I’m having a very similar issue as you. Everything detects properly and I start a game (BeatSaber) and about half way through a song my screen goes gray. When I take off my headset, the steamvr states that everything is missing (lighthouses, controllers) except the headset but the vive wireless software shows that the headset is paired. I have to close everything down and try again. But still the same issue. I’m kind of at the point where I might reimage the machine. I also noticed a slight ghosting effect while in game.
