You've all probably heard of this problem but I've looked for a solution and none of them have worked so far. I decided to download the Call of Duty 4 demo before buying it and no matter what I do, I get a lot stuttering and low FPS after the first 5 seconds. I've tried disabling Sound EQ Filter, enabling multiple GPU and dropping all the details to as low as they can go but I still get the same amount of FPS and stuttering as if I was playing it on 1024 x 768 with all high. I've also tried using Driver Cleaner and installing the 93.71 drivers.
My specs are:
AMD Athlone 64 3000+
2GB Ram
512MB 7600GS AGP
160GB HDD
Any ides as to what I can do?
