I never felt sick from just VR, but the continuous movement (rather than teleporting) made my brain confused like I wanted to fall over, but after a few hours of it I got used to it for good and now have no problems with VR, other than fatigue of moving around so much aha.
I think most people could break it in, but are reluctant to keep playing or play again once they feel sick doing it. While its easy to get immersed, you have to disconnect yourself from it a bit and remember you are in the real world, when friends and family try it I have to make sure they dont walk into walls, but on my own I have full awareness of my surroundings even when I am blind to it. It just takes time to get used to it.
It’s a really fun experience, I hope it keeps getting developed regardless of sickness issues. Higher framerates are definitely important, the 120Hz mode on the Index is definitely recommended, any lower and its much more likely to be sickness inducing.
Nononono, UX is fucking terrible at the moment, if you said this somewhere like 10-15 years ago I would probably agree with you, but everything is designed to serve ads and be as functionless as possible these days.
