Nuovi Driver ATI Catalyst 8.6!

AMD ha reso disponibili per il download una nuova versione di driver Catalyst, sia per sistemi operativi Windows XP e Vista che per quelli Linux. Tra le principali novità segnaliamo varie ottimizzazioni prestazionali con alcuni titoli, in particolare per le schede video ATI Radeon HD delle serie 2000 e 3000, oltre all'inclusione del supporto all'Adaptive Anti Aliasing con API Open GL.
Il supporto alle tecnologie CrossfireX con 3 e 4 schede video in parallelo è stato inoltre esteso anche alle API Open GL: con le precedenti versioni di driver questo era infatti limitato alle sole API DirectX.



Queste le principali novità implementate nei nuovi driver Catalyst per sistemi operativi Windows XP e Windows Vista:
