ATI provides a utility to adjust the quality and performance settings that are used to make the most of the video experience. It does not matter what the application, quality and performance can both be set in this utility. The Catalyst Control Center is an easy-to-use interface that includes more than a few tabs to adjust preferences to the individual's tastes. Let's look at the options that are available.
Information Center: The Information Center gives detailed information about the graphics software and hardware. The display manager submenu allows for the configuration of the desktop environment. With two cards installed, the option of using four monitors is available and each can be configured independently. The display options submenu allows for a refresh rate overide as well as detection of the attached diplay devices.
Digital Panel: The digital panel tab features four submenus. Attributes gives some basic information on the monitor hookup up to the HD 3850. Avivo color is used to make color corrections and give control over the monitor color temperature. HDTV is used to identify the type of HDTV support that the attached monitor has available, as well as choosing the standard that will be used. LCD overdrive is supported in this Catalyst release.
3D:This is where you make all of the performance and visual enhancements that make or break the performance of the video cards. Anti-Aliasing, Anisotropic Filtering, MipMap detail, Catalyst AI, V-Sync and Adaptive Anti-Aliasing are all done through this tab. Here you will also find the OpenGL settings and basic color correction settings.
Avivo Video and VPU Recover: This tab allows for basic color adjustments and setting up of the theater mode for the display used with your system. VPU recover is a handy little tool that keeps you from having to reboot the computer if you have a video related issue. This feature comes in handy when overclocking the HD 3850 - or any ATI card for that matter - goes south. It allows for an easy recovery.
ATI Overdrive: Once opened, this feature must be unlocked to use. The standard overclocking of the hardware is not guaranteed and may lead to system instability. Warnings must be viewed and agreed to before using this utility. Here is where clockspeeds and temperatures can be viewed. Manually setting the 3D clockspeeds can be accomplished for the more advanced user while the Auto tune utility will test for you and attempt to find the highest overclock combination for the card(s).
Crossfire: This tab is for enabling or disabling the Crossfire configuration of the Diamond HD 3850 video cards. There is a warning about using the Catalyst A.I. in the advanced position and instructs the user on how to adjust it for optimal performance.
