40-70% and 80% for women sounds insanely high. I got a used HTC Vive to have beat saber parties with people and so far none out of about 20 people have experienced nausea even with heavy drinking.
Yeah, I would say there are definitely specific experiences you could make that make 80+% nauseous(I have pretty good VR legs but moving platforms can still disorient me). But a well designed VR game accounts for that, see something like Beat Saber.
This. There is a reason why I can play beatsaber without feeling anything. But instantly get sick when playing pistol whip. The level moving around me is just disorienting.
