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.
The article’s title is ass, HL: Alyx already has a native Linux build. They’re working on an arm build.
That said, last I checked it’s generally recommended to run the Windows version through Proton instead, since it performs better that way. Maybe we could see that change?
