Unreal Tournament 3
We are promised an 18% performance growth in Unreal Tournament 3 with Catalyst 8.12 when full-screen antialiasing is enabled. And the frame rate is indeed higher, even though not as much higher as promised: about 6% at 1280x1024 and 11% at 1920x1200 relative to the Catalyst 8.11 results. That’s good.
Devil May Cry 4
This test indicates that ATI had been unprepared for the Radeon HD 4870 release in terms of software support. The much lower performance of the card with the first official Catalyst is due to the absolute lack of useful optimizations in the driver. I say useful because I did not spot any difference in image quality between Catalyst 8.10-8.12 and Catalyst 8.7 in any of the four tests of the game’s built-in benchmark.
S.T.A.L.K.E.R.: Clear Sky
You see a small but almost linear growth of the card’s performance upon installing a newer version of Catalyst at a resolution of 1280x1024. The developer promised a 10% performance gain with Catalyst 8.12 for CrossFire configurations only, though.
