Diamond Multimedia 7500 User Manual

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. 

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 DXT 
texture formats, thus reducing the number of texture 
formats supported.

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.

This button allows you to reset the Direct 3D 
Compatibility Settings to default values.
