Hey, are you aware that you can easily get rid of the watermark? It's caused by a hash in /etc/ati/signature. Without a valid string in that file, it displays the watermark. With the beta drivers, it ships with the word "UNSIGNED" in place of the signature. Simply copy the string from the last release and it will work without the watermark. For example, I'm (still... haven't upgraded yet) using the 13.3 beta, and simply used the string from the 13.1 release. I wouldn't normally use a beta, but it was easier than adapting patches to get the back end to compile with Linux 3.8.x.
