I have according to windows 8 an AMD Radeon HD 7500 series card. I downloaded the latest drivers which should include the Catalyst control panel and installed as noted. However, when I got to adjust the card, there is no catalyst control panel to adjust anything with. I was one time able to get the catalyst to show up, only telling me that Cataylst could not open as there are no settings to change on the card.
I am using Windows 8 64bit (X86 based)
It is on Dell XPS desktop
AMD HD Radeon 7500 series
