and the 12.7 CAP 3 Which has settings set by ATI for some games that improve performance even on none xfire systems these work automaticaly as you load the game such as ROF.
Forget trying to Instal/uninstal driver through control center.
Once downloaded run the 12-8_vista_win7_win8_64_dd_ccc exe file and select uninstal and then custom.Select all the from the list with the
exeption of the chipset driver or the ahci driver .Run and restart ,when the system boots press F8 and run driver sweeper and uninstal any video drivers listed from ATI/AMD.Re-boot and run the 12-8_vista_win7_win8_64_dd_ccc exe file again which yo will now find on C:/AMD/support/12-8_vista_win7_win8_64_dd_ccc_whql/setup.exe.
Run the programme again and select instal and tick the lot.Anything you dont use wil not effect performance.The exe will instal the drivers then you can re-boot.Run the 12.7 CAP 3 & re-boot.Deferag only if you do not have and ssd hard drive.AMD VISION Control center (CCC)icon can be found in the windows taskbar programmes by the taskbar clock.Hope this helps.
