I myself am very sensitive to narrow FOVs and anything less than 90° I can't play comfortably, but the game is already at least 90 and it seems perfectly playable to me. I'll check this when I have time, but the problem with using extreme FOVs is that it introduces rendering defects: cut-off objects (weapons for example) and distortions.
Have you tried playing for an hour or so to see if you'd get used to it?
