Overall Analysis: Quake III Arena, Pentium III
Quake III will be happy as soon as you install the AGP driver (INF Utility) and a fast graphics driver. Neither the storage driver nor DirectX8 make any difference, as Quake III is based on OpenGL.
Overall Analysis: Quake III Arena, Athlon
Fans of Quake Arena should not forget to install their AGP driver with AMD760 systems. If you forget this one, it will clearly cost you on performance!
