Overview
CrossFire
™
Rendering Modes
A CrossFire
™
system has four possible display modes:
• SuperTiling
• Scissor Mode
• Alternate Frame Rendering
• Super Anti-aliasing.
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.
