Hey, it's Matt from the OpenXR team at Microsoft.

NOTE: This message is only relevant to users with Windows Mixed Reality headsets (eg: HP Reverb, Samsung Odyssey, etc). It is NOT applicable to other devices (Oculus, Varjo, HTC, Valve, Pimax. Pico...).

We have pushed a new OpenXR Tools for Windows Mixed Reality version 112.2209.30002 in the Microsoft Store that will let you use the native WMR OpenXR runtime instead of having to switch it to SteamVR.

Make sure to install "OpenXR Tools for Windows Mixed Reality" from the Microsoft Store and run it. Then under "Preview Runtime Settings", choose "Use latest preview OpenXR runtime".

If you previously switched to the SteamVR OpenXR runtime, you can switch back to the WMR OpenXR runtime by either:
1) Run the Mixed Reality Portal, then at the top, click the "Fix it" button when the banner warns that WMR is not set as your active runtime
or
2) In the OpenXR Tools for Windows Mixed Reality, go to the 3rd tab (Mixed Reality) and click the "Set active runtime" button if it appears.

Thanks all for your patience.
