Even if I applied different settings it still limited it to 205mhz. My fps went down from a 80-120 fps to 10-15 fps, I exited the game to find that afterburner was limiting the core clock to 205mhz. However when playing COD MW2 today suddenly the textures became stretched, as if large mountain shapes were all over the map. The card seemed stable and only froze one time, this was a codec issue. The card performed much better and ran some of my games much more smoothly. People said that this was an ideal overclock for the card and lots of people where overclocking at higher settings. 3 days ago I overclocked my Nvidia geforce 540m GT 2Gb from 672mhz to 810 mhz.
