I recently tried upgrading AMD Catalyst 12.3 to the latest version (12.4), and despite the installation going well, there are a couple of nasty bugs. For one thing, the software still reports the version as being 12.3, and so will wrongly prompt another software update if you try checking for more updates.
More importantly, the new drivers have a serious graphical glitch when playing PotC:
A forum thread here confirms that this error has affected other games, so it will likely affect CoAS as well. I have since reverted back to version 12.3, and the graphical glitch has stopped.
My advice is to keep using the Catalyst version you are already running (12.3 or earlier), and do NOT upgrade to 12.4, at least until a fix is available.
