Quake III Arena tests OpenGL performance through the scientific use of a rail gun and gibbed body bits. It uses advanced features such as curved surfaces and high-polygon models to bring your video card to its knees.
Normal mode uses 16-bit color, small textures, and relatively low complexity scenes.
In normal mode, the Voodoo4 stays strong up to 1024x768, then really starts to fall off. The GeForce2 MX stays well ahead of it.
