Operating systems such as Windows 7 and Windows Vista feature support for Microsoft DirectX 10. High-end games that use the pixel shader 4.0 technology require DirectX 10 to be present in order to run successfully. However, the video card you use must also support DirectX 10. If your video card does not support DirectX 10, your computer will only run in DirectX 9 mode.
