This small utility will allow you to disable/enable ATI’s Chuck Patch on-the-fly. This utility will make your life easier because you will not have to download the entire Chuck Patch driver, nor will you have to uninstall/reinstall your driver to obtain Chuck Patch’s features. With this utility the difference between the Chuck Patch and normal Catalyst is just a simple restart as opposed to a full download, install and reboot.
