NVIDIA have released a GeForce 304.48 beta driver for it’s graphics cards.

This is what NVIDIA have posted on their blog:

The new NVIDIA GeForce 304.48 beta drivers are now available to download. Featuring performance improvements of up to 18%, the 304.48 beta drivers also include user experience enhancements and a number of new NVIDIA Control Panel enhancements for titles such as Diablo III, The Secret World, and L.A. Noire.

Performance Improvements

The GeForce 304.48 beta drivers include new performance optimizations that give all GeForce 400, 500, and 600 Series users faster frame rates in some of the most popular titles, giving gamers an even better experience.

In addition to improving performance in the aforementioned titles, the GeForce 304.48 beta drivers also fix a bug introduced by the latest Shogun 2: Total War update that reduced frame rates by up to 60%. If you were previously struggling for performance, jump back in to Creative Assembly’s strategic masterpiece and give the game’s engrossing campaign and multiplayer mode another shot.

User Experience Enhancements

The reaction to NVIDIA Control Panel FXAA has been fantastic. Gamers are enjoying jaggie-free games without the massive performance impact of MSAA, and are taking advantage of the feature in games that lack anti-aliasing options. However, when users enabled FXAA globally they found that certain applications, like Windows Live Mail, were being anti-aliased also, making text unreadable. To rectify this issue we are now disabling FXAA’s use in the programs identified, but if there are more that need blocking do let us know and we’ll add them to the exclusion list also.

On the GeForce GTX 670, 680 and 690, some users identified an occasional micro-stutter when gaming with VSync or Adaptive VSync enabled. For most this wasn’t noticeable, but we take any issue that detracts from a user’s enjoyment of our products very seriously, and have introduced a fix that will improve the smoothness of VSync gaming.

When using GeForce 3xx drivers and factory-overclocked graphics cards from our partners, some users received poor levels of performance, a result of the graphics card’s clock speed being reduced to idle levels. As with the VSync issue above, this problem is also rectified by the new GeForce 304.48 beta drivers.

NVIDIA Control Panel Game Enhancements

With the release of the GeForce 304.48 beta drivers we are enabling NVIDIA Control Panel Ambient Occlusion support in Star Wars: The Old Republic, and Multisample Anti-Aliasing support in Diablo III, L.A. Noire, Rayman Origins, and The Secret World.

Below, you can check out an example of MSAA in Diablo III.

The benefits of Multisample Anti-Aliasing cannot be seen with the naked eye in a static, fullscreen Diablo III screenshot. Instead, take a look at this enlarged comparison, showing a significantly reduced level of aliasing when 4xMSAA is enabled. Furthermore, MSAA overrides Diablo 3’s post-process anti-aliasing blur, allowing you to see the game’s textures as designed by Blizzard’s artists. Specifically, focus on the Waypoint’s artistic flourishes and its shiny, specular edges that are now more vibrant. In motion the impact of this change is dramatic, and especially so in the later, more colorful chapters.

To enable MSAA in Diablo III, navigate to ‘Manage 3D settings’ in the NVIDIA Control Panel, select the ‘Program Settings’ tab, select ‘Diablo III’ in the dropdown, and customize the settings as shown in the example below. If you cannot locate the Diablo III entry, click ‘Add’ and navigate to the Diablo III .exe, located by default in C:\Program Files (x86)\Diablo III.

Note: CSAA is even better at removing aliasing, though it also removes important in-game visual effects, and as such 8xMSAA is the maximum value we recommend.

And if you haven’t already, enable Ambient Occlusion for deeper, richer shadows, as detailed here.
