Developer Claims Half-Life: Alyx Runs Standalone on Apple Vision Pro

Developer Udi Wertheimer says he got Half-Life: Alyx running on an Apple Vision Pro M5 with no PC and no streaming, at 3K per eye and 60 fps "smoothened up to 120". He built on Valve's September 16, 2026 ARM64 port and the open-source Klepton compatibility layer. Nothing has been released, and neither Valve nor Apple has commented.
