By now you’re probably wondering how the Preview Driver stacks up against our most recent release, AMD Catalyst™ 11.2. We raised our baseline image quality in 11.2, so the performance improvements going to the 11.4 Preview should be pretty small, right? Wrong. Based on various configurations, resolutions and settings, our internal data still shows pretty amazing improvements!

* Up to 23% performance improvement in Aliens vs. Predator
* Up to 22% performance improvement in Batman: Arkham Asylum
* Up to 15% performance improvement in Battleforge
* Up to 72% performance improvement in Civilization V
* Up to 59% performance improvement in Call of Duty: Black Ops
* Up to 26% performance improvement in FarCry 2
* Up to 35% performance improvement in Lost Planet 2
* Up to 30% performance improvement in Metro 2033
* Up to 11% performance improvement in S.T.A.L.K.E.R.: Call of Pripyat
* Up to 19% performance improvement in Chronicles of Riddick: Assault on Dark Athena

And one more thing: the AMD Catalyst™ 11.4 Preview Driver (and its official release in April) is only the first in a series of planned drivers that we hope will provide even more performance throughout 2011.

NOTE: This preview driver is only available for Windows® 7.
