GLSetup
What is GLSetup?
GLSetup is a program that detects your 3D graphics card and installs the
matching OpenGL drivers. GLSetup is included with Quake III Arena to
ensure your system has drivers available to accelerate OpenGL 3D rendering.
You will be asked during the install process if you would like to use GLSetup to install the lastest OpenGL drivers for your video card.
