No need to reduce your setting, or worry about lower frame rates than you would want for say a first person shooter. A game like this does not need the lightning fast reflexes like a shooter and you realy wont notice low frame rates (at least above 30 ish). The graphics are beautiful in this game, turn your settings up, turn fraps frame rate monitor off and enjoy the game
EDIT:- I'm using a nvide 650ti (1g) and a lowest of the low athlon fx 4100 quad core, I get 30 fps min at max settings and never notice it.
