DirectX is a collection of application programming interfaces (API) for handling tasks, especially those related to game programming and videos. Basically, it is a program which helps boost the graphics for games developed with API. It also provides good audio quality, full-color graphics, video, 3D animation, and surround sound. The process involves DirectX acting as an interface and then sending instructions to the game video cards.
DirectX 9.0 was the parent of today’s more popular versions 10 and 11, which are more flexible and efficient. Updates for these later versions include security and performance updates, as well as support for massively multi-player games.
Among the key features of DirectX 9.0 are the following:
• Support for Pixel Shader and Vertex Shader 3.0
• Multi-threading: where developers can take full potential of multi-core CPUs, resulting in faster frame rates for games as well as increase in visual detailing
• Direct Compute: where developers can utilize the power of discrete graphics cards to boost gaming and even non-gaming applications. This therefore leads to an improved graphic quality without compromising the performance of everyday computer applications such as Internet use.
A DirectX compliant video card needs to be installed first in order to maximize the features of the DirectX applications.
