CrossFire™ Overview 103
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.

SuperTiling has the advantage of being able to work with practically any 3D application. However, there are a small number of applications where the SuperTiling workload distribution does not provide optimal performance. For these special cases, Scissor Mode can be used.
