ATI releases Catalyst 6.4 drivers

— 6:59 PM on April 12, 2006

ATI has released new Catalyst 6.4 drivers for its desktop Radeon graphics cards. The drivers improve standard definition image quality with ATI's Avivo video processing engine, and introduce a new video conversion utility for Windows Media Center Edition. The utility can convert video to MPEG-2, MPEG-4 SP, MPEG-4 AVC, and Windows Media formats. A number of performance increases are also on the menu for Radeon X1900-series graphics cards, with ATI claiming Half-Life 2 and Far Cry frame rates boosts of 3% and 3.8%, respectively. Call of Duty 2 apparently sees a 1.4-2% improvement with X1900- and X1800-series CrossFire setups, and Unreal Tournament 2004 performance is supposedly up by 3-5% on all X1000-series cards. Aside from the performance gains, the drivers also enable CrossFire AFR mode in The Elder Scrolls 4: Oblivion, and fix a number of issues with Doom 3, Quake 4, Serious Sam SE, and several other applications. A complete list of fixes and enhancements is available in the driver release notes, which can be downloaded here.

The release notes don't tell the whole story, though. A quick peek inside the drivers' INF file shows an entry for an unannounced Radeon X1900 GT graphics card, giving further credence to a number of rumors that have been circulating this week.
