Limits the surface formats exposed as Direct3D texture formats.  This may help prevent buffer overruns in older applications that expect a limited number of texture formats.  Default is to limit formats in Direct3D 5.0 and lower APIs.

The following options are available:

Disabled

Exposes all supported pixel formats as texture formats.

Enabled for DX5 and below

Exposes all supported pixel formats when using Direct3D 6.0 or above APIs; when Direct3D 5.0 or below APIs exposes a limited subset of supported pixel formats.

Enabled always

Always exposes a limited set of supported pixel formats to Direct3D APIs.  This setting is not recommended.
