• If you are unsure of how to configure anti-aliasing, use the Use application settings option. Your display will automatically adjust to the application's requirements. • Adaptive Anti-Aliasing Adaptive anti-aliasing is a technique that applies a combination of multi-sampling (MSAA) and super-sampling (SSAA) on 3D objects to improve edge smoothness and fine detail. This feature renders 3D objects containing transparencies more realistic, providing exceptional levels of image quality while maintaining performance. GV-R575 Series Graphics Accelerator - 20 Anisotropic Filtering .. .. Anisotropic Filtering is a technique that preserves detail on surfaces that have three-dimensional perspective and fade away into the background. It works best when used in conjunction with Mipmapping. Anisotropic Filtering can be set to favor either an increase in system processing performance or improved image quality: • Setting for performance is best used with applications that display objects with smooth, simple surfaces, like those seen in CAD applications. • Setting for quality is best used with applications that display highly detailed scenes, backgrounds, and textured objects, like those seen in 3D games. • If you are unsure how to configure anisotropic filtering, use the Use application settings option. Your display will automatically adjust to the application's requirements. CATALYST® A.I. Catalyst® A.I. makes use of ATI's new texture analyzer technology to optimize performance in 3D applications while maintaining or even improving image quality. 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. - 21 -Software Installation • 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. GV-R575 Series Graphics Accelerator - 22 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. - 23 - Software Installation • 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. • 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. 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
