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.
