It is now almost a year later but it is finally possible to play this game again since Rockstar updated their Social Club sign in process. Therefore I can now recommend this game. Just make sure you use the streamer app or cable that came with your headset because Virtual Desktop (at least with my Pico4) gives me the same error that Hitman gives when I try to go into VR mode. Also: SteamVR thinks my Pico4 is an Oculus device but when I set SteamVR to XR mode that isn’t much of a problem...
