has released the first 270-family GeForce drivers with Microsoft's blessings. The WHQL-certified 270.61 update is largely comprised of the changes we saw in the previous 270.51 beta, including a massive 241% to 516% performance optimization for GTX 560 Ti and GTX 580 owners running Dragon Age II with specific high quality settings.
In certain configurations, both cards also get a 4% to 19% improvement when playing Mafia 2, Metro 2033, Left 4 Dead 2, H.A.W.X. 2, Civilization V, Far Cry 2, Call of Duty: Black Ops, and Just Cause 2. Although no specific gains are mentioned for GeForce 400 series products, Nvidia says the latest update contains minor tweaks for last-gen cards, so don't be surprised if you see a slight boost.

GeForce version 270.61 also brings an "Nvidia Update" feature that notifies you when new drivers are available and directs you to the download location. Although this isn't as streamlined as Steam's solution for AMD Radeon owners, it's a step in the right direction. Nvidia 3D Vision and 3D Vision Surround users will want to skim the release notes (available on our download pages above) as there are tons of new profiles and other updates.
