has rolled out its WHQL certified 257.21 Geforce driver with support for Geforce 6, 7, 8, 9, 100, 200, 300 and of course, the 400 series graphics cards as well as the ION GPUs. The new version of the Geforce driver is, as expected, all about Geforce GTX 400 series and brings numerous new features as well as performance improvements for the noted series.
The highlighted features include support for OpenGL 4.0 for Geforce GTX 400 series GPUs, support for CUDA Toolkit 3.1, support for the new extreme Antialiasing modes on 3-way SLI including the up to SLI48x AA on Geforce 200 series and SLI96x for the GTX 400 series, support for a new "Quality" mode for Ambient Occlusion, new Control Panel setup page for SLI and PhysX on multi-GPU systems, and new Control Panel feature for CUDA GPUs.
The new driver also brings support for Blu-ray 3D with Nvidia 3D Vision technology, something that the latest beta and WHQL drivers lacked.
The performance improvements include various games like Aliens vs. Predator, Batman: Arkham Asylum, Battleforge, Far Cry 2, S.T.A.L.K.E.R.: Call of Pripyat, but the most noticable one is the 40 percent improvement in Metro 2033 with SLI setup. Performance improvements are also visible in Unigine: Tropics and 3DMark Vantage benchmarks at certain resolution and settings.
