NVIDIA released a new set of NVIDIA Forceware drivers today. One of the highlights of this release is the inclusion of NVIDIA's new PureVideo HD technology which provides hardware acceleration for decoding H.264, VC-1, WMV and MPEG-2 movies.
Movie lovers can now build a PC to enjoy a spectacular HD DVD or Blu-ray experience with the release of new NVIDIA Forceware drivers featuring NVIDIA PureVideo HD technology. PureVideo HD technology combines high-definition video decode acceleration and post-processing to deliver extraordinary picture clarity, smooth video, brilliant color, and precise image scaling for high definition movies. The drivers are available now from NVIDIA.com.

"This is a milestone in PC entertainment," said Scott Vouri, general manager of multimedia at NVIDIA. "NVIDIA is proud to be the first graphics processing company in the world to make it possible for consumers to build or upgrade a PC to play HD DVD and Blu-ray movies."
