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. V-sync was disabled in all tests.
Normal mode tests 16-bit performance.
In normal mode, the Voodoo5 PCI is the slowest card by far. The AGP version is a bit faster and the GeForce2 GTS card is far ahead.
