Something weird is happening. yesterday at releaseday the game ram crap low fps. 70-100 fps suddenly it ran fast +120 fps.. could play perfect with vsync on 120 hz. today im back at 70-100 fps.. something is fishy here. whats your experience with BF4 and SLI? I am running newest nvidia drivers. clocked my 670 gtx SLI at 1267 core/3500 mem. my 2500K is running 4600mhz. Win 8.1 and 8 gb ram.
