Rosewill G03-ATI9000 user manual Direct 3D Compatibility Settings

Texture Preference slider

Selecting this decides whether your application should use high quality or high performance textures. Moving the slider to the right delivers the highest quality experience. Moving the slider to the left emphasizes a high performance solution while still providing good visuals.

Mipmap Detail Level slider

This will allow you to choose the texture quality of the mipmaps the application will use. Mipmaps are a collection of different sized textures of the same image. As the user moves closer to a 3D object the image quality should increase, requiring a higher quality texture of the same image. The base mipmap is the highest quality texture, and all subsequent mipmaps are smaller sized textures of the same image. Moving the slider to the right selects a higher quality base mipmap. Moving the slider to the left selects a lower quality mipmap.

Wait for Vertical Sync

Wait for vertical sync will lower the frame rate of full screen games but reduce the image tearing that can occur with the higher frame rate. Selecting Application Preference allows the application to decide whether or not it should display its frames at the refresh rate of the monitor. Selecting Always Off allows the application to run at its highest possible frame rate, regardless of the monitor’s refresh rate which is typically less than the frame rate at which the application will run.

TRUFORM

Truform uses High Order Surface geometry to generate more detailed and realistic terrain and character models for applications that support this technology. Select Application Preference to enable Truform. Select Always Off to disable Truform.

Compatibility Settings button

This button allows you to access advanced settings that can solve compatibility issues for a few specific Direct 3D® applications.

Defaults

This button allows you to reset the Direct 3D® settings to default values.

Direct 3D® Compatibility Settings

Support DXT texture formats

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.

Alternate pixel center

This may eliminate problems with some Direct 3D® 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.

Defaults button

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