Don't set location of OpenXR runtime with the registry, use OpenXR Loader Specs instead

I have the Reverb G1, it works fine as intended with WMR. I have the MS store version of MSFS, but I wanted to just try it with WMR for SteamVR plugin and the SteamVR runtime to see if there was any difference, and to be able to use FPSVR to see frametime info, and temps etc. When I changed to the SteamVR OpenXR runtime via SteamVR Developer settings, MSFS would launch SteamVR, even now with the WMR for SteamVR beta. I noticed that if I had the HAGS turned on, it would crash if I tried the Windows menu button. I meant to try it again after the new Steam beta with HAGS turned off again, but not have not, since the visuals did not seem as good. Hope that made sense…

Ah ok, I did not have Steam OpenXR selected in Steam, it was defaulted to WMR. I changed that and can now recreate what you and @CptLucky8 can do with SteamVR settings and FPSVR. Thanks for the responses!

That being said, the performance was atrocious! I didn’t change anything except lowering my render from 80 to 70 and putting the in-app resolution for FS2020 to 150% (the main resolution slider in steam is set to 50% since that is apparently the actual 100% representation for the G2.

Maybe @CptLucky8 can shed some light, but would using the steam openxr instead of the windows one be the cause of performance issues?

It is most likely causing some extra processing because you’re going though an extra hop. However, the OpenXR and OpenVR are quite similar and any “bridge” is only a thin layer in the end (it is not like translating OpenGL into DirectX).

What matters the most in the end is the final render resolution as it is determined by SteamVR SS + per-app SS and shown in the per-app video settings popup panel in SteamVR. This determines the resolution FS2020 is rendering to if FS2020 Render Scaling is 100% (at least this is how it works with the Index).

NB: you can see the render res and post process res using the FS2020 dev mode fps overlay in VR mode. It will be displaying this info on the monitor directly (just lift the headset to peek).

How can I switch back from OpenXR Steam to Oculus? In the Steam Settings there is no option any more.

You might want to read the pinned topic in the VR discussion which title starts with “Readme First…”?

I succeeded in using the regedit. Thanks for nothing.

A couple of questions.

  • How about performance with OVR toolkit? I would like to buy it to try to use windows, chrome, etc. during commercial flights.
  • Is the steamvr beta better than the stable?

im confused, i just got a g2 and have openxr install. what exactly am i meant to do?
