About ready for four days of overeating and gaming? If you have an Nvidia graphics card in your PC, then you might want to grab the latest GeForce driver betas first.
Posted earlier this morning, the new 331.93 beta release "ensures maximum performance and system stability across all titles," according to Nvidia. The company has added a new SLI profile for Assassin's Creed IV: Black Flag, as well, and it's ironed out "browser-related stability issues" that affected some GeForce 400- and 500-series GPUs.
The official release notes (PDF) mention another bug that's been squashed:
[Assassins Creed 4]: In a multi-player game, textures are either missing on models or they get swapped for each other. 
You'll find the 64-bit version of these drivers here and the 32-bit version here—assuming you're running a desktop PC with Windows Vista or newer. Notebook users or folks who are, inexplicably, still running Windows XP should head to the GeForce.com driver page to find appropriate downloads for their systems. (Thanks to SH SOTN for the tip.)
