to much culling to spare performance… read this:
Support for Wide FOV VR headsets (removing Frustum Culling issue) - Virtual Reality (VR) / Hardware & Performance - Microsoft Flight Simulator Forums
It was actually pushed so far that FOVs above 110 degrees are affected (Pimax, XTal, Star-VR, Valve Index)
With SU06 there were also first reports of the prob in the quest.
Interesting that it now also affects the G2. Do you use a comfort mod (other facecover or similar) to get 100 degrees in the G2?
