I don't think I've ever heard that before. That sucks man. So many good First person games out there. You will miss out on Cyberpunk as well then which is probably the only game I look forward to right now. (even with Borderlands 3 coming out)
I've been feeling motion sickness too. Although most of the first person shooter I played in the past where on console. I don't know if the distance had anything to do with it. If it is I should go back to using the 20-20-20 more often.
