what is FOV? I have to sound like a nub but I can't figure it out.
FOV = field of view
It's measured in degrees, so 90 is 90 degrees, and that means you get 45 degrees to the left of center, and 45 degrees to the right of center on your screen at all times. (EDIT: Apparently in BC2 it measures up and down from center, not left and right.

)
Thanks Lego, I didn't know about this, and I remember hearing you could adjust it, but I couldn't find the setting, and I didn't really follow up on it.
I usually play on 90, but that's because that's the max setting on TF2, and now I'm kinda used to it. We'll see if it looks funny in BC2...
