It could be a FOV (field of view) problem, try upping it to 80-90 degrees. Many games designed for console assume you are 10 ft from a tv, not 2ft from a monito

It could be a FOV (field of view) problem, try upping it to 80-90 degrees. Many games designed for console assume you are 10 ft from a tv, not 2ft from a monitor, so the default to as low as 60 degrees. I know if I don't up it to at least 75 I can't play for long without feeling disoriented, and I know some get headaches.
