GLSetup detects your 3D graphics card and installs the matching OpenGL drivers. Games supporting OpenGL will include GLSetup to ensure your system has drivers available to accelerate OpenGL 3D rendering.
GLSetup is web-enabled. You download a small executable to your system and run it, and it will detect your 3D hardware and continue downloading the correct drivers over the internet. This alleviates the need for you to download the entire GLSetup driver package just to get a single driver.
