ATI's OpenGL® Tab: 128MB DDR ATI Radeon™ 9700 TX with TV-Out User's Guide


OpenGL® Tab

Main and Custom Settings

In the Main Settings you can maximize overall performance by moving the slider to the left, or you can enhance overall image quality by moving the slider to the right.

When Custom Settings is checked, the Main Settings slider is disabled, allowing you to move each individual slider in the Custom Settings section below. Setting the individual sliders gives you complete control over your application experience. Using Custom Settings is recommended for advanced users only.

   
SMOOTHVISION II Anti-Aliasing Disabled checkbox Check this to disable Anti-aliasing. This setting overrides OpenGL® applications' anti-aliasing setting.
SMOOTHVISION II Anti-Aliasing Samples Box When the Anti-aliasing slider is enabled, indicates the number of samples taken per pixel.
SMOOTHVISION II Anti-Aliasing slider SMOOTHVISION/Anti-aliasing enhances 3D image quality by softening the jagged edges found in 3D scenes, providing smoother, more realistic 3D objects. Increasing the number of samples results in better image quality. Move the slider to the right to increase the number of samples taken per pixel.
SMOOTHVISION II Anisotropic Filtering Application Preference checkbox Check this to enable Application Preference. This gives OpenGL® applications the ability to enable Anisotropic Filtering. The application uses the Performance or the Quality mode, depending on which is selected. If an application does not specify, then anisotropic filtering is not enabled.
SMOOTHVISION II Anisotropic Filtering Samples Box When the Anisotropic Filtering slider is enabled, indicates the number of samples taken per pixel.
SMOOTHVISION II Anisotropic Filtering slider Anisotropic Filtering enhances 3D image quality by increasing the number of texture samples taken per pixel, resulting in highly detailed 3D scenes. Increasing the number of samples results in better image quality. Move the slider to the right to increase the number of samples taken per pixel.
SMOOTHVISION II Anisotropic Filtering Performance button Check this to enable Performance Anisotropic Filtering. This offers enhanced image quality while maintaining high OpenGL® performance levels.
SMOOTHVISION II Anisotropic Filtering Quality button Check this to enable Quality Anisotropic Filtering. This uses an advanced anisotropic filtering technique to provide the best possible image quality.
Texture Preference slider The Texture Preference slider enables you to select the OpenGL® texture quality level. Maximize overall OpenGL® performance by moving the slider to the left. Enhance overall OpenGL® image quality by moving the slider to the right.
Mipmap Detail Level slider This slider enables you to adjust the OpenGL® mipmap quality. Mipmaps are a set of texture maps of differing size and resolution used to represent a given texture. The texture map used for a 3D object is determined by the application, how close you are to an object and the Mipmap Detail Level slider setting. Maximize overall OpenGL® performance by moving the slider to the left. Enhance overall OpenGL® image quality by moving the slider to the right.
Wait for Vertical Sync This limits the frame rate of OpenGL® applications to the refresh rate of your display device. Selecting Always Off allows OpenGL® applications to run at their highest possible frame rate. Selecting Application Preference gives OpenGL® applications the ability to enable Wait for Vertical Sync. If an application does not specify, then Wait for Vertical Sync is disabled.
Compatibility Settings button This provides advanced settings for resolving incompatibilities with certain OpenGL® applications.
Defaults button Check this to restore the OpenGL® settings to default values.

Compatibility Settings

   
Force Z-buffer depth Enables you to explicitly set the Z-buffer depth. Most applications will work best with the Disabled setting.
Support KTX texture formats Enabling this feature allows applications to rapidly update segments of the screen that change very quickly. Most applications are not affected when this feature is Enabled.
Defaults button This button allows you to reset the OpenGL® Compatibility Settings to default values.
