Time for a driver update, GeForce owners. Nvidia has released a new set of drivers that improves performance for a handful of games, fixes bugs, and broadens SLI support to new titles. The new 191.07 release is available through this page for Windows 7, Windows Vista, and Windows XP in 32-bit and 64-bit variants.
Compared to the previous Microsoft-certified drivers (190.62), the 191.07 set purportedly brings these performance increases:
Up to 12% performance increase in ARMA 2 Up to 8% performance increase in Batman: Arkham Asylum with GPU PhysX enabled Up to 50% performance increase in Call of Juarez: Blood in Bound with SLI enabled Up to 14% performance increase in Fallout 3 (indoor scenes) with antialiasing enabled Up to 10% performance increase in Far Cry 2 (DX9 version) with antialiasing enabled Up to 34% performance increase in Prototype with antialiasing enabled
Note the "up to" in the lines above. Nvidia stresses that the improvements depend on your system and software configuration, so don't expect any miracles.
Otherwise, the 191.07 release introduces OpenGL 3.2 support (an addition sure to thrill at least several developers), and it adds SLI support to games including Aion, Darkfall, Dawn of Magic 2: Time of Shadows, Dreamkiller, Fuel, Majesty 2: The Fantasy Kingdom Sim, and Need for Speed: Shift.
Nvidia has also thrown in some bug fixes, which you'll find detailed in the official release notes PDFs for Windows 7, Vista, and Windows XP. The company does mention one fix up front on the download page: cards that support multiple clock speeds will now correctly drop to their "2D" speed after exiting a 3D app. (Thanks to TR reader SH SOTN for the heads up.)
