DirectX improves multimedia experiences on most PCs. This latest version of DirectX offers better 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 a number of minor bugs and includes security updates.
