DirectX is the multimedia system foundation for Windows operating systems. This latest version of DirectX (released very recently) offers updated graphics, faster frame rates, and support for massive multiplayer games. It also offers more immersive audio when running and displaying programs rich in multimedia elements, such as full-color graphics, video, 3D animation, and surround sound. The Windows2000 binary is 7.6 MB while for Windows98/98SE/ME, the download weighs 11.5 MB. Users of Windows XP do not need to install DirectX 8.1 as it is already included, while Windows95 is not supported at all anymore.
