CES or not, it's business as usual for Nvidia's driver team this week. The team has just posted a new set of GeForce graphics drivers blessed with certification from Microsoft's Windows Hardware Quality Labs. You'll find this 332.21 WHQL release here in 64-bit form and here for 32-bit users.
According to the announcement on the GeForce.com blog, these drivers include a bunch of new SLI profiles. Assetto Corsa, EVE Online (DirectX 11), Plants vs. Zombies: Garden Warfare, and Thief are all covered. 3D Vision profiles for Injustice: Gods Among Us and Path of Exile have made it in, as well. (The former is rated "Excellent," while the latter is "Good.") Oh, and Nvidia says the 332.21 WHQL release "ensures maximum performance and system stability across all titles"—but that's usually the case.
I don't see much else of note in the, uh, release notes. That said, it looks like Nvidia has squashed a number of bugs, including one that caused ShadowPlay to record 1080p game footage at the wrong resolution. You'll want to scroll down to page 15 of the PDF for a full list of fixes. (Thanks to TR reader SH SOTN for the tip.)
