NVIDIA Outs WHQL-certified GeForce Drivers for Windows 8.1 Preview
 

NVIDIA released some of the first WHQL-certified drivers for Windows 8.1 Preview, with its WHQL-signed GeForce drivers that are WDDM 1.3 compliant. Labeled GeForce 326.01 WHQL, these drivers cover all GeForce GPUs since 6-series, across desktop and notebook platforms separately (separate drivers for desktop and mobile GPUs). In its release notes, NVIDIA didn't list out any changes to the version from previous versions, but mentioned support for even the latest GeForce GTX 760 graphics card, so the support list is up to date.
