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.
Linux can be installed on any computer for free, so I wouldn’t call not making a Windows binary exclusive, unless all the games I need Proton to run are exclusive too.
If Windows users want to play Half Life 3 they can just ask Microsoft to make a reverse WINE lol
Sound logic.
