@Virus wish I could say I’ve had the same good luck. Still no VR slider on the launch screen for me. If you don’t mind me asking, what OS are you using (Windows 10 or 11)? My desktop, the computer in question, is a Windows 10 machine. Same issues as you described about. I’ve uninstalled/reinstalled Steam and SteamVR, same with Falcon BMS. Still no joy.
Strangely, I did the install on my Windows 11 gaming laptop. That one works in VR, but only using virtual desktop. Using a link cable with the oculus quest gives me an error, stating my quest is not using the same graphics card as the game. Strange.
