Hello, i have a problem with my hd7850 OC..i played assassin creed 3 on high setting..but when i set anti-aliasing into very high setting, i can see the spiky line occur at the edge of the object..not screen tearing.. very serious spiky/colourless line..but the gameplay still smooth..is it my gpu faulty??

its a driver problem, wait for better ati catalyst drivers to come out and apply patches to the game
