Nvidia has published its latest band of beta graphics drivers, giving GeForce owners a performance boost over last month's WHQL-certified release. Folks running the 280.26 drivers with GeForce 400 or 500-series cards stand to gain a 5 to 13% boost in a dozen or more PC games, including Call of Duty: Black Ops, Civilization V, Crysis 2, Dragon Age 2, F1 2010, Just Cause 2, Mafia 2, Metro 2033, S.T.A.L.K.E.R.: Call of Pripyat, and StarCraft II.
GeForce beta 285.27 also contains numerous 3D Vision-related changes, such as new game profiles for Aion, Diablo 3, Dead Rising 2: Off The Record, From Dust, Dirt 3 and others. It introduces support for viewing 3DVisionLive.com and YouTube 3D with SLI-enabled PCs, and it makes windowed mode the default viewing option for the 3D Vision Photo Viewer.

There are four bug fixes for Windows XP 32- and 64-bit: two pertaining to single-GPU configurations and two for multi-GPU setups. The first set are minor software glitches with Nvidia Update, while the latter pair seem more noteworthy. One caused a BSOD when playing Adobe Flash content at HD resolutions and then switching to fullscreen mode, while the other caused lousy performance in The Witcher 2: Assassins of Kings when using SLI.
