Microsoft Reissues DirectX 9 Update
UPDATED Microsoft has released DirectX 9.0a for a second time, after it pulled the update due to a problem with ATI graphics cards. Most notably corrected in version 9.0a is an issue that caused MSN Messenger to malfunction when DirectX 9 was installed.
The initial DirectX 9.0a release was incompatible with ATI Catalyst 03.1 drivers, still in use by many gamers, according to Microsoft.
DirectX 9.0 made its debut last December featuring improved performance and security, along with a new high-level shader language designed to simplify development. However, graphics chipsets and games have only recently begun to take advantage of the DirectX 9 APIs.
Microsoft has updated the DirectX Web site with news of the release, and version 9.0a is available for download via Web installer. Microsoft notes the release also corrects problems with some multiplayer games and resolves other minor bugs.
