Game Skyrim Forum

idk what causing my FONV ultimate edition to have dropped frames after starting it. start out with 140 fps then after playing for about awhile goes to 60 t0 40 then much later to 30 fps to slightly under 20? i don't think it a mod or what? anybody got any ideals and i would link my mods list but im not sure how to. i have a AMD phenom ii quad core with 8 gigs of DDR3 ram and a nvidia gts 250 video card. if anybody can help that be great.
