Hi,I had massive issues with my quest 2 and i will try to help.
Not sure about your specs, i run a 12600kf with a 2080ti and 16g of ram.
Windows:
-First make sure you are on win 19044
-Game mode and hags ➠off
-power plan ➠ Maximum performances
Nvidia:
-Update the drivers to latest or previous using DDU with safe mode .
-Nvidia control Panel / 3d Settings / maximum performances and i leave the rest on default.
Now the part that worked for me and did not do before contacting Oculus.
-Disconnect every usb device a part for keyboard and mouse
-Disconnect from internet.
-Boot in safe mode (Msconfig/boot/safe mode) and uninstall Oculus as well as OTT9Oculus mentioned could create conflict.)
-Check for Any Oculus folder and remove it ( Appdata / Document or any location you might have).
Restart in normal mode (Ms config/Boot/Normal mode/restart)
I run it in 72htz mode at 1.0 in Oculus non beta ASW auto (i prefer bon beta) 100 scale in game and 80 for lod and obj details.
Link and Air Link both fine ( I prefer Link, less compression).
The rest will depend on your system really but hope it helps
Instructions where given to me by Oculus support but did not mention any specific game.
Since this i can fly on DCS and MSFS with a really good experience.
Just to stay on safe side, remove MSHS module from community folder.
Been asked by support to remove MSI Afterburner as well but tried it since and not issues so far.
Let me know how it goes, worth a try.
