• Disable 16-bit alpha-luminance textures enables Direct3D support for monochrome
(luminance) textures. These can be useful for applications which use the new features
of DirectX 6, but older applications can misinterpret these new formats. If you have
problems such as incorrect colors or poor quality texturing, try disabling this option.
• Enable Palettized textures enables Direct3D support for 8bit textures which use a
separate “look-up” table to specify the color.
These are useful for graphics cards with
a small amount of memory. However, they can be slower than the alternatives
available on cards with large amounts of memory. For best performance this option
should only be enabled for applications that will not operate correctly otherwise.
• Disable Direct3D Gamma Controls lets you turn off DirectX gamma control if you
experience an extremely dark screen, potentially caused by an application’s use of an
incorrect default.
• Gamma adjustment for this application affects the entire screen display. As with the
contrast on your television, you can adjust this value if your application causes the
display to consistently look too dark or too light.
