i cant, res scaler is the biggest fps killer for me on my gtx660ti. i even overclocked it by 10% and it still runs bellow 30fps.
best result for me is everything lowest setting without touching the resolution scaling, AA on low (this gets rid of the weird blurryness) , textures on max, world tile buffers max, post processing max. that way it manages to maintain a measly 30fps
