Thank you for the quick response! I totally get that this will take time, and thanks for looking into it. I've actually never gotten motion sickness from this kind of flight game before, so my experiences definitely aren't universal here.
I fly with arcade controls off and need the locked camera to actually control my flight, which is probably a big contributer and I should have clarified in the first post. In that mode the camera sways a lot. Also when walking while riding Red, the camera bounces a fair bit. Those too motions definitely made me feel a bit light headed.
I also think mounting/dismounting can cause a big fast swing which is mildly disorienting. I don't think on its own this is a big issue, but compounds with the smaller motions.
