Typically ATI does not release NON WHQL certified drivers, but as it seems ATI will release a beta today which we'll post once available. The driver should help out with a LOT of performance improvements for several game titles. The non-WHQL driver features a couple of enhancements that weren't ready in time for the WHQL driver, this includes Eyefinity 6 (which we'll actually review soon with six monitors) updates and a performance enhancement for Alien vs. Predator. Here's an overview of the new features in Catalyst 10.3:
ATI Eyefinity Technology Bezel Correction - compensate for your bezels so objects in your game move from one display to the other smoothly ATI Catalyst Mobility - monthly updates for the mobile crowd ATI Eyefinity Technology Per Display Control - adjust for differences in each individual displays brightness, color and contrast ATI Eyefinity Technology Multiple Display Groups - more display groups to give further control of your desktop with three displays or more connected ATI Eyefinity Technology Display Configuration Switching - easily switch from one display mode to another 3D Stereoscopic 3D driver hooks - enables 3rd party middleware vendors to bring more 3D stereoscopic gaming optionsHere's a list of performance enhancements you can expect from Catalyst 10.3a:
