For the record, ATI's Catalyst Drivers are RARELY buggy and usually perform without a hitch in most apps with every revision. For some reason my system didn't like 7.11 with GH 3. Not necissarilly 7.11 fault, but it was definetly a part of the problem.
For all I know it could be is a conflict between 7.11 and a process running in the background of my system when playing GH 3. Heck, it could have been just a bad install with some older driver conflicts. All I was saying is, I was too lazy to try to make it work as I knew it would work with 7.10's. And seeing as how nothing in the release notes made any difference to the games I was playing at the moment, there really was no sense in me spending time to get them up to code on my system when 7.10's worked perfectly fine.
ATI's driver releases, at least for me, are usually very stable and perform well, just some bad luck this time.
