I did have to bypass the administrative account in Win 7 and use windows command prompt to get this to work but ATI WinFlash worked real slick. The shaders unlocked and I got the bump up in speeds of a default 6970. I cranked up all the sliders in Grand Theft Auto IV and used 1920 x 1080 and got 40 FPS from the in game benchmark. The game never slows down that I have noticed and the detail is superb. The core temperature is 80 degrees.
