The game is way to annoying for me to play right now cause i keep getting huge max's but annoying min's no matter what settings i use...from Ultra to high..even drops while on medium
I've unparked my cores, OC my cpu to 4.2 ghz and still get drops from 60-70 fps down to low 40s and really makes the game feel choppy and just not smooth
my average and max fps come out to be good but the problem is the minimum fps i get in bigger maps with more players (operation locker only map that runs perfect)
i heard that windows 8.1 utilizes the cpu a lot better and gets rid of the really low mins
3570k 4.2 ghz
7970 ghz 1125/1600
13.11 beta drivers (newest)
Beta drivers could be the problem, try some final drivers.
Also yes windows 8.1 will improve the fps you get.
