Things that are not needed:
--force_enable_VR
--force_OpenXR
OpenXR Tools for Windows
Connect oculus via link, start DCS Multithreading and tick vr in options. Nothing more to do
When steam link is active, configuration options are activated within steamvr settings. First two lines are in auto. Set to manual. 150 first, max the second one
Steamlink with manual settings. Bitrate 150mb, encode bar full right. No openxr toolkit (eats some fps), steam vr 200%, dlss quality. This is my actual quest 3 settings
