Unreal Tournament 2004
Just like in Half-Life 2, we see that high-end graphics cards easily reach their performance top in all resolutions. Nevertheless, in this one of the most popular games we can hardly see any performance improvement from the use of CrossFire technology in 1600x1200 with enabled antialiasing.
There is absolutely no performance increase in the Metallurgy level. Moreover, CrossFire system performs even slower than a single card would do. We notice some improvement in 1280x1024 in eye candy mode only. For a better comparison I would like to draw your attention to the fact that NVIDIA SLI works perfectly well here and demonstrates almost 70% performance improvement compared with a single-card mode.
