The wider FOV makes me nauseous. Setting the FOV as narrow as possible lets me play FPS games. It took me a while to figure out why some games made me sick and others didn't. Turned out to be FOV.
Interesting. I think I have the opposite issue. I try to get FOV in to 85 - 110 range. Otherwise i feel sick (or i need to sit far back from the monitor, which i can't really do on PC).
