the difference is that all forms of "linking" currently just send your tracking data to your PC and then receive compressed audio/video output back, kinda like a low-latency livestream.
think of it like using that Steam Link thing to play a game that "runs" on your PC, while actually being streamed to your TV. there will be some latency as you may already know, and this is much worse in VR because you basically want immediate feedback on everything you do (especially looking around or moving your hands).
