DirectX

programming, hardware A Microsoft programming interface

standard, first included with Windows 95. DirectX gives

(games) programmers a standard way to gain direct access to

enhanced hardware features under Windows 95 instead of going

via the Windows 95 GDI. Some DirectX code runs faster than

the equivalent under MS DOS.

DirectX promises performance improvements for graphics, sound,

video, 3D, and network capabilites of games, but only where

both hardware and software support DirectX.

DirectX 2 introduced the Direct3D interface. Version 5 was

current at 1998-02-01. Version 8.1 is included in WindowsXP.

Current version: 8.1 (as of 2001-12-31).
