My vertigo mainly occurs in environments such as "Half-Life" (including Portal) and "Haydee". I also have problems with excessive light and gravity, such as "Alan Wake" and "Severed Steel". Most of the time, it will be better if I turn off motion blur, turn off head shaking, zoom out (or sit farther away), and turn off light and halo reflections.
In addition, I seem to be allergic to electronic sounds. When I was a child, I would get headaches if I played NES games for a long time, but SNES was much better. What puzzles me is that I actually get vertigo in "Eversion"...
