Finally tried Air Link, the Quest 2 wireless link that allows wireless pcvr.
It was a very minor faff to get the pc paired over the network (pc wired over power line upstairs, Quest 2 over my Wi-Fi 6 network in the living room, downstairs). Very impressed. I accidentally ran it over 2.4 ghz and that was deeply unpleasant. Once I connected the quest 2 to the faster channel though, it was pretty close to the experience of being wired. They were at the furthest extent possible from each other. I was fairly close to the router though.
I didn’t experience any lag, I didn’t even notice any visual artefacts. If I didn’t know, I wouldn’t have said it was being streamed across my house. This is playing Alyx, which is a good looking title. I’m quite excited by this, as I have way more room for standing vr downstairs than I do anywhere near my rig, where my PC actually is.
