Your only solution is to artificially set the clock speed via a tool like Riva Tuner to double the defaults. When you run across one of these cards you will notice immediately, as the 5600 even with 64mb of RAM on a 1280x800 display will draw pretty slowly with Aero on. (And NO THIS HAS NOTHING TO DO WITH POWERMIZER or the Video Card running in 2D or 3D performance Clock speeds.) Some of the 64mb cards and PCI cards, you can use Aero, but just turn off the 'transparency', this will let you keep the features of the DWM, and not have any slow down.Īlso to note, there are a few 5200s and 5600s that I have personally ran across that for whatever reason clock to 1/2 the speed, so the GPU and GPU RAM will report it is running at the normal speed, but in fact is running at 50% the speed it is, and there is not any easy way to tell, as even tools like Rivatuner report what the card says and it thinks it is running at 100% of the GPU speed. Couple Tips for the 5xxx Geforce cards on Vista and Win7, and a request.
