DirectX 9. 0c will help improve multimedia experience on most PCs. This latest version of DirectX offers better security, updated images, faster frame rates, and support for massively multi-player games. It also features more immersive audio tracks when running and displaying programs rich in multimedia elements such as full-color design, video, 3-D animation and audio. If you experienced an earlier version of DirectX installed on your whole body, you will see little difference in available space on your hard drive following the installation. DirectX 9. 0c will overwrite any earlier versions. This kind of release also resolves a number of minor pests and includes security improvements.
