Unreal Tournament is a heavy load on the CPU and offers a lot of effects. The game benefits from a high memory bandwidth of the graphics card and system memory, but does not use T&L. Although Unreal Tournament supports various interfaces such as OpenGL, S3TC, Glide and Direct3D, we only use Direct3D in 32 bit, with maximum quality. The Unreal Tournament benchmark is less CPU limited than the UTbench and therefore gives very good statements about the average performance. It shows a 4 against 4 capture the flag game with partly human players and partly bots.
The benchmark from UT delivered interesting results, while the GeForce3 did another has a good lead in 800x600, but loses it at a resolution of 1024x768 bit. The PowerMagic Radeon 8500, clocked at 275/275 MHz, even lost frames, which led to unreal, random results in the higher resolutions. The reason for this could be too aggressive memory timings, as UT demands a lot from the graphics card in this regard, the same problem was already known to us when overclocking the GeForce 2 Ultra.
We got another interesting result, which we didn't It is representative, but worth mentioning, namely with the UT.ini optimized for GeForce cards, i.e. the freely selectable settings allowed for the benchmark according to the references from 3DCenter were optimized for the performance of the GeForce 2/3, which is the case with The Radeon 8500 led to fatal performance drops.
In principle, the UT benchmark can therefore only be used to a limited extent to compare cards with one another - that is, only for cards with the same chipset.
