If your game is locking at a low FOV, I am not buying it. (many of us seems to get sick at low FOV, I mean physically sick).

Field of view is the simulated viewing angle through the camera, ie. perspective.

Every 3D game has a field of view angle. If the field of view is significantly different to what the eye/brain expects to see, it can result in motion sickness. This can be extreme, resulting in nausea and disorentation strong enough that play duration in excess of a few minutes can become impossible.

An appropriate viewing angle is usually 60 degrees for TV, 90 degrees for monitor.
