DirectX contains a number of programs that handle multimedia for things like video games. Newer versions allow for more efficient processing and can greatly increase graphics quality and frame-rates. DirectX is embedded into the video card and cannot be updated without the purchase of a new video card. The latest version is DirectX 11 and is used by the Radeon HD 5000, 6000 and 7000 series and by the Geforce 400, 500 and 600 series.
