New Features

This release of Catalyst® introduces the following new features:

Overlay Theater Mode Update

Catalyst® 6.5 introduces a new option for Overlay Theater Mode. The new option, Standard Dual Mode is available for Radeon® X1x00 series of graphics cards. This new feature now allows users to playback video using hardware acceleration when it is played on both displays (clone mode). Hardware acceleration decreases CPU utilization, allowing the PC to run smoother and faster. When using two displays in clone mode, video playback will be identically displayed on both display devices. For Radeon® X1000 series products (Avivo Video) overlay is per-display and true overlay will be used for both displays. For pre-Radeon® X1x00 boards, there is only one hardware overlay, so video on the second clone display device is either software-rendered (i.e. "Same on all" selection) or the Windows desktop is displayed but the video will not show through the color key (i.e., "Standard mode" selection).

Adaptive Anti-Aliasing for ATI Radeon® 9500 and above

Adaptive Anti-Aliasing smoothes out the surfaces in an entire scene unlike Multi-Sample which works only on edge surfaces. Adaptive AA has the ability to work on transparent or opaque texels, like those that comprise a surface texture. Previously this feature was available on the ATI Radeon® X1000 family products. Starting with Catalyst® 6.5, Adaptive AA support is now available to ATI Radeon® 9500 products and above.

Performance Improvements

As with most Catalyst® releases, performance has increased in various situations. The PCI Express bandwidth optimization code in Catalyst® 6.5 brings performance improvements for both the ATI Radeon® X1600 and Radeon® X1300 Crossfire configurations, including:
