i played round a bit with different FOV values and settled on vert FOV 60 for 16:10x3. Funnily enough it made my gaming a lot better, my accuracy improved 5x as did my K:D :cheers
I set mine to 65 recently after playing for a while at a much higher FOV and I experienced a jump in accuracy and kills. The issue with this game is that the view models don't scale with FOV, meaning you'll be looking down your iron sights thinking you're dead on when in fact the iron sights should be drawn completely differently for you due to your FOV. You can see why this would lead to problems with aiming at higher FOV.
This issue was "acknowledged" by DICE but they also said "remodeling is difficult at this time" as well. :doh Even though this version of the game was supposedly developed with PC in mind, the fact that they didn't even think to do this gives me that console-centric feeling that so many developers have.
By default at 5292x1050, my FOV was 58, so I figure changing it to 65 isn't that big of a deal, but it does help.
