I experiment the same problem: it seems that Cod is not detected by the driver as a 3D videogame with some video cards; so the frequency of GPU and memory remains stuck to minimum (in my case GPU 100 Mhz and memory 150 Mhz) and does not reach the max frequency (in my case GPU 775 Mhz and memory 1000 Mhz).
If I use a third part tool like Ati Tray tool that can locks the frequency to the maximum, I can play the game with "High" settings, otherwise "medium" settings are too much for me.
My card is the ATI 6850, driver Catalist 11.3, Win7 Ultimate 64 bit.
