TL;DR: Valve launched the Steam Frame VR headset with an Arm-based Snapdragon chip, aiming to run Half-Life: Alyx natively and streamed from PC. The new hardware features a “Frame Verified” status for optimized games, while rumors suggest two upcoming Half-Life titles supporting PC and VR cooperative play.
I played it with ALVR on Linux with a meta quest 2 from start to finish like a year ago. ran like a champion (ok, it froze like every 3 hours, now that I think of it).
