Nvidia has released a new WHQL certified Geforce driver, version 186.18. It comes with v9.09.0428 PhysX, something that was already seen in 186.08 beta and features support for Geforce 6-series and up, as well as its ION platform, aka Geforce 9400. The new driver is basically the same as the previous one except for the fact that it fixes some bugs under Windows 7 OS.

It comes with all the features that were launched with 185 version of drives so you can expect support for Ambient Occlusion, CUDA 2.2, and expanded GPU hardware acceleration for Nvidia's Video Encoding library to GPUs with less than 32 cores.

It also brings certain performance boosts for Chronicles of Riddick: Assault on Dark Athena by 25 percent, 22 percent in Crysis, 11 percent in Fallout 3 with antialiasing, 14 and 30 percent in Half-Life 2 engine games with 3-way and 4-way SLI, and up to 45 percent in Mirror's Edge when antialiasing is enabled.

Nothing really new here unless you are running Windows 7 and want some bugs squished. You can download the new driver here.
