ATI vs NVIDIA: Driver performance under Win98 & Win2K

Epic Games' UnrealTournament

UnrealTournament is also another benchmark that we are quite familiar with as it is a standard part of our benchmark suite here at AnandTech. 

This Direct3D test was conducted with all settings left at their defaults with the obvious exception of the resolution and color depth. We used Reverend's Thunder Demo for the test.

Since Rune was based on the UnrealTournament engine and both cards took a performance hit under that benchmark, we expected a similar showing here.  And although we did technically get similar results as in a performance drop among both candidates, the percentages were obviously much different.

The Radeon dropped a total of 46%, tying the performance drop that was noticed under Expendable. 

NVIDIA's performance drop was restricted to, at most, 3% unlike the 12% drop under Rune.
