all graphics card support Direct X, or at least they should.
DirectX 9.0c will help improve multimedia experiences on most PCs. This latest version of DirectX offers improved security, updated graphics, faster frame rates, and support for massively multiplayer games. It also features more immersive audio when running and displaying programs rich in multimedia elements such as full-color graphics, video, 3-D animation and surround sound. If you had an earlier version of DirectX installed on your system, you will see little difference in available space on your hard drive following the installation. DirectX 9.0c will overwrite any earlier versions. This release also resolves an issue with DirectX 9.0 where some multiplayer games or MSN Messenger may not work correctly. A number of minor bugs were also fixed.
