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.
We’ll see ARM Steam before 64bit Steam.
Isn’t 64bit Steam Client due to drop for Windows imminently? They end 32bit support at the start of next year supposedly.
