Native HMD OpenXR
For owners of headsets from Varjo, Pimax, HP and possibly others too their native OpenXR runtimes are not working correctly.
Currently the only way for us to get the game running is by switching runtimes and this is sub-optimal for performance. For me using a Pimax Crystal this can result in up to a 20% loss in performance. This also requires a dance of option changes between the different apps I run just to get WRC working and to get everything reset after use.
What I would hope is for OpenXR to not be specific to just Steam and Meta. Everything else I run that is OpenXR based works as expected with all OXR runtimes and layers.
For what it's worth here are my findings trying to use the native runtime for the Pimax Crystal: The game will start and menus etc in the floating theater show correctly, this actually runs 90fps compared to Steams XR which can be around 70fps and stuttery in this mode, native is far better for these theater modes. When a stage is started the hmd will switch into stereo 3D BUT will flicker between eyes and not react to head position movement with what looks like a window within a window.
