Nvidia today made available the first set of WHQL-certified drivers from the 'Release 270' family of drivers (versions 270.xx to 274.xx) for GeForce 6, 7, 8, 9, 100, 200, 300, 400, and 500-series desktop GPUs, as well as Ion desktop GPUs. The release kicks off with version 270.61 and adds support for the newly launched GeForce GTX 590, 560 Ti, and 550 Ti graphics cards.
There are a ton of performance gains for GeForce 400 and 500 series GPU owners versus version 266.58 WHQL drivers. The most significant is up to a 516 percent boost in Dragon Age 2 (GTX 580 SLI 2560x1600, 8xAA/16xAF, Very High, SSAO on). There are several other situations in which Dragon Age 2 performance is obscenely increased, though depending on your setup, you can also expect an increase in framerates in Just Cause 2, Civilization V, Far Cry 2, Left 4 Dead 2, H.A.W.X. 2, Call of Duty: Black Ops, Mafia 2, and Metro 2033.
The latest drivers also flesh out Nvidia's 3D Vision support with new performance, bug fixes, and added features.
