102  CrossFire

™

 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.
