Because I tried to get rid of the splitcreen on the monitor, I messed up and changed the rendering api to OpenGL ES and now I cannot open the game anymore. I get errors mostly about scripts and materials not found in the VR.WAD file. Uninstalling and reinstalling doesn't work.

EDIT: Ok so I reinstalled my driver and I managed to launch the game from the desktop without opening SteamVR. Then, I changed the renderer from OpenGL ES back to the regular OpenGL. I closed the game and launched it from my VR Headset. Now I can play the game.

However, I have a question: How do I deal with the splitscreen I mentionned earlier? I kinda wished I could stream the game without people see 2 screens.
