I bought a Vive Cosmos in February and I think I'm just going to sell it. It is so fucking unusable unless you are standing perfectly still and facing an incredibly bright room with multi colored walls. It's fun for like a minute at a time, but then I'll turn my head or god forbid try to crouch down and pick something up, then I just get ass fucked with tracking errors, have to spend 5 minutes getting it tracking again, only for it to happen again 2 minutes later. It is so fucking unusable
