It's only been two weeks since the last official Catalyst update, but AMD has slipped out a fresh driver suite and hotfix today. Considering the brief window since Catalyst 11.4's release, it should come as no surprise that version 11.5 doesn't contain anything too spectacular, but AMD has ironed out a few kinks alongside a couple of adjustments to Hydravision.
According to 11.5's release notes, the HydraGrid feature found in HydraVision is now aware of user-created bezels. HydraGrid now also includes an "Automatic Grid" option that aligns to the user-defined display layout. AMD also solved one bug in Windows XP and seven in Windows 7. The XP flaw appears to be limited to Civilization V, causing the game to crash upon launch when Crossfire is enabled.
The Windows 7 flaws included two that crashed PowerDVD, one that caused VC1 videos to hang in WMP, an issue with Avivo settings in the AMD Vision Engine Control Center, one that caused visual corruption in BioShock, and two transcoding bugs (MPEG-2 to H.264 and H.264 to AVCHD). As we said, there's not much going on in Catalyst 11.5, at least when it comes to performance optimizations.
Meanwhile, the Catalyst 11.5a hotfix offers speed enhancements for Splash Damage's Brink, which launches tomorrow. It also delivers another transcoding fix along with resolving an issue with mouse cursor lag. Another bug caused flickering problems with the Radeon HD 6600 series cards when playing various games in DirectX 9, including Civ V, Dead Rising 2, Fallout 3, Mafia 2, StarCraft 2 and WoW.
