so i've been playing this game for a couple days now, and i have the 1.6 patch downloaded, but i'm still getting a pretty bad framerate and my screen stutters way more than it should considering my rig is more powerful than the recommended specs. i have a nvidia gtx 850m, 12 gigs of ram, and i can only play this game on medium for it to be at maybe 30-40 fps. i can't even get a fps counter to show up on the screen (i've tried changing the option in the gamer profile).

i've tried a bunch of fixes - i've changed the performance settings in nvidia's control panel, i've changed the GPU max buffered frames and 'disable loading mip' options to 1. i don't understand, i should be able to play this game on at least high, but it stutters like crazy. does anyone have any ideas?
