Hi, so I'm running battlefield 4 on an i7 3930K @3.2Ghz, 2 GTX 770s in SLI, at 1920x1080. I'm running the game at the ultra preset. I average around 119-110 FPS. Sometimes I can play fine for a couple of minutes, sometimes it happens every couple of seconds, that my framerate plunges from 100+ to 10FPS, sometimes as low as 1! I have the newest drivers from NVIDIA (331.65). I've tried lowering the settings to auto. Nothing works, I'm losing my mind, the game is unplayable! All help will be appreciated, thanks so much!
