For the gamers out there, this is the big one for you - CATALYST 5.6 sees an extension to the number of titles which make use of ATI's CATALYST A.I feature to leverage specific optimisations for certain titles, and thus boost performance in these games. Here's the list of what benefits from these additions, and the changes which have been applied.

- Doom 3 benefits from more efficient memory usage
- Chronicles of Riddick utilises the more efficient storage of vertex data
- Call of Duty makes use of optimisations previously limited to Doom 3 to increase its rendering efficiency
- Lock On: Modern Air Combat force enabled texture compression within the game without sacrificing image quality, making for massive performance gains

Away from CATALYST A.I., ATI have also implemented some Z-optimisations - These affect all titles across the board, but the benefit from these changes can be seen most specifically in the likes of Halo, AquaMark 3, 3DMark 05 and Tomb Raider: Angel of Darkness.

ATALYST 5.7 is slated to be the first WHQL driver release to support ATI's multi-GPU technology, CrossFire. This means that the CATALYST A.I. feature will be expanded upon to choose the appropriate rendering mode for game titles, and extra anti-aliasing options will be available to CrossFire users allowing them to select 8x, 10x, 12x and 14x 'SuperAA' modes.
