Ralf – thanks. I sent you a few, we had talked in email, I reached out here to see if any community folks had an idea.
The issue is exactly like you say. If for testing I switch the mode to “Generic 3D Display” I can then of course get the FO76 VorpX menu inside the game etc but not in the actual HMD.
It looks like it hooks ok but the HMD does not show FO76. It does not happen with anything else except FO76 that I can see, I’ve tested other games. I am really sad since VorpX is great and I want to play FO76 (even though it’s a dumpster fire, yeah yeah) in VR.
