Nvidia has released a quick graphics driver update version 267.31 yesterday, after the 267.24 beat release the day before that. The new 267.31 driver has all the features of the previous 267.24 driver with just a single bug fix for users with GeForce GTX 580 video cards that have multiple monitors:
GeForce GTX 580 w/VBIOS 70.10.20.XX : In a multi‐monitor configuration, one display is blank.
So you can update to the new 267.31 Beta driver only if you are affected by this problem, otherwise you can stay with the 267.24 until an official WHQL release is made available. The 267.24/31 driver releases are needed for people wanting to play the 3D Vision-ready game Bulletstorm as well as playing the upcoming game Dragon Age II in DirectX 11 mode without issues.
