Rfactor2 The VR thread -settings & tips

BEWARE!! some people did the roll back without the blocked traffic, and when oculus updated back to v59. the rollback didnt work anymore!!!
Oculus/Meta hates these dirty rollbacks so i suspect it might be even intentional from them to try to prevent this after second update to v59.
I have experince of this shit from CV1 times.
So do not waste time. and remember to do the firewall blocks!!!!

And fuck you oculus!!!!

 

I know about openXR and performance increase also I know about the tools ;-) I used openXR and tools for reducing the "shiny" track surface on some tracks as known until - I think - mid of last year.

But I reacted that way and asked about SteamVR because I am running a 3080 with no probs using a Pico 4 and (yesterday) a Pimax 8kx with high details - so using a 4070ti (which is about 25 to 30% above a 3080) should not make any problems using SteamVR with the same settings just for testing ...

 

Yes runs OK for me in Steam vr too, but I liked the performance boost in open vr

 

Have you tried re-installing vcredist from support folder? E.g. PimaxXR requires latest vcredist as documented by the author - so maybe vcredist which is needed by rF2 is broken / has been overwritten?

 

No, im not aware of that at all.

 

Someone knows how use overlays (such Racelabs, SimHub,...) when using VR...???
Thanks in advance...

 

There are videos on Discord and it's explained, but having to launch them before starting the race is shit, if you escape it, everything is screwed up and you have to reload it, I already discarded it and Simhub is also out.

 

I remember that there is a documentation around from Oculus which shows to "stick" or "pin" the applications in VR desktop before launching application - but I do not remember where to find it ...

But it is less than a compromise.

 

so what's recommended then? waiting for Meta to fix v59 in a future update or just wait and see. STEAMVR launch with RF2 gives really average performance so I really need my opencomposite/openxr thing

 

i'd say roll back to v57.
but if thats not your thing (to do these dirty rollbacks) i suggest using vrperfkit to upsample from lower resolutions while in steam vr.
it gives bit perf boost without too bad drop in image quality.
do not use any of the preset values, they are too aggressive! 0.9 is pretty good multiplier

 

Have always used steam VR so far (pimax 8kx, 3090 rtx), but now want to try openXR. From what I read so far it is not that simple to set up. Is there a complete/simple/fast manual somewhere to get it working in rf2 ? Link is enough. Sorry if it is already explained somewhere here on this forum, but so far I have not seen it. Oh and is it easy to switch back to steam VR if the results are not ok? Thanks in advance.

 

From my point of view it is simple ;-)

As I am using Pimax headsets, too, I think openXR will not work or at least using PimaxXR will better to use. https://github.com/mbucchia/Pimax-OpenXR/releases

Just download the latest release and install it - the quick setup is also documented in the README.md of the git repo. I am using a 3080 and I have a gain of 3 to 5 FPS which is a lot when using VR headsets.

And yes, you can just switch between PimaxXR and SteamVR by just clicking the option (radio button) in PimaxXR - I think SteamVR needs to switched off while clicking or needs to be restarted.

edit: just to mention ... Pimax Client Software does make no difference to PiTool in my setup and I experienced a FPS loss while setting "fixed foveated rendering" to any value different to "1"

 

Thanks for the quick guide. 3-5 fps gain is somewhat dissapointing, but will surely try this later on !

 

I have done some quick tests this afternoon and the difference was 4-5 FPS using PimaxXR instead of using SteamVR (resolution (or whatever it is called in SteamVR) was set 100%).

If comes to VR I think it is a noticeable difference - if you are on screens then it is negligible of course (one would expect a difference of 20 to 25 FPS if changing GFX card for example).

I made a mistake concerning the option in Pimax Client (I have attached a screenshot) - sorry for that.

As I am using a 3080 I was able to reach 88 FPS at average while driving Valencia with 5 AI ahead of me at nearly full FX settings for every option (I am using triple screen setup most of the time and I am too lazy to change the FX settings even with stored profiles ;-) ) with the Pimax 8kx running at native resolution.

I changed player and opponent detail to low only and did set the override parameters in player.json to 3 for textures of player and opponent.

 

So thanks to @ColdBomb1 on the Open Composite Discord for the fix to enable Rf2 to use it again, worked perfectly in rf2, unfortunately I played with the settings and now get this error, anyone have any idea about how I might sort this?

 

Sounds like openXR is not running at the time the message / error occurs - maybe it is crashing the same moment you are starting rf2? Or just SteamVR? Or is it just a missing file (checked if re-installing helps)?

 

Yes, I think it was, all working again.

 

Hi.
Is anyone using Crew Chief with OpenComposite?
I'd like to show the TinyPedal overlays in VR.
With SteamVR works fine but with OpenComposite throws a dll error.

 

This is not possible right now.

 

FYI : Following a suggestion found elsewhere (DCS forum) I tried to disable OpenXrToolking and simply use the Openxr TOOLS options. (obviously this apply only for WMR headsets).
Then I applied FSR through RF2 Widget.
I can say that in my case the experience has improved a lot, RF2 timeframes dropped significantly: I can now achieve 90 fps butter smooth where before sometime it was a bit stuttery.
Maybe this could help others.
Openxr toolkit saved my life in VR but it seems that now less is more, and I can achieve more performance with less stuff running in background.
