Hi simmers, been struggling to get the best out of the OpenXR tool, the reprojection wasn’t working well and had to set graphical settings to low. All that has changed with the revelation below that my Nvidia graphics driver installation was massively holding back performance - doing a clean install has improved matters no end.
I had actually discovered this by mistake as I was solving a random blanking out in VR while watching movies, so @zooze74 gave me some tips on clearing out my Nvidia drivers and that has changed everything.
For reference my system is an Intel 9900K @ 4.3Ghz, Asus 2080Ti, 64 GB RAM and I can get a solid 30fps with smooth visuals using reprojection and mixture of high and medium settings with 70% OpenXR scaling and MSFS scaling at 70% on the HP Reverb G2 and it’s looking pretty clear. Reprojection still has artifacts but it doesn’t seem as bad now and it definately improve frames, even without reprojection doing a clean install makes a significant difference.
Not saying this will work for you but if you have been messing around and are still unhappy with performance you might want to try the following steps.
Clearing out old Graphics Drivers
These are for Nvidia but should apply to AMD as well.
- From Add or remove programs type in nvidia and uninstall all drivers and applications. You might need to restart your system several times for this to work.
- Remove you graphics vendor installation directory I.e. for Nvidia the default was C:\NVIDIA.
- Open Disk Cleanup and select Clean up system files, check all boxes - ensure you check Direct X Shader Cache.
- Optionally remove any temporary files from C:\Windows\Temp and C:\Users\{USERID}\AppData\Local\Temp.
- Download and install your vendor driver. For Nvidia I used 452.06 as this was optimised for MSFS, more recent drivers have introduced a little more stutter.

Again thank you @zooze74 for the suggestion and tips for a clean install of the display driver. Thank you also to @CptLucky8 for the excellent analysis in VR. Also @mac2244 I hope this technique also improves reprojection with the OpenXR tool, before this change reprojection for me wasn’t even an option.
