At 640 x 480 x 32 there are two main video card related factors that are altering performance. Those factors are drivers and the presence of hardware T&L. Hardware T&L gives the two NVIDIA cards and the Radeon a noticeable lead over 3dfx, while a combination of solid drivers and a strong T&L engine gives NVIDIA the slight lead over ATI.

Note that at this low of a resolution, the extra power and memory bandwidth of the GeForce2 Ultra based GLADIAC ULTRA give it no tangible advantage over the regular GeForce2 GTS.

At 1024 x 768 x 32 the GLADIAC ULTRA begins to pull away from the GeForce2 GTS which is already distancing itself from the Radeon and the Voodoo5. Note that the move from 640 x 480 x 32 to 1024 x 768 x 32 results in a drop of no more than 7% while the same resolution change impacts the GeForce2 GTS by almost 20%.

The Radeon takes a performance hit similar to the GeForce2 GTS when going from 640 x 480 x 32 to 1024 x 768 x 32 while the Voodoo5 5500 feels a slightly lesser 15% drop in performance.

At 1600 x 1200 x 32 the GLADIAC ULTRA begins to shine as it is just 2 frames shy of the magical 60 fps mark. At this point the line is blurred between the performance of the GeForce2 GTS and the Radeon 64DDR, while the Voodoo5 holds up the rear. There's no question about the fact that the GLADIAC ULTRA, courtesy of NVIDIA's GeForce2 Ultra design, is currently the fastest available gaming solution.
