AMD Catalyst 11.4 WHQL Released

The April 2011 edition of AMD Catalyst drivers is available with the following new features:

• Enhancements to the AMD VISION Engine Control Center / AMD Catalyst Control Center.
  • New task based Display Management controls. Simplifies the configuration of displays and display settings
  • New Eyefinity setup group. Setting up an Eyefinity group has never been easier
  • AMD Catalyst update notification (found within the Information Center). This feature notifies users that new AMD Catalyst software packages are available
• GPU Compute enhancements: the OpenCL runtime (included in AMD Catalyst 11.4) includes performance enhancements supporting zero-copy on APUs and increased performance for PCIe transfers between a CPU and discrete GPU.

More information in the release notes.

The new OpenCL runtime was already available with AMD APP SDK 2.4.
