For those unfamiliar with this, please understand because of the nature of the lenses and the way the VR system is pre-distorting the image rendered, you have to render at a different resolution than the HMD panels.
Peter Peterson, working at HP VR, is saying it is about 1.5x larger for the G2 (3164x3092 in WMR OpenXR):
Definitive Answer for the 100% Resolution Discussion [reddit]
Does this mean that if I put the slider at 1800x1800, the system is really running 2700x2700 per eye, or 5400x2700 total?
if that’s the case then it doesn’t really sound like VR rendering is very different from 2d rendering performancewise, there is just so many pixels.
