Drivers provided by Windows can only offer basic device performance. To get optimal performance, you must install the latest version drivers provided by their hardware manufacturer. The most important thing to notice is that the drivers provided by Windows do not contain a control panel for hardware configuration. For example, if you don't install the latest version drivers provided by the manufacturer for video cards, you can't configure the OpenGL and Direct3D options for the video card. This can obviously lower video quality and FPS of 3D images in games. The same thing will happened on sound card, Windows drivers can't offer EAX sound effects, 3D sound effects, or Dolby multi-channel surround stereo. So install a suitable driver will enhance the full performance of system.
