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 3D Prophet II Ultra tromps the non-Ultra cards, and matches the other Ultras tit for tat. At lower resolutions, the scores are more or less the same between all GeForce2 cards since the CPU limits performance. If you like to play at 1600x1200, the 3D Prophet II Ultra aims to please.
