Alpha
dithering
method
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.
Support DTX
texture
formats
Enabling this allows applications to use this kind of
texture format. There are a few applications that can
only support a limited number of texture formats. By
selecting Disabled, the driver will not support DTX
texture formats, thus reducing the number of texture
formats supported.
Alternate pixel
center
This may eliminate problems with some D3D games
which display vertical and horizontal lines around
textures, or text that appears incorrect. However, this
setting should only be used if you are experiencing the
symptoms mentioned, as it may cause problems with
other games.
Defaults
button This button allows you to reset the Direct 3D
Compatibility Settings to default values.
