If you know how to mirror a display in Windows 11 I can try it in my sim rig and see if it works. I actually thought about doing that the other day for some reason, I think it would work.
It would be a super hacky way to just test, but you can do that with OBS set to capture the game output and then displaying the OBS capture. There's probably multiple other ways, but that would be a quick and easy way to test if you already have OBS installed
This didn’t work out, I crashed my PC somehow trying it with RFactor2 and AC a few times. Sorry to everyone who was curious like me, but in going to continue trying in the future.
