Ovladače grafických karet ATI Catalyst 9.3 přinášejí několik podstatných změn. Jedná se o poslední verzi, která bude pravidelně podporovat i starší karty než série HD 2000.
Nově jsou sjednoceny v jednom balíku ovladače pro systémy Windows Vista a Windows 7. Při instalaci bude systém detekován a podle toho nainstalována verze WDDM 1.0 (Vista) nebo WDDM 1.1 (Seven). Vista ovladače dostanou tradičně každý měsíc WHQL certifikaci, u nejnovějšího systému Microsoftu si budeme muset počkat až po jeho finálním vydání. Důležitější ovšem je slibovaný vyšší výkon Catalyst 9.3 ve Windows 7. Přesvědčit se o tom můžete v dnešním testu na ExtremeTech. O výkonu nových ovladačů píše i německý ComputerBase.
Zlepšení výkonu se dočkal klient Folding@Home běžící na ATI Stream technologii karet HD 2000 a novějších. Do balíku Catalyst byl přidán i ovladač HDMI audia. Viditelné zvýšení výkonu je ve hře Lost Planer: Colonies, očekává se až 20% nárust na kartách HD 4800 a až 50% na HD 4600, HD 4500 a HD 4300.
