Some improvements include new features such as PhysX processing for game-changing physical effects and performance boosts for many games vs. release 178. See link above for more details (after selecting your card and OS). Tried CoD4 last night and it ran as good as ever on maxed out settings (incl. hardware controlled settings such as AA etc.).

And for people that have the EVGA Nvidia cards, make sure you download the 180 drivers from EVGA, or the driver won't recognize your fan control or gpu control on the video card. I made this mistake multiple times.
