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.

The new driver fixes some flicker issues in Crossfire with WOW and WOW: Wrath of the Lich King, Google Sketchup no longer displays blank screen, resolutions above 1,024x768 will have proper full screen for specific HDMI displays and artifacts in Age Of Conan DX10 are fixed.

The new driver also fixes CAL driver, Overlay Theater Mode corruption after enabling 3D screen saver and OS display setting for Component Video under Windows XP, as well as bunch of issues under Windows 7 which include fix for City of Villains which now redraws correctly after changing graphics settings. It also fixes some component video mode issues, custom format modes, issues with diplay profiles restore after system sleep, jitter and flicker issues in WinDVD9 HD playback, and errors in device manager after express driver uninstall.
