I have geometry mode available , zreconstruction all that when running the dx9 game, but it looks flat. I was able to get the game to show in VR headset, and VorpX says its attached.
Hey, which Game is it ?
In a very tiny amount of Games you need to change to Fullscreen, or exclusive Screen via Alt+ Enter or in the menu settings.
For example in Hitman (2016) G3D and Z3D only works in exclusive Fullscreen, in Fullscreen its complete flat.
Maybe try that :)
