AMD has received Microsoft's nod of approval for the Catalyst 11.4 preview drivers released last month and the WHQL-certified version is awaiting your download below. Unlike March's official update, the latest build delivers a slew of new features and performance enhancements – especially for folks running the new Radeon HD 6800 or 6900 series graphics cards. Those products receive the following speed boosts:

  • Aliens vs. Predator - gains of up to 8% with Anti-Aliasing and Anisotropic Filtering on single and multiple GPU configurations.
  • Batman Arkham Asylum - gains of up to 20% with Anti-Aliasing and Anisotropic Filtering on single and multiple GPU configurations.
  • Battleforge - gains of up to 15% with Anti-Aliasing and Anisotropic Filtering on single and multiple GPU configurations.
  • Call of Duty Black Ops - gains of up to 15% with Anti-Aliasing and Anisotropic Filtering on single GPU configurations.
  • Civilization 5 - gains of up to 15% on single and multiple GPU configurations.
  • Far Cry 2 - gains of up to 6% on single and multiple GPU configurations.
  • Just Cause 2 - gains of up to 9% on single and multiple GPU configurations.
  • Lost Planet 2 - gains of up to 10% on single and multiple GPU configurations.

Catalyst 11.4 also brings several improvements to the Catalyst Control Center and AMD Vision Engine Control Center, including new task-based Display Management controls that simplify the configuration of displays and related settings, as well as a new feature to set up an Eyefinity group. AMD also added a notification feature that tips users off when a new driver package is released, just as Nvidia did with its latest update.
