I'm looking to update my drivers from 11.2 to 11.4preview. Problem is that I can't uninstall 11.2 drivers. They don't show in Control Panel -> Program and Features. The only ATI or AMD listed is the ATI Install Manager. When I open CCC it lists 11.2 driver but no op0tion to uninstall. Any help. I have been getting horrible 3d Mark11 scores and not the best performance all around. Computer is listed in sig. Thanks for any help.
