Some notes.. please correct me if I am wrong:
Purevideo nvidia drivers require Vista at the moment and will not accelerate under XP.
I hear getting x.264 to decode properly with mkv files are an issue right now. I think its the splitter?? |
PowerDVD v7.3 takes advantage of the PureVideo HD H.264 decoding in _both_ XP and Vista, even in .mkv, or whatever else uses x.264/H.264/AVC encoding, with no artifacting or anything. No matter what you hear, CoreAVC looks just fine, and FFDshow works fine, but is slow. I used to use CoreAVC until I got PowerDVD v7.3, and now I just use the Cyberlink decoders.
The big thing about the newer Nvidia 8500/8600 cards is that their newer Video Processors (often referred to as VP2), decode so well, that they do most of the work of decoding, and don't require a high end CPU. Only the midrange 85/86 GeForce 8 cards have this new VP2, not the 8800. It has the older VP, which isn't as effective.
