Their changelog on one of their last releases says
Added WinMR driver, it supports most headsets and controllers. Controllers can be connected both via host-Bluetooth and tunneled with the onboard radio chip. By default has 3DoF tracking, it can do 6DoF if used with the Basalt SLAM tracking software. Distortion is there but doesn’t work perfectly on all hardware, best results is on Reverb G2.
This isn’t really understandable for me as a VR newbie ;)
Edit: Maybe I’ll just get a Vive/Vive pro. They’re also cheap and probably enough to try it out without hours of hassle
Thanks for your explanation! Please let me know if you succeed with your Reverb G2.
