36 CrossFire™ Rendering Modes 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. SuperTiling In this mode, each frame to be rendered is divided into a number of tiles in an alternating checkerboard pattern, so that half of the tiles are assigned to each of the two GPUs. Each tile is kept to a relatively small 32x32 pixel square, so this method does a good job of balancing the workload across each GPU regardless of what is being rendered on the display, doing so without any software overhead. 1 PCI Express® CrossFire™ Compatible Graphics Card 2 Radeon® X1950 XTX CrossFire™ Edition Graphics Card
