NVIDIA has made the latest version of its beta graphics card drivers available for download. With the new version 304.79 beta drivers comes TXAA support, numerous bug fixes, and the first unified Windows 8 and Windows 7 release.

We covered TXAA, or temporal anti-aliasing, in our NVIDIA GTX 680 2GB review. The new 304.79 drivers enable support for it in The Secret World MMORPG – following a game update. TXAA will come in two levels with TXAA 2 having quality greater than 8x MSAA, especially with in-game objects like chain link fences. The issue with TXAA adoption is that it must be implemented in the game engine, and cannot simply be added on after the fact via the NVIDIA control panel. Also, it is a feature that is exclusive to the company’s 600-series Kepler graphics cards.

There are a few other games that have claimed support for TXAA, but gamers will have to wait for a future update to take advantage of it.

The beta drivers are the first graphics drivers to be a unified release with support for both desktops and laptops running Windows XP, Vista, 7 and 8. Further, the company has updated its SLI profiles to support End of Nations, Nexuiz, Tom Clancy’s Ghost Recon Future Soldier, Tornado Force, and Tribes: Ascend. The release also addresses a number of bugs. Some of the larger bug fixes include a fix for an issue that caused the PC to reboot instead of shut down, an issue that caused a black screen after driver installation, and a fix for flickering mouse cursors when hardware cursor is enabled in certain games.

You can find the complete list of bug fixes in the release notes, and you can grab the latest beta drivers from the NVIDIA website.
