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-RX30S128D-B Graphics Accelerator - 26 • TRUFORMTM TRUFORM is a technology developed by ATI that overcomes the bandwidth and memory constraints of traditional 3D rendering software to produce the smoothest and most natural 3D images. TRUFORM not only enhances the smoothness, but also provides highly detailed lighting effects. This greatly enhances the realistic quality of 3D scenes by providing highlights on the surface of curved objects. TRUFORM can be set to favor either an increase in system processing performance or improved image quality. Setting for performance is best used for 3D images that do not require a high level of smoothness and lighting detail. Setting for performance is best used for situations where a high level of realism is required for the object's shape and reflective properties. • SMARTSHADERTM SMARTSHADER technology incorporates major advances in the area of Pixel Shaders, which are small programs that execute on every pixel rendered to the display device. With support for up to six textures in a single rendering pass, the memory bandwidth constraints associated with multi-pass rendering can be greatly reduced, which translates into better rendering performance. By doubling the maximum allowable length of the shader programs, more complex ef fects can be created to accurately model the visual properties of materials and surfaces, including hair, skin, wood, and water. English -27 -Software Installation • No Preview English The No Preview page combines all of the principal 3D features onto a single page, without any preview window, allowing for quick access and adjustment. You can change the settings for the following 3D features as you normally would on each feature own page: • Anti-aliasing • Anisotropic filtering • CATALYSTTM A.I. • Mipmap Detail Level • TRUFORMTM • Wait for vertical refresh • SMARTSHADERTM Effects This page is useful when it is not necessary to preview the adjusted settings because the effect is already known or understood. • API-Specific The 3D API-Specific dialog helps to select settings that are exclusively for the Direct3D® 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 are know which type of API (Direct3D® 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. GV-RX30S128D-B Graphics Accelerator - 28 Color : The Color page helps to adjust the color properties of your Desktop and Full Screen 3D applications and games. Use the Color Correction Images to e preview the changes before applying them. The Color curve is a graphical representation of all the values of gamma, brightness, or contrast. The color curve line will reflect any changes made to these elements. • Color Desktop 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. • Color - Full-screen 3D Adjusting the Gamma control alters the overall richness of color. Adjusting the Brightness control alters the overall brightness. Adjusting the Contrast control alters the overall contrast. Adjusting the Gamma can be useful for CAD applications that rely heavily on color coding or applications that require realistic color. Adjusting the Brightness and Contrast can be useful for 3D games that display dimly lit scenes. Video : With Video setting you can set for viewing video files: • Standard Settings Video Overlay Standard Settings offers video presets that are comprised of Home, Work, Theater, and Custom. Select a preset from the Video Presets drop down menu. • Overlay/VIDEOVISION Use this page to manually set Gamma, Brightness, Contrast, Saturation, and Hue. • Theater Mode Use Theater Mode to change the way you view streaming video. English -29 -Software Installation EnglishEnglish VPU Recover : VPU Recover enables the ATI display driver to detect when the graphics processor stops responding to display-driver instructions. When this happens, the display driver attempts to reset the graphics hardware. In most cases, VPU Recover will be able to reset the graphics processor without requiring a system restart. Should the computer be unable to reco...
