I will also say that I've gotten significantly motion sick while playing the game. I'm not sure if there are some other things to change to help with this. I know what I'm in mini ghost mode that I get motion sick faster. Maybe if there was a way to fly that made it so you controlled the Z (height) axis instead of having to press space bar to stay at roughly the same hight could help. I think also some general smoothing of the map could potentially help as I think the bumpy terrain may cause some motion sickness.
