I am a long time VR user of both X-plane 11 and MSFS. I’m only using MSFS nowadays (Microsoft direct download) and have recently uninstalled the Steam VR apps and fully updated all else (GPU drivers; BIOS; Windows 10 (Full re-install retaining files and programs); Mixed Reality Portal).
All is good with the MSFS VR experience as good as prior to the changes.
However, for reasons known only to Microsoft, I have never been able to load their OpenXR Tools for Windows Mixed Reality, in its earlier incarnation of Developer Tools or present version. It ‘installs’ but won’t run.
And now it’s worse. If I install it and don’t even try to run it, it prevents MSFS from loading (the blue bar gets around 80% of MSFS load up and then stops. If I then uninstall the App, MSFS loads up normally)
That in itself is not a problem to me - the github OpenXR Toolkit does work and I now want to optimise my MSFS VR using that. But, the recommendation is that, for the OpenXR Toolkit, you should start with 100% render value and Motion Reprojection ‘OFF’.
Can I assume (using the Windows resolution settings for the G2 at ‘recommended’) that the default state of WMR is 100% render and Motion Reprojection ‘OFF’? If so, then I have no need to worry about getting the OpenXR Tools for Windows Mixed Reality to work properly - I will just leave it uninstalled.
Any wise sages able to confirm?
Default MR is Off and default resolution is 100%.
However 100% of exactly what explicit resolution value that it has decided upon invisibly in the background based on god knows what is your next fun challenge!

Great - thanks for the prompt reply, @SimonJones7660
And yes - fully understood and agree

I don’t think that default is 100%, it’s rather calculated based on the amount of VRAM, below 100% unless you have more than ca. 12 GB of VRAM. It was recently explained by the author of the OXR Toolkit, I suggest checking the OXR Toolkit thread.

Ah - OK. That makes sense. But on that logic, presumably it remains the ‘base point’ for the OXR Toolkit to start doing its stuff. I actually do have 12Gb of VRAM so it should be an OK start point whatever, hopefully.
I’ll have another read of the thread. Thanks for your response!
I’ve been using OXR@100 until this past week. Depends on your card and settings I suppose. I was getting lots of stutters and fps reduction with OXR-100, DLSS- Balanced, DX11 and TLOD at 100.
I saw a suggestion on YouTube for Nvidia 2xxx and 3xxx cards to set OXR Development Tool around 110-120, in-game DLSS -Performance and raise TLOD to 120+ and other settings to your systems ability. I tried it, nothin to lose…Huge improvement for me. Greatly reduced stutters, much smoother too!

Great info, @KennyKanada
I’m starting back from scratch now I understand better what affects what in terms of the GPU/CPU interdependence. Your own tips and tricks are worth a try - I’ll let you know what impact they have (even though everyone’s system will behave slightly differently.
Thanks again
