance.

why all these people recommend reprojection i cant stand the artifacts it causes id much rather a nice clean looking image and turn some graphics down if needed then be stuck in reprojection
