AMD today announced that its Windows 7 driver has received Windows Hardware Quality Lab (WHQL) certification on the first day of the certifying program.

For users of ATI Radeon HD 2000, HD 3000, and HD 4000 series products, the ATI Catalyst software suite delivers stability, full WDDM 1.1 WHQL certified support under Windows 7 and enablement of ATI Stream technology for general purpose GPU (GPGPU) computing on supported graphics cards.

Microsoft WHQL certified graphics drivers for Windows 7 are scheduled for release on AMD.com on May 5, 2009, and a fully unified WHQL-certified driver supporting Windows Vista and Windows 7 is planned for the release of ATI Catalyst 9.5 later in May.
