AMD today released the Catalyst 8.3 drivers for ATI graphics cards. This edition packs a bunch of updates and new features like CrossFire X support and Hybrid CrossFire.
Advancing Multi-GPU Gaming with CrossFireX
Through three- and four-GPU configurations in CrossFireX, gamers can see
multi-GPU performance scaling across a range of today’s
most popular DirectX 9 and DirectX 10 games on Windows Vista -- up to 3.2 times
the performance over a single GPU in some scenarios.
The flexible architecture of CrossFireX allows for the mixing and matching of
high-performing ATI Radeon GPUs. Any ATI Radeon HD 3850, ATI Radeon HD 3870
or ATI Radeon HD 3870 X2 cards can be combined to harness the power of up to
four GPUs. CrossFireX also supports a wide range of platforms, enabling many
gamers to take advantage of three- and four-GPU gaming on their existing
Boosting Game Performance through ATI Hybrid CrossFire
ATI Catalyst 8.3 also introduces ATI Hybrid Graphics support for Windows
Vista. An industry first that is unique to AMD processor-based platforms, ATI
Hybrid CrossFire delivers a significant 3D performance boost. Up to 70 percent
increases in performance are possible in some gaming scenarios based on PCs comprised of an AMD 780G motherboard and ATI Radeon HD 3400 Series
graphics product in Windows Vista. ATI Hybrid Graphics also support up to four
independent displays through the SurroudView feature for those who want to
Additional Innovations Found in ATI Catalyst 8.3
Beyond multi-GPU configurations in CrossFireX, ATI Catalyst 8.3 introduces a
number of new features including:
- DirectX 10.1 and Tessellation Support:
ATI Catalyst 8.3 marks the first time DirectX 10.1 support for the ATI
Radeon HD 3000 series, and tessellation support for the ATI Radeon HD 3800
series have been made available to developers.
- Anti-Aliasing enhancements: ATI
Catalyst introduces anti-aliasing support for all Unreal Engine 3.0-based
games running in DirectX 9 mode. ATI Catalyst also allows users to enable
the Custom Filter Anti-Aliasing filters (box and wide tent) while running in
CrossFire Super Anti-Aliasing modes, providing superior image quality.

- HydraVision support for Windows Vista:
HydraVision support is now included in ATI Catalyst Control Center for
Windows Vista. HydraVision enables users to efficiently organize multiple
applications across single or multiple displays. You may configure up to
nine virtual desktops, and divide the Windows Vista desktop into definable
areas helping to easily move and organize multiple applications.
- Digital Panel GPU image scaling: For
those using widescreen displays, ATI Catalyst now allows users to enable
GPU-accelerated scaling to maintain the aspect ratio of the display while
providing superior image quality.
- Advanced Video Quality controls:
With ATI Catalyst 8.3, multimedia enthusiasts get further control over video
quality. Using the new edge enhancement feature, the level of sharpness of
video content can be adjusted. Through the new noise reduction feature,
ghosting artifacts can be removed while preserving the details of the
original video. The new slider controls can be found in the All Settings
page of the Avivo Video tab found in ATI Catalyst Control Center.
