Hey can anyone help me, im trying to figure out how to turn on catalyst ai so that both my gpu's on the 5970 are active. I see the setting in the CCC under gaming and 3D Applications. I go to catalyst AI and i can change the texture filtering quality from performance to quality, and there is also a check box for enable surface format optimization, but there is nothing that specificly asks me to enable this. I've tried everything (using full screen also) and I can't get both my gpu's to actively work; Any ideas?
