I say its messed up. Try to delete your cfg file couple times and than start game to see
is there eny different detection. I cant guarantee ideal result with my settup its depends which card are you using. My old card was 4870 and best settup was 1, 1 without touching
3d preformance. To change 3d preformace easly copy and paste some detected value to find your best, if you have 5850 or maybe 5870 try my settup ...good luck !
