TV Out Support 3
SMOOTHVISION™ HD is an antialiasing solution that raises the bar for
image quality using programmable multi-sampling methods to post-
process graphics before they are displayed.
SMARTSHADER™ HD is a technology that allows specialized high
precision graphic programs to be run on the RADEON® X1900 G5 MAC
EDITION VPU rather than the system processor. Developers can easily
create amazing new graphics effects while maintaining a high level of
performance.
HYPER Z™ HD makes Z-buffer bandwidth usage more efficient by
decreasing the amount of information sent to the frame buffer at higher
resolutions than ever before.
RADEON® X1900 G5 MAC EDITION only displays 3D graphics in
thousands and millions of colors. When you set your display to 256 colors,
this will affect Finder™, OpenGL®, Quartz® Extreme, and QuickTime®
