As expected, AMD has rolled out its latest monthly Catalyst release, the Catalyst 11.7 WHQL. The new driver supports all the card from Radeon HD 2000 days and although it doesn't bring any new features or impressive performance gains it does fix a rather large amount of bugs found in previous versions of Catalyst. In addition to the new 11.7 WHQL version, AMD has also rolled out the new preview driver as well, dubbed Catalyst 11.8 Preview.
As noted, the Catalyst 11.7 WHQL brings a rather large list of fixes including mouse cursor lag, some problems with 11.6 driver and HDMI/DP displays, 720p DivX problems on Windows Media Center and Windows Media Player, some problems with various games in both single and Crossfire configurations, problems with various applications including PowerDVD, VLC Player, WinDVD 10 and much more.
On the other hand, the 11.8 Preview driver, available only for Windows 7 64-bit brings a couple of rather interesting features and pefromance updates. The most important one is the HD3D technology support for 3D monitors via DisplayPort. The list of perfromance updates includes Crysis 2 by up to 10 percent on Radeon HD 5000 and 6000 series cards as well as up to eight percent in Fear 3 under DirectX 11 with the same series cards.
The last is a performance improvement of up to 30 percent when AMD's Morphological Anti-Aliasing (MLAA) is enabled via Catalyst Control Center on Radeon HD 6000 and HD 5000 series cards.
