I have a new 15" Macbook Pro with a 6750m. I installed bootcamp and Windows 7 Professional. For the last few weeks I have been gaming on it with no problems and great framerates. Today I boot up Win7 and my games are sluggish. Turn on fraps and the FPS's are really low. After checking GPU-Z I have found out that the GPU is not up-clocking to 600Mhz core and 794Mhz memory, but staying at 100 and 150Mhz, respectively. I reinstalled the Catalyst drivers, but it still reports 11.2 and not the new 11.3. Anyone have some ideas I can try? I've got none left.
