All right, you probably know the drill by now. Nvidia has released a new batch of drivers bearing certification from Microsoft's Windows Hardware Quality Labs. You can grab the 331.82 WHQL drivers here for 64-bit versions of Windows and here for 32-bit systems. Desktop PCs running Windows versions from Vista through 8.1 are supported; laptop users and WinXP-running stragglers can find appropriate downloads through the driver search page on GeForce.com.
The 331.82 WHQL release is recommended for "all GeForce GTX users." It adds official support for a couple of new games—Assassin's Creed IV: Black Flag and Need For Speed Rivals—that were released earlier today. On top of that, Nvidia says the update includes "major" optimizations for gaming on 3840x2160 monitors. Users who ponied up for such displays can purportedly expect "up to 50% faster framerates" in games like Battlefield 4, Crysis 3, and Metro: Last Light.
Also included is version 1.7.1 of Nvidia's GeForce Experience software, which lifts the CPU requirement for ShadowPlay video recording. ShadowPlay is now available to "all GeForce GTX 600 and 700 Series users," Nvidia says. Check out our original ShadowPlay coverage for more details on the game recording feature works.
Last, but not least, the new drivers include updated SLI and 3D Vision profiles for Assassin's Creed IV: Black Flag, an updated DX11 SLI profile for Natural Selection 2, and a new SLI profile for Path of Exile.
