5How are the graphics cards connected on a CrossFire™ system?

Two Radeon® X1950 Pro cards are connected by two CrossFire™ Bridge Interconnects, connecting the custom DVO ports on each card together. To see where the DVO ports are located on the Radeon® X1950 Pro cards, see the picture of the Radeon® X1950 Pro CrossFire™ implementation.

6Which games/applications work with CrossFire™?

CrossFire™ works with all 3D games and applications. If Catalyst™ A.I. is enabled in the Catalyst™ Control Center software, the optimal rendering mode available for the application is automatically selected.

7Is a driver profile required to make CrossFire™ work?

No. CrossFire™ is enabled by default for all 3D games and applications.

8What are the rendering modes, and what are their specific advantages?

The following dynamic rendering modes are available:

•SuperTiling - CrossFire™ renders alternate 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 - each graphics card renders up to half of the display, either vertically or horizontally depending on the game or application.
