I recorded test gameplay here and here.
What I got were really bad stutters/freezes/disconnections every 10-30 seconds (both display and controllers), with great performance in between: perfect latency and clarity/resolution. Also, there's a bug in the menus where only touching the trigger registers as a click instead of actually pulling the trigger, as yayameowmeow mentioned. Arguably the performance is not usable, but it still boots and runs, I would just suggest using ALVR instead until it improves.
