3Dlabs Oxygen GVX210 User's Guide

Direct3D Support Screen

The Direct3D Support screen controls Direct3D application specific driver settings for Oxygen GVX210

Windows 98 and Windows 2000 users, and lets you create your own settings. When the panel first appears,

the

Defaults

Add New

and

Remove Settings

buttons, as well as the

Advanced Options

section, are hidden. They

appear when you click the

Advanced

button.

Click

Driver is optimized for application

to reach a drop down list of Direct3D applications, then

select the application you want to use. The rest of your selections on this screen will apply to the

specified application. You can also click

Select optimized application

in the Configuration Manager

and select your application from that pop-up list.

The

Add New

button lets you create a new setting, with a user specified name.

Remove Setting

will

remove user created settings, but will not remove the default settings created at driver installation

time.

Default

will restore the factory default settings.

Texture Origin at Top Left Corner

shifts textures slightly as they are applied to objects, and may result

in better image quality with some applications.

8Bit RGB textures

enables Direct3D support for 8bit textures that do not use a separate “look-up”

table to specify color. These can be useful for applications that 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.

Disable 16-bit alpha-luminance

textures enables Direct3D support for monochrome (luminance)

textures. These can be useful for applications that 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.
