When you start the game in a PICO4 helmet, the "preparation" window appears and that's it. On the monitor, the game starts in a flat, 2D mode. This happens when you launch the game via VIRTUAL DESKTOP, STEAM, STEAM VR. How can I fix the problem?
When in virtual desktop, go to Steam. When you start AMS2, you should get the popup asking how to open the game. In 2d desktop, in SteamVR or in OculusVR. If you don't see that, you might have set the first option as 'always open in this' and you need to right click, go to properties and set it to always ask.
STEAM VR starts, the game logo appears there and the inscription "preparation", while 2D mode starts, and "preparation" hangs in the glasses
Start steamvr from the virtual desktop window inside Pico4 not on your computer. Start the game from the steamvr dashboard or via steamvr home.
Was testing a p4 and it works both with steamvr and VD I found convenient to use the GAMES tab on VD dashboard , maybe you should try this way
