“The GeForce 6800 models featured the 1st generation of our programmable video technology which includes support for high-definition MPEG2 video decode and standard definition MPEG2 encode, as well as advanced post processing features such as motion adaptive de-interlacing, and inverse 3:2 pulldown. The GeForce 6600 models have the same 1st generation programmable video technology support as the GeForce 6800 models. However, the GeForce 6600 models also include hardware acceleration for high-definition Windows Media Video (WMV) decode,” said Luciano Alibrandi, a spokesman for NVIDIA Corp.
While NVIDIA now says HD WMV acceleration is only supported by the GeForce 6600-series graphics processing units, X-bit labs has found that at least on some drivers the HDTV acceleration works on the GeForce 6800 GT PCI Express graphics cards. AGP flavour of the GeForce 6800 GT did not provide HDTV hardware decoding on the same driver version.
“In order to utilize the programmable decode and advanced post processing features of the GeForce 6800 and 6600, end users need to download an updated ForceWare driver as well as the NVIDIA DVD decoder. The ForceWare driver will be available shortly on the NVIDIA.com and the NVIDIA’s DVD decoder is already available for download from NVIDIA.com. For Windows Media Video decode on the GeForce 6600 models, end users will also need to download an update to Windows Media Player from Microsoft,” Mr. Alibrandi added.
, Alguem sabe alguma coisa disto? Tem só a haver com as capacidades de advanced encode/decode, correcto? Não afecta o desempenho 3D, que é o que mais me interessa
