I’m getting an error at launch:
OpenXR instance creation failed.
This is a sever error. Make sure that OpenXR is working correctly on your PC or switch to a different VR API in the voprX config app.
This is with or without ‘WMR developer preview runtime’ active.
vorpX will still start up but when I run any game, although I see the vorpX logo, my G2 headset display remains black. Tracking and audio work but no display.Apr 14, 2022 at 2:50pm #210638SolidpointParticipant
I fixed my issue by reinstalling the latest Nvidia drivers as a clean new install (deleted all profiles and configs)Apr 19, 2022 at 3:00am #210677MinabeParticipant
Best thing you can try is to reinstall everything, from vorpX to the WMR Portal to even Windows. I had that same error and reinstalling everything fixed it (with mixed, never reliable results) until reboot, ultimately i changed my WMR for a Quest 2 and everything worked perfectly out of the box and i couldn’t be happier, truly a world of difference and my recommendation for your case.Apr 19, 2022 at 3:47pm #210680DirtyTecParticipant

Did you use display driver uninstaller? Or Windows uninstaller?Apr 21, 2022 at 2:07am #210698MinabeParticipant
When installing Nvidia drivers you can just check the “Clean install” boxAug 14, 2022 at 3:59am #212729rich0550Participant
No problem here with WMR and HP Reverb G1, latest Nvidia studio driversOct 18, 2022 at 7:36pm #213408jjenssonParticipant

That’s good to hear. I ordered a Reverb G2v2 yesterday, because i’m fed up with Quest 2 and the whole wireless friction (cable link gets worse and worse, it seems they’ve abandonded it).
But what do you mean by “studio drivers”?Oct 19, 2022 at 11:00am #213420RalfKeymaster
Every few months nVidia releases a driver that is more rigorously tested against professional graphics applications than the usual ‚Game Ready‘ releases. They call these ‚Studio‘ drivers. Don‘t quote me on that, but I‘m almost 100% certain that there is nothing special about these releases except from the additional testing.
The Reverb is a good choice with vorpX in mind BTW. The WMR OpenXR runtime is quite a bit better suited for vorpX‘s multithreaded rendering approach, i.e. you will experience less situations where the runtime drops the headset framerate to half with little or no reason compared to Oculus.Oct 29, 2022 at 1:33pm #213548BorvathParticipant
There is an important information about the future on WMR OpenXR runtime for the OpenGL games.
WMR OpenXR runtime will support Vulkan and OpenGL in the future.
“Hey, Matt from the OpenXR team at Microsoft here,
The WMR OpenXR runtime currently has support for both DX11 and DX12, and it will have both OpenGL and Vulkan support by the end of the year. This will be for both 32-bit and 64-bit applications.
Meanwhile you can use https://github.com/mbucchia/OpenXR-Vk-D3D12 as a stop-gap solution for both OpenGL and Vulkan (but 64-bit applications only).” (mbucchia-msft, 26.10.2022)
