HP Reverb G2. When it works correctly I can play anything in 90 FPS.
If I open WMR and from the home I launch DeoVR I will get FPS somewhere between 1- 90.
If I open DeoVR directly without going through WMR and SteamVR I will usually get 90 FPS, but when I click the "Windows" button on the controller the WMR menu will come up and usually the FPS will drop to like 30 even after clicking the "Windows" button again to close the WMR menu, and if I open the menu again the FPS will drop more eventually to 0 FPS.
It doesn't matter what video or codec and it even lags in the DeoVR menu if I close the video. It happens only in DeoVR
