Much more. i have been using 660 Ti release driver 305.37 since it arrived and it also unifies all Nvidia drivers including the GTX 560 Ti and the GTX 280 that i used in my latest VC evaluaton. If you have a newer game (and Shogun II has issues with exiting the game in some drivers), maybe try it. i am sure it is better for GW 2.
