Is VorpX + OpenTrack the only way people have found to hack together a decently usable VR solution for BeamNG? How about other unsupported games? Has anyone had luck without spending the $40? Back before HMDs were affordable, I had a working setup in RoR using a Samsung smartphone running Riftcat /VRidge beta. Obviously, that would probably work today with a Gear VR, and supposedly Riftcat supports Occulus, Vive, and Daydream as well, but not WMR. I have a WMR HMD and, of course, it's already a process to get it working with many Occulus/Vive supported games, but they work very well. For BeamNG, the best I can get so far is by running WMR for SteamVR + SteamVR + OpenTrack for SteamVR and it's unusable. 2 fps and horrible jitter just in Steam theater mode. I'm going to keep trying different freeware and open source programs and see if I can get something working, but it's not looking hopeful for my wallet at this point.
