|"Whenever I open a game or application that uses graphics (examples include Homeworld 2, Empire at War, Football Manager (which is 2d graphics), or even ATITool (which just features a spinning cube) ) the CPU maxes out to 100%"|
I own an Radeon 9500 mod 9700 360/585, when I open ati tool to show the 3D view, it also use 100% CPU, there is nothing wrong with that. As long as the programs you open yourself ultilize 100%, I see nothing wrong with that. For example, I open homeworld2.exe and it uses 100%, it is normal... What is not normal is when yo open homeworld2.exe, it uses 10% and some other background program like xxxx.exe uses 90% or without open any program, the CPU ultization is 100%, then either you have sypware or virus on your computer... What I would do is whatever you install a new graph card, always uninstall your old drivers before installing new ones. Go to www.ati.com to download the latest driver for your r9600...
