Compatibility Settings
This will enable W-Buffer support for 3D games. It is
recommended to disable this for games that do not
support this feature. Certain applications require the
increased precision of W-Buffering and will exhibit
artifacts unless the W-Buffer is enabled.
Z-Buffer Bit Depth can be 16 bits, 24 bits, or 32 bits. 16
and 24 are selected by default to achieve optimum
performance. Very few applications require a 32 bit Z-
Buffer, so in most cases this feature should be disabled.
When applications use both dithering and alpha
blending, visual artifacts can occur. This option allows
you to select how the application should handle both
features at the same time. In most cases Error
Diffusion will handle this situation quite well, but there
are a few cases where selecting Ordered may be
necessary.
