Ahead of its scheduled release, AMD's first Catalyst driver to include its ambitious Mantle API and TrueAudio, was leaked to the web. Notebook maker Toshiba listed it on its support site. That's the good news, and here's the bad news. First, the driver is packaged by Toshiba support to work only on its notebooks. You could experiment with the driver information file, if you know what you're doing. Second, its installer probably checks out your motherboard ID to tell that you're not using the software on a Toshiba notebook. On the bright side, it does leave installation files in your temp folder, including an AMD installer. If you're up to it, download the 316-megabyte installer from here.
