OVR Error keeps causing random crashes within MSFS2020

[cybhunter]

Within the last couple weeks, attempting to use the latest builds of Quest link (with Beta Channel enabled) with the latest NVIDIA Drivers on a 4080 has resulted in random video crashing

-What happens

Entering VR mode, when these crashes occur, the screen and audio will freeze for a second, with the audio then resuming, with the video frozen at the time of the crash. Attempting to move the headset around will create a tessellation effect.

Hey there @cybhunter 

Looks to me that there could be a number of things that could be causing this issue:

1. Latest Quest Link update with the Beta Channel operating could be incompatible or be throwing these errors.
2. Both the Quest Link's latest version and NVIDIA's latest driver update could be incompatible
3. NVIDIA's latest driver was downloaded incorrectly or file could be corrupted
4. If you are connected via cable, the cable itself could be the issue.

From what I see, Kernel error leads me to believe it could be a deeper issue, specifically could be an OS level issue possibly, moreover the GPU keeps sending broken frames to the headset which might lead me to believe it could be an issue with the GPU drivers itself, but it can be a number of issues really, some ideas I'd like to suggest you to try:

1. Do a full clean uninstall and reinstallation of NVIDIA GeForce Graphics Drivers
2. Check for any Windows or OS updates and update to the latest version
3. Reinstall Quest Link
4. Check that headset is on the lastest software version, V.69

Do note -> I'm not that well versed in these specific issues, but I hope this helps! 🐢

[cybhunter]

1) Just updated to the latest version (565.90) , no change

2) No system updates available

3) Have attempted this multiple times (including factory resetting the Quest Pro)

4) Currently running 69.0.0.576.352.641228209

If need be please elevate this to those who would be more versed in the programing

Hey there

Appreciate that you've tried those steps, if you could please send our engineering team a bug report in the meantime.

I will flag this issue to our engineering team so that they can have a further look into this issue. 

Thank you! 🐢
