Whenever I switch to 1st person (which I will do since the camera becomes a pain whenever I'm in a tight area), I've noticed that it's as though I'm looking through a cardboard tube. In fact, it's basically unplayable in that form.

I'm not sure, but I also feel like I might be suffering narrow FOV even in third person, although that could be discomfort from viewing the game in a box that doesn't fill the whole screen. First person FOV definitely feels low though.
