• An interconnect cable, supplied with the CrossFire™ Edition
Series graphics card, connecting the two cards to a single monitor,
if required (See the CrossFire™ Edition Series' Getting Started
Guide for more information.)
When CrossFire™ is enabled, any one of the four following display modes
are available:
• SuperTiling - A graphical load-balancing scheme where
CrossFire™ renders alternate small 32x32 pixel squares in a fine-
grained checkerboard pattern. This configuration increases image
rendering quality, as each card processes half of the complex 3D
objects in the pixel squares.
• Scissor Mode - A graphical load-balancing scheme where two
graphical cards are used to render two halves of an image display.
One graphics card renders the top half of the screen while the
second graphics card renders the bottom half.
• Alternate Frame Rendering - A graphical load-balancing scheme
where two graphics cards are used to render alternate frames of the
display. This configuration increases the detail of the 3D objects
each card can render, as each card handles half of the total number
of frames.
• Super Anti-aliasing - A feature that improves image quality by
combining the results of full-screen anti-aliasing across two
graphics cards in a CrossFire™ configuration. The two graphics
cards work on different anti-aliasing patterns within each frame.
It is recommended that Catalyst™ A.I. is enabled because it selects the
preferred rendering mode for target applications. For applications that are
not identified in Catalyst™ A.I., or when Catalyst™ A.I. is disabled,
default CrossFire™ rendering modes are used.
By default, either SuperTiling or Scissor modes are applied, depending on
the application. Alternate frame rendering mode is used for applications
identified in Catalyst™ A.I. when enabled. Super Anti-aliasing is enabled
through the Catalyst™ Control Center.
