Another thing I'd like to suggest if you could figure it out, is anyone with SteamVR downloaded, any game that uses Unreal Engine will automatically presume the game is VR-enabled unless you find where in the UE code is in the game and tell it that it is Not a VR game, every UE dev needs to manually turn off the option of it thinking its' a VR game so that SteamVR doesn't pop up every single time the game launches. You can't turn SteamVR off or it closes the game, it likely consumes resources by turning on even if not even being used.
If you could do that, that'd also be hugely appreciated.
