Meant to be Seen

I got Half-Life: Alyx running on the Steam Deck + Xreal Air glasses as easy as it gets:
- install the game
- install the HLA-NoVR mod: https://github.com/bfeber/HLA-NoVR
- install Geo-11
- set upscale to that of your device (eg 3840x1080 for Xreal Air)
- set Steam resolution to native

It runs quite smoothly, just some hang ups every now and then. Major issues are crashes after some minutes and some background objects with reversed stereo.

Would be nice to get a proper Geo3D fix for this version of no VR. It has directx 11 support

Try lowering in-game graphics settings like texture resolution or anti-aliasing. The Steam Deck might not be as powerful as a traditional gaming PC, so reducing graphical load could help with stability.

Iconic audience with 3D graphicsbasketbros. Really enjoyed doing the task. Each operation is coordinated. The unexpected experiments also made a strong impression.
