Am I the only one who thinks the motion sickness is something good? Like, "it feels so real that you get motion sickness" and that the new version feels less realistic. I hope I'm wrong though!
Recently read a great working theory of motion sickness... when your brain can't reconcile your sense of "down" or motion via your ear and your body orientation with your vision's perception of down or motion, then your brain thinks one or the other is hallucinating because of something you ate, and that's why you have a nauseous reaction, to expel the poison.
I don't get motion sickness moving through the real world, do you? Should have that checked out. There for motion sickness in a virtual world does not seem more real.
Realism isn't always good. Thinking that motion sickness is good just because it's realistic is like thinking that the ultimate VR experience will cause debilitating pain whenever your in-game character gets shot. Some experiences are better left out.
Even a slight delay between your head moving and eyes seeing a reaction can cause nausea
