Unreal Tournament Performance

From our GeForce 2 GTS review

While Unreal Tournament does offer native support for Glide, we refrained from testing the Voodoo5 in Glide. Why? Have a look at the performance numbers taken from a Voodoo5 running Unreal Tournament in Glide vs Direct3D:

The first thing to notice is that there is no performance difference between 16 and 32-bit color when running in Glide, this is most likely due to Unreal Torunament not allowing 32-bit color/textures when running in Glide, especially since the scores were perfectly identical between 16 and 32-bit color modes.

Secondly, as the resolution increases, the performance of the Voodoo5 running in Glide mode drops below that of Direct3D indicating that it wasn't meant to be run at such high resolutions, which is one possible explanation.

Regardless, the Unreal Torunament scores were already difficult to explain because of the number of limitations acting on the Unreal Torunament engine (look back at our reasons that Unreal Torunament isn't a good benchmark) and adding Glide scores wouldn't do much good other than adding two more lines to the graphs.
