The Short Version
Valve added Steam Link support for Apple Vision Pro, letting users stream PC and Mac games wirelessly at up to 4K, though VR games like Half-Life: Alyx are not supported yet.
Apple Vision Pro costs $3,500 and has spent most of its life looking for a reason to exist. Steam Link gives owners access to their existing PC game libraries without buying anything new. The catch is : you get flat, 2D games on a big virtual screen, not the full VR experience the headset is physically capable of delivering. Valve left the door open for true VR support later, which means the best version of this is still unfinished.
