Rage3D Tweak is a multi-language Radeon Tweaker designed to fit right in with the other ATI option tabs in the Advanced Display Properties accessed through the Control Panel. It allows access to Registry Tweak options, Custom Display Modes, Refresh Rates, and Overclocking all through an easy to use interface. For those requiring instant access to all the tweak options, a handy icon on the task bar can be enabled for quick access to all three tweaker tabs. Comprehensive html, outline based help is available through the standard "?" icon in the display tabs and the help button.
Note: Version: 3.3 is for the Catalyst drivers ONLY! Not for older versions. If you want full functionality with Pre-Catalyst drivers, then continue using Version 3.2(which is still available for download from the r3dtweak page).
