Blasaurus Nah you're confused, it doesn't work, just tried it. They surely made it easy now to install ALVR that's awesome, since yesterday (?) you can just download the app from the store. Then have SteamVR on a PC with a good GPU, install the ALVR client on the PC and you can run ALVR in your headset.
But like expected, passthrough does not work, surroundings are black. Only your arms/hands passthrough but that was already the case before of course.
