I play SteamVR games, but on Linux, and without SteamVR, on a PICO 4.

The main issue I have at the moment is the controller offsets being wrong. Performance is fine, but the headset only records at 30fps.
I'll try some more games later on, maybe record them directly if I can get a mirror of the headset view.

Setup:
Fedora 41 (KDE Plasma, Wayland)
PICO 4 headset, connected with USB
WiVRN to connect to the headset and emulate SteamVR.
WlxOverlay for desktops and playspace drag.
PC Spec: AMD 5600G + 6600XT + 16GB RAM + everything on a hard drive.

Tested here:
The Lab - (working, loading screens look weird)
Zenith VR - (crashes after launch, broken loading screens)
Pistol Whip - (working post-recording, didn't wait long enough)
Until You Fall - (black screen)
Half-Life 2 VR - (launches but can't find VR)
Sushi Ben Demo - (working)

Tested previously:
VRChat - (working, world loading screens are broken)
Beat Saber - (working)
Tea For God - (launches, no hands, no playspace)
Resonite via Proton - (logged in, froze when loading cloud home. desktop mode works)

My build of WlxOverlay just has an edited watch layout and adds a VRChat OSC parameter for the headset battery when run in OpenXR mode. (building with OpenVR crashes since it relies on the Monado device)
