Hey guys,

After having some issues with AA, I tried the forced AA solution with U3 engine, didn't work too well and went back to basic ingame AA + updated to 1.43 recently and ever since the game has been choppy. My system is as follows:

Win 7 64-bit
Intel i5 760
4 GB Ram
EVGA GTX 460 (768 vram one) with 275.33 Nvidia driver

my system isn't too fast, I know, but it appears I am far above the system requirements. I tried different graphic settings even on the lowest it ran choppy, whenever I entered le "free world" (caves, houses etc. weren't too choppy, still playable). changinge distance, detail etc. brought almost no change.

my CPU isn't even above 70 %, so I tried GPU-Z (no clue how reliable it is though)

memory and gpu use between 90 and 100 % (as it should be)
memory controller load never above 55 %m gpu temp at most 66 ° C/150 ° F.

I assume that there is some software prob, since the patch seemed to cause the trouble, however, I am biased (not willing to buy new GPU).

would be very grateful for any hints, solutions or similar experiences shared with me.

thanks in advance!
