It analyzes individual textures as they are loaded to determine the best and fastest way to display them. • Mipmap Detail Level Mipmapping is a texturing technique that preserves the detail on a 3D object's surface as it moves into the background. A series of low- and high-resolution texture maps are stored in memory and selectively used to create the object's surface, depending on what level of detail is needed. Mipmap detail level can be set to favor either an increase in system processing performance or improved image quality: • Setting for performance is best used when the 3D image is animated and smoothness of motion is the most important consideration. • Setting for quality is best used when high surface detail is required, especially if the animated object rotates or moves into the background. GV-R6900 Series Graphics Accelerator - 24 • All Settings The All Settings page combines all of the principal 3D features onto a single page, without any preview window, allowing for quick access and adjustment. This page is useful when it is not necessary to preview the adjusted settings because the effect is already known or understood. • More Settings Use the More Settings dialog to select settings for the Direct 3D and OpenGL Application Programmable Interfaces (API). These settings are provided for resolving certain incompatibilities within 3D applications that use one of these APIs. Use this dialog when you know which type of API (Direct 3D or OpenGL your 3D application uses, and you want to select a particular API-specific feature. If you are not sure which API your 3D application uses, consult the documentation of your 3D application. Note: The Alternate Pixel center Direct 3D setting is not supported on systems running Windows Vista. This setting corrected a corruption problem that occurred with some older games that should not occur with modern games. Color: Adjust the overall richness of color by using the Gamma control. To adjust the overall brightness use the Brightness control, and the overall contrast use the Contrast control. - 25 - Software Installation AvivoTM Video: • Presets To quickly adjust your video settings choose one of the video presets. Note: These settings will only affect applications with video overlay support. • Basic Color Use the Avivo Color: Basic option to manually set Gamma, Brightness, Contrast, Saturation, and Tint for video playback. Note: Certain video formats do not support these adjustments. These settings will only affect applications with video overlay support. • Advanced Color Use the Advanced Color page to fine tune the color of standard definition video (720x480) to make the color more or less vibrant and to remove excess red from skin tones. You can preview your changes before applying them. Note: This page is only for Windows Vista. GV-R6900 Series Graphics Accelerator - 26 • Basic Quality You can control the deinterlacing settings by checking the Use automatic deinterlacing item. The bar determines how the two interlaced video fields are converted into a non- interlaced form. Note: These settings will only affect applications with video overlay support. • Theater Mode Use Theater Mode to change the way you view streaming video. Note: •These settings will only affect applications with video overlay support. Extended Desktop Mode is not supported on systems running Windows Vista. •This item will be available when you connect two monitors. • All Settings The All Settings page combines all of the principal Video features onto a single page, without any preview window, allowing quick access and adjustment. This page is useful when it is not necessary to preview the adjusted settings because the effect is already known or understood. Note: These settings will only affect applications with video overlay support. - 27 - Software Installation ATI Overdrive: Use Overdrive to maximize your viewing experience by dynamically and safely overclocking the graphics processor and memory. Use the Automated clock configuration utility to obtain the ATI recommended speeds for the graphics processor clock and video memory clock. Alternatively, manually set these speeds to meet your specific requirements. Finally, Overdrive can be configured to run when the computer is booted or only when running 3D applications. Note: If your computer cannot restart after setting a higher clock speed, press and hold the
