Fudzilla: "As promised, AMD has released its new Catalyst driver, version 9.4. The new driver supports all the cards in the ATI Radeon HD 2000, 3000 and 4000 series, as well as ATI's 3000 IGP series. Beside some minor fixes in Windows Vista, XP and 7, the new driver comes with a new ATI Overdrive auto-tune application designed for the Radeon HD 4000 series cards.
The new auto-tune application in Overdrive is part of the ATI Catalyst Control Center. As you probably already know, ATI Overdrive auto-tune application is used to determine the best overclocked GPU and memory values. The new auto-tune is designed for the Radeon HD 4000 series cards."
