I just got an Oculus Rift... the immersion and the depth of the world is really impressive(hills feel like hills in Assetto Corsa in VR), but I get motion sickness very fast. I first tried Dirt Rally and after the first slide through the first corner I had the feeling that my chair is sliding from under me, but 3-4 corners later I had to stop because of nausea and had to take a break longer than a hour before I could try to put the glasses back on. Then I tried Assetto Corsa(the main reason I got the Oculus), I didn't get sick quite as fast as in Dirt Rally but on Nordschleife I had to stop somewhere around the carousell.
Any tips that could reduce motion sickness, does the resistence to it improve over time? I already adjusted the graphics settings so I get 90fps constantly. If I still get sick from it by monday, I will return it.
