FSR for OpenVR

@NuScorpii Are you the guy writing OpenComposite-ACC? If so, should this work for native SteamVR devices like Vive-Pro or Valve Index and is it likely to work for AMS2?

 

Wow - this is a game changer for my sys

I can run my G2 at 105% steam SS (which is really about 200%)

Settings
Track Ultra
Cars High
Grass Med

These are the other tricks for me
Turn off mipmap negitave bias in the FSR cfg - limits the flicker
Run shadows at low - this limits the flicker and looks better
Run AF at x8 (not x16) - again limits the flicker and due to the super sampling there is no loss in visuals

I also run the sharpening in the cfg file @ 2.3

For the first time I can run a rain race @ 90FPS

Simply wonderful mod

 

What do you mean with: 105% SS is really 200%?

 

The native resolution of the G2 is 50% SS in SteamVR. So 100% SteamVR is actually 2x Super Sampling (200%) for the G2. Anything over 50% is a higher SS for the G2 in SteamVR.

 

That’s not correct. 100% is correct in steam VR due to barrel distortion. This was confirmed by HP when the G2 came out. There’s a couple of vids on YouTube about it. Karl Gosling did one.

 

I haven't noticed it when running it below 100% and I know what barrel distortion looks like. If you ever did the GearVR lens mod on a HTC Vive or Vive Pro you'll know what actual barrel distortion looks like and the G2 doesn't have that. Regardless of what has been said on the internet I disagree there is any barrel distortion at resolution lower than 100% and if it is there it's imperceptible to the average user. If you can actually see it kudos to you.

 

I have to run DCS at 65% steam SS (so more than the native 2160 x 2160 per eye) and notice no distortion at all

 

Mike is right fellas - it’s not that you see any distortion, it’s just due to the fact that you need to render an image higher than native 2160 (steams 100% is approx 3100) so that when you stretch the image across the ‘pincushion’ (by making it a ‘barrel’ to counteract it), the stretched image is still effectively still at native resolution in the middle of it.

There’s plenty of videos and write ups to validate. Running anything less than 100% in steam is downscaling due to the barrel stretch.

Turning shadows completely off looks the best to me. Cars still have shadows but no more flicker chaos on the track from objects around.

 

well.... the game crash on me... default settings.....WMR / G2

 

Yepp! Same happening with me. I re-installed the original openvr.dll after i set up win11 clean again and now it runs.
But from my perspective there is NO change in fps with the fsrperfkit.
Its a little annoying but thats life i guess.

 

Chaps - check the doc linked in my sig and the mod in there works.

 

I know this doc. But the fsr-tool is still not working. No chance for me. I measured with and without. Its placebo….

 

What headset? Works on my G2 in SteamVR but the mod isn’t for oculus

 

Sorry, got it finally to work with the version 1.1. i think the fsr_easu and fsr_rcas file are important for it to work, since they are missing in the newer version which does not work.
Thank you very much Rob Davies!!! So happy with my G2 now!

 

Great stuff. Yes, holgers 1.1 version was adapted by nuscorpi to work with AMS2 as it’s an old version of OpenVR. He hasn’t the time to do the change work with 1.2 unfortunately.

 

I heard that Holger wants to adapt the VRPerfkit for AMS2. Apparently he‘s already working on it! We should support this guy! Does anyone know how one could send him a little tip for his work?

 

Check out this post regarding OpenXR:
OpenComposite OpenXR

Am I understanding then we'll have OpenXR and VRPerfkit to play with?

 

Sorry for the dumb question as I did just read thru the complete thread. Got to the end and see a note that this does NOT work with Pimax. I have the Pimax 8KX so it is true this does not work ? If it doesn't can anyone here recommend any other method to improve the frames/sec on Pimax because the Parallel Projection needed on the pimax is a ball terror !

 

You're in luck. The OpenXR toolkit dev has built an OpenXR layer for Pimax. Still in beta, I believe, but working on a bunch of games.
