ATI Technologies Inc., today announced broad Catalyst™ graphics driver support for the beta 1 release of the Microsoft Windows Vista™ operating system. With its latest Catalyst driver releases, ATI is one of the first graphics providers to make a 64-bit driver that supports the Longhorn Driver Display Model (LDDM)—the Microsoft Vista revolutionary graphics driver standard—as well as the first to provide LDDM drivers for integrated graphics processors. Microsoft Windows Vista will make extensive use of 3D graphics for the desktop. ATI’s support of beta 1 enables the developer community to write a new class of visually stunning applications for the new operating system. By making LDDM drivers available more than a full year prior to Windows Vista release, ATI provides developers with a stable, feature-enabled and performance-optimized platform for application development. Included with Microsoft’s Windows Vista beta 1 release are ATI’s Catalyst drivers for its desktop and mobile DirectX 9 class discrete graphics processors as well as support for the 64-bit version of Microsoft Windows Vista. Additionally, ATI also is making available today on its website a further Catalyst LDDM driver which includes all of the functionality mentioned above plus support for integrated graphics processors in Windows Vista. A long-time supporter of Microsoft’s DirectX 9 application programming interface, ATI is working closely with Microsoft to ensure ATI graphics processors offer the best feature support and greatest compatibility with Microsoft Windows Vista. ATI’s complete line of DirectX 9 Radeon discrete graphics for desktop computers, Mobility Radeon graphics for notebook PCs and Radeon Xpress 200 chipsets with integrated graphics for motherboards offer fully featured driver support for the beta 1 release. ATI’s latest beta 1 driver release for Microsoft Windows Vista is available for download at www.ati.com.
