Performance in VR is a balance between FPS and world clarity vs being able to read anything on glass cockpit displays. Even on high resolution VR headsets like the G2 and Pimax, the screens can be difficult to see while still having a decent FPS. Meanwhile, the floating VFR Map panel can be shown in excellent clarity at the same time that VR render scale is turned down.
A second slider for glass cockpit clarity would help VR users so much. Turn down main % for world and up for glass for the best of both worlds!
