I am a HP Reverb G2 owner and I just purchased vorpX a couple of days ago. I thought that vorpX supported OpenXR, but anytime I try to launch a game using OpenXR as my runtime I get a popup error telling me vorpX is unable to init an OpenXR session.
The only way I can get anything to work is to change my VR runtime to SteamVR. Is this working as intended?Dec 8, 2021 at 3:27pm #207789
You have to make sure that WMR is your default OpenXR runtime. The WMR portal should display an according warning message if that is not the case.
If your ensured WMR is your OpenXR runtime and the issue still occurs, something is wrong. Difficult to tell what, but in that case simply stick to SteamVR as a workaround.Dec 9, 2021 at 1:03am #207805CrunchyGlassParticipant
Want to add that “OpenXR session init failed” popup will still occur on some apps that used to work (Far Cry 5 / mpc-hc) since roughly the last quarter of November 2021. OpenXR is used by mixed reality portal and SteamVR also confirms OpenXR is being used.
The only way to run those apps is to set VorpX to use SteamVR.

I can give this a shot, but I am running on a very fresh (less than two weeks) Windows 10 installation. I have only tried a couple of games so far, so maybe I just got unlucky.Dec 9, 2021 at 11:45pm #207820
I’m getting the following error:
“OpenXR session init failed
This is a severe error. Make sure that OpenXR is working correctly on your pc or switch to a different vr api in the vorpx config app.”
Games load “as normal” with the vorpX logo but i get no output to the HMD, used to work all right but i started to get some errors so i falled back to the SteamVR api, then reinstalled OpenXR and this happened.
OpenXR seems to be working correctly, i can load the demo to test it works, it just won’t work with vorpX.Dec 9, 2021 at 11:47pm #207821
If yopu have trouble running a game with OpenXR, please switch to SteamVR in the vorpX config app on the ‘General’ page.Dec 9, 2021 at 11:56pm #207822
Nvm i just got it to work, didn’t realize i had “WMR for SteamVR” in beta, went back to stable and chose OpenXR in the developer settings of SteamVR and vorpX now works.Dec 10, 2021 at 12:06am #207823
Don’t set SteamVR as OpenXR runtime for a WMR headset! That’s pretty much pointless, OpenXR calls are just converted to SteamVR that way and then send through the WMR SteamVR plugin to the headset.
Use the native WMR OpenXR runtime instead, SteamVR doesn’t have to be running at all anymore with a WMR headset unless you encounter an issue with native WMR OpenXR.Dec 10, 2021 at 12:16am #207824Lawrence1962Participant
I had the same problems some time ago, and fixed it by re-installing steamvr and mixed-reality-portal a couple of times, until the mixed-reality-portal app asked me to set it as default OpenXR runtime.Dec 10, 2021 at 8:53am #207828
Oh, then i’ll have to reinstall everything :XDec 10, 2021 at 8:59am #207829
Normally the Mixed Reality app should ask whether you want to set WMR as your default OpenXR runtime when you launch it. Similarly to how SteamVR handles that.
Wishful thinking, but Valve should really just stop trying to force SteamVR as OpenXR runtime for headsets with native OpenXR runtimes. Totally confusing for any normal person.Dec 10, 2021 at 11:55am #207831
Seems OpenXR is now installed by default on WMR, oddly enough after reinstalling everything (twice) the OpenXR demo no longer works and it just falls back to the WMR Portal while vorpX keeps giving the “severe error” message.
If i make SteamVR handle the OpenXR API the WMR Portal does gives me a warning and a button to “Fix it” appears but even after doing it, no luck; guess i’ll try updating Windows tho i already have a higher version than the recommended according to the OpenXR documentation…Dec 10, 2021 at 12:37pm #207833
Just in case: make sure to close SteamVR when WMR is set as OpenXR runtime. It’s not required at all with WMR’s native OpenXR.Dec 10, 2021 at 5:22pm #207844

Ahhhh …. I think I see the error of my ways. I have always been starting SteamVR and then launching the game I want to play from there. Is the correct way to simply launch the game from the normal Steam interface and vorpX will automatically hook into it?
