There is no head bob or motion blur, but the FOV is 60 degrees, which is probably too low. I put a "dot" on the center of the screen to help with the motion sickness, but I didn't think about adjusting the FOV. I will try to make a new version with an option to tweak it freely between 60 and 90 degrees, and see if it helps. So thanks for your comment, it's very helpful, let me know if you have other tricks that could help.
