Thanks guys, I had an old driver installed, I usually keep my computer in Hibernate when not using and only received Catalyst update when I restarted. Will try Max settings when I get home tonight. Seems to be working fine after driver update. Have not really had time to tweak all my settings, built the computer back in July for this game, but have not adjusted ll the stock settings yet. I guess I need to restart or shutdown at least once a week and start playing around with settings. Happy gaming!
