Left video is recorded from the Steam VR Mirror.
Right video is recorded from the Quest "Share" menu.

Here's my setup:
Virtual Desktop Sideloaded
Gainward 1080Ti 11GB VRAM
Mobo with 1Gb Network Port
Virtual Desktop (streaming)
SideQuest (for copying video and sideloading Virtual Desktop)
OBS for Recording the Steam Mirror View
kdenlive (for editing)
