Nvidia's engineers sure have been busy recently! Just days after releasing a WHQL-certified driver designed specifically for the Windows 8 Release Preview, a new beta driver has landed in our laps today. The GeForce 304.79 beta drivers are important for a couple of different reasons: they're the first drivers to enable TXAA anti-aliasing as well as the first unified Windows drivers to integrate Windows 8 in with Windows XP, 7 and Vista. The drivers are promised to work with notebooks and desktops alike.
TXAA antialiasing wasn't enabled before for the simple fact that no games supported it. That changed today with the launch of "The Secret World," a new MMO by Funcom, though Nvidia's GeForce blog notes that the smoother textures won't take hold until the game releases an update of its own to activate the TXAA functionality. Another downside: only GTX 600-series video cards support TXAA.
Other than that, there isn't much. Some bugs were squashed, and the 304.79 drivers add SLI profiles for the following games:
End of Nations
Nexuiz (released at an earlier date via NVIDIA Update)
Tom Clancy's Ghost Recon Future Soldier (released at an earlier date via NVIDIA Update)
