I've played several hours of HL: Alyx now and have to say, it's been working really well. No major or regular headset tracking issues, no issues with getting the controllers to connect or stay connected, it all works great. My only two major complaints are: the controllers can only stay paired to one device at a time, so if you want to move it back and forth between your PC and PS5 regularly be prepared for a bit of extra faff each time. I also wish it had PC support for the adaptive triggers, I can imagine they'd have been implemented so well in the game and would've added that extra level of immersion.
If you have PSVR2 and a reasonably competent gaming PC, it's well worth getting the PC adapter for.
