I got motion sickness when I was playing a zero G frisbee game when you were flying around. I did not get motion sickness playing ping pong. In fact, playing ping pong in VR feels as real to me as playing ping pong IRL. I am not a professional ping pong player though, because I'm sure they'd feel the difference! ;-)
As for using Immersed and using multiple screens in the app: no, no motion sickness at all either.
