28 CrossFire™ Rendering Modes
The ATI Catalyst
®
display driver automatically selects the best of the three
performance modes when a 3D application is started, without requiring
user intervention. You can also choose to improve image quality by
selecting the new Super Anti-aliasing mode 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.
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.
