The GeForce website now offers new version 334.89 WHQL-certified drivers for NVIDIA graphics cards. Here's word on the performance improvements these promise: "Today’s Microsoft-certified WHQL driver increases performance by up to 19% in over half a dozen titles. Gains were measured on the GeForce GTX TITAN, GTX 780 Ti, GTX 780, and GTX 770, but should apply to other GPUs also. (please note that results will vary depending on your GPU and system configuration)." Thanks Iggy.
