Hello. Sorry for my bad english...I'm Italian! I have a Radeon HD 2600 XT (AGP version) and I have installed Windows 7 build 7100 RC x64. Windows has installed its driver automatically without ask me what driver I want to use. The video card is recognized as Radeon HD 2600 XT AGP but the 3d performances are not so good. Now I want to uninstall the Microsoft driver (Microsoft corporation WDDM 1.1) and install the Catalyst 9.5 suite. How can I replace the Microsoft driver with the Catalyst one? Thanks!
