So, I’ve got VorpX working with the first couple games I tried. Works in Portal and Black Mesa, direct VR. I’m now trying Arkham Knight. I use the same process — Mixed Reality Portal is running but not SteamVR, I run the game, VorpX appears to hook, and the game opens with VorpX text on top. But when I put on the headset, I’m stuck in this dome looking at mountains and stars. Does anyone know what is happening?
Try to run the game windowed. There currently is an unfortunate bug where vorpX can sometimes lose connection to the headset if a game gets minimized (e.g. via ALT+TAB). Will be fixed shortly in the next vorpX update.
If that does not help, it might me a hooking conflict with some program your PC that also hooks into games. Portal and Black Mesa ar both DX9, Arkham Knight is DX11, so maybe there is something that gets in the way with DX11. The trouble shooting guide on top of this sub-forum has more details on the matter.
