Hi I have amd athlon II x4 640, 4Gb ddr2 Ram, And one HD 6850 OCed. I run skyrim at 1920x1080 ingame AA and AF turned off instead 2xAA and 16 AF in ccc with some graphical mods. In wilderness everything seems okay with 40 -50 Fps. But in some heavy demanding sceneries and fights it begins to stutter and lag, So i checked GPU and CPU load in those demanding areas like MArkarth or so and my GPU and CPU load never exceeded 40 percent. Pls how can i fix it if its even possible. Other games like crysis 2 runs fine maxed out
