[QUOTE="Aridyme, post: 133597, member: 26204"] There are two separate technologies here, PureVideo and PureVideo HD. PureVideo is nVidia's MPEG-2 decoder. Like PowerDVD and WinDVD, it decodes MPEG-2 streams with or without GPU acceleration. PureVideo HD provides GPU acceleration of MPEG-2, WMV/VC-1, and H.264. It is a feature of certain Forceware drivers. Just having PureVideo HD doesn't accelerate your video playback though; you also need decoders that can take advantage of the feature. For MPEG-2 you need PureVideo, PowerDVD, WinDVD, or the like. For WMV/VC-1 you need Windows' WMV decoders. For H.264 you need PowerDVD (CoreAVC doesn't have GPU acceleration yet so it won't work). There are also a few other things to look out for. PowerDVD's implementation of H.264 requires SSE2, so if your processor doesn't have it it won't work. Also, WMV/VC-1 acceleration seems to be disabled entirely for AGP cards as of Forceware 8x.xx and higher, despite nVidia's claims that it works with Forceware 91.21 or higher. [/QUOTE]
