amdx2 dual core problems

[assas62]

I have amd 64x2 dual core, my game is fine other than when my char is running, the fps seems really bad, like the timing is of the graphics is off a little bit, the ground moves choppy, not smooth like on my older pc. I tried running on single core and nothing changed. my gfx card is inboard nvidia 6150 LE . any1 else have problem and know solution ? thx

when u are in-game, go to task manager (ctrl+alt+dlt), go to process, find Knight Online, right click, Affinity, uncheck 1 of the "core" boxes
