ATI Technologies X1950 PRO - Manual (Page 20)

14 CrossFire ™ Rendering Modes
The first three are performance-oriented modes, while Super Anti-aliasing is
a quality-oriented mode. Each mode uses a different method for dividing the
workload required to render a 3D image across multiple GPUs. Only one
mode can be in operation at any given time.
The ATI Catalyst
™
display driver will automatically select the best of the
three performance modes when a 3D application is started, without requiring
user intervention. The user can also choose to improve image quality by
selecting the new Super Anti-aliasing modes in the Catalyst
™
Control Center.
