MDK2 is, like Quake 3 Arena, an OpenGL game that by the way doesn't benefit from Pentium 4 as much as Quake 3 Arena.
The scores are similar to the Q3A-scores. Even with quincunx-FSAA enabled, GeForce3 is still scoring extremely respectable.
We already know the picture. At 1024x768x32 GeForce3 is able to leave the rest behind, while it can even compete with Radeon DDR 64 MB if quincunx-FSAA is enabled.
There's no doubt that GeForce3 is a 3D-chip that finally makes 1600x1200x32 reality, although not quite with quincunx-FSAA enabled.
