Excuse moi, fov 90 would give you major fish eye!!!
Have you tried the 90 setting yourself???
FYI the FOV setting in this game is vertical value, not horizontal like TF2.
It's pretty much like BFBC2, so here's the link to figure out the right vertical FOV value according to desired horizontal FOV:
P.S. Default value of 45 actually yields 65 horizontal - major head aching tunnel vision
