Recently I purchased Black Ops 2 off steam and when I first played it for a few days the frame rate was great and I was running on max graphics settings with no worries but in the last day or two the performance and frame rate of the game has decreased and I have no idea why (Possibly a wrong system update or graphics driver I installed?). I would update the graphics cards but I would want to make sure that I was getting the right updates and everything I need. Could someone please suggest some updates/downloads I should get and what action I should take in order to restore the initial performace? I have a feeling it has something to do with the drivers or graphics cards or something related, I just don't know what or how to fix it! ALSO After updating the Catalyst control center to 12.10 upon opening it has the error message "No AMD graphics driver is installed or the AMD driver is not functioning properly please install the appropriate AMD driver for your hardware... HELP!!!
