Ok. Seems easy enough. Cheers.

It is simple and gives a good performance boost. You clearly have a deeper problem if you haven't seen a big uplift since your upgrade, sorry I can't help further.
Thanks for your help. Any is appreciated.
Hi . Now up and running on Openxr / open composte. This has helped a lot. Visual’s clearer, more stable altogether.
Replay also stable now. Just got to figure out how to stop the audio switching when I go back to desktop. Has dropped the Main T in Asseto Corsa fps app to 92 instead of 98-99 as was before. Not sure if that should be lower though. Thanks again for your help.

Quest 2 + Windows 10 --or-- Quest 2 + Windows 11 ??
What's the current assessment? Have the Windows 11 issues been fixed?
It might have been an Oculus app issue, but not sure?
I'm Currently using Windows 10. It works, but I still haven't investigated why I'm only getting 45FPS with a RTX 3070 Ti--note that this gaming system has an i7 7700K and a Z270X-Ultra Gaming-CF MB (DDR4 4130 2x8GB), so maybe it's a bottleneck issue.
I'm getting a 3090 for my new-being-built-next-week workstation PC for 3D modeling and animation. I wonder if a 3090 would be bottlenecked on my gaming system, or if it's another issue that's affecting the 3070 Ti's performance in AC.

Does anybody know why my shadow starts rendering from somewhere around the steering wheel, nothing behind. 
I noticed this ever since I turned off "Smart shadow>Custom shadow matrices". But I really need to turn that setting off, because otherwise in VR every shadow starts flickering massively when I'm moving my head.
Edit: I tested some more. It happens in open vr and oculus vr mode. Tried different headsets. It doesn't happen in single screen mode.
If starting in vr and changing camera view (F7) the problem remains.

Hi, for all you out there using Quest 2 and getting 45fps with a beast of a pc/gpu :
this reads to me as being ASW turned on (this cuts framerate in half , 45 being exact half of 90.... )
Make sure ALWAYS to turn off ASW via Oculus Debug Tool (this setting does not save so you need to do it each time you enable PC Link !! )
And another great performance enhancing tip (for AC but also for all other race titles) :
In Oculus Debug Tool also, set FOV multiplier to "0.8; 0.4" !
You will render only 80% horizontally and 40% vertically, saving massive amounts of GPU performance, and in race titles it does not break immersion (on the contrary , you can imagine more that you are wearing a helmet and the limited FOV is because of that
)Here's a screenshot of the 3 settings I change each time right after I enable my Oculus Link:
cheers and happy holidays!

I just returned from my trip and tried these settings. I'm now getting 80-90FPS with pretty good quality settings.Hi, for all you out there using Quest 2 and getting 45fps with a beast of a pc/gpu :

The only thing I didn't like was the FOV-Tangent Multiplier at 0.8;0.4. I set it at 0.8;0.8 and the "crop" is barely noticeable, if at all.
I've also just tested it with the Render Resolution in the Oculus App set to max at 1.7 (5408 x 2736), and it didn't affect the FPS in AC very much, but the quality is wonderful with almost no aliasing issues.
Now I want to take the leftover parts from my previous workstation PC (BIOS flaked, MB dead), build a secondary PC for friends to network-race, install my older 1080 Ti in it, and see what kind of performance I can get with the same Oculus Debug Tool settings. Of course it's not as powerful as the new 3070 Ti, but it should improve performance some.

on a 3070Ti I settled at 80Hz and 1.5 render resolution...
Together with FOV at 0.8; 0.4 this allows me to run AC at almost all max settings (including any PP filter ) and still keep a decent amount of headroom to almost never drop below 80fps...
I tend to favour that steady fps over the occasional frame drop, so I aim at +- 50% GPU headroom, on a well optimized track with 5 or so good optimized cars as AI opponents (use the CM Analyse button to check the mods Triangle count esp.)
The clarity difference between 1.7x and 1.5x is neglect-able imho...
then again this is all personal preference. You may favour the extra fidelity and don't mind the occasional fps drop/stutter.
With a 1080Ti I would certainly not aim for 90 fps in VR, but rather 80 or 72Hz (and render res. at x1.2 or 1.3) depending on how much GPU headroom you have left.
cheers and happy fine-tuning!

Hello,
would you please help me. I can't get OpenXR Toolkit to work correctly.
I have installed OpenXR for Windows Mixed Reality and Net Framework 4.8.
Unzipped OpenComposite.zip and OpenOVR-openxr.zip into one directory. Launched OpenComposite and VR works. OpenXR Toolkit started, program font is green but no menu appears. Keyboard works.
This seems to be due to OpenComposite.
I have OpenComposite.zip and OpenOVR-openxr.zip. When I run OpenComposite.exe, VR works with the G2, but OpenXR Toolkit shows no settings menu in the game.
Does OpenComposite need to work with OpenOVR-openxr and how can I do that?

been fiddling with the g2 for years now. one issue i had was having ASW and Motion Smoothing both enabled. this caused performance issues.
the best performance increase is to turn PP off altogether. it will rouhgly double your frames and arguably looks clearer minus the effects. this would allow headroom to turn the g2s resolution to around 150% or more for some seriously amazing smooth visuals. rain and night will still work although rear lights wont be as easy to see.
if the PP filter really is a must and you want to still use steamvr theres a few options i can run through. one is to ensure ASW is set to whatever the motion smoothing setting is within steam. you can only do this as far as i know by using your vr controller with the headset on and going into windows vr settings.
ill retry the open composite method as above but if all else fails no pp filter and 150% + screen resolution with everything maxed at 90fps is hard to beat.

OK so just been doing a light test. Opencomposite and Openxr Toolkit. It's miles better even without reshade being installed. 90fps in dry and around 85-90fps in rain at Le Mans with a grid of 50+ cars. Seems somehow not to judder even during an odd drop of 70fps. In normal circumstances its locked 90fps in perfect clarity and a PP filter.
Game changer!
Not tried Project cars 2 as I never got it to run in vr with my old system. May give it a bash. Will definitely try ACC as again never been able to run it properly. AC is my main game because of the mods and community. It just keeps getting better. You’re running a good gpu though. Glad it made a big difference on your performance.Running a 3080. Tried it on ACC and Project Cars 2 as well. ACC was better but just doesnt compare to the other sims for VR. Project Cars 2 runs well however especially in the dry, going to have to start the career mode again

ok so I've been experimenting and reading. found a really good guide to tinker with a few things like foveated rendering and some custom ini files. basically the hp reverb renders pixels that you cant even see which causes performance loss. with your 4090 you should easily be able to run super sampling at 150% - 200%. Im going to write the guide up when I have a moment.
on a side note has anyone found a better pp filter than pure yet for vr? NaturalMod seems to introduce blurryness on latest csp/pure.

Hi. I have not tinkered with anything yet still on 100% on sampling . I’m not the best at changing things as it gets quite in depth
with some of the things that people can do. It would be good to understand better and what to do to give you the best performance.
I will look forward to your guide. Cheers.
