NVIDIA Enables PureVideo on GeForce 6 GPUs

Final Words
Well, was it worth the wait? Considering that PureVideo came as a free feature on GeForce 6 cards, it's more like unwrapping an early Christmas present - one that we were promised eight months ago.
NVIDIA's image quality is pretty good for a PC DVD decoder, PureVideo delivered de-interlacing image quality that was equal to and in some cases better than what ATI brought to the table. And although we did not feature the comparison here, the NVIDIA PureVideo codec even offered better image quality than the latest DScaler 5 build.
Despite doing better than the competition, NVIDIA still is far from perfect with PureVideo. The Big Lebowski test was proof alone that there's still room for improvement.
The scaling quality and WMV9 playback were both quite competitive with ATI's offerings, although not strikingly better. With hardware acceleration enabled, WMV9 acceleration is promising and will greatly reduce the CPU requirements for high definition content playback.
Overall we're pleased with PureVideo, there's very little to complain about. We aren't as happy with it as we could have been, but we mostly have issue with the way NVIDIA handled the entire situation remaining quiet for far too long. Not to mention that there can't be too many happy 6800GT owners out there knowing that 6600GT owners will have lower CPU utilization when playing WMV9-HD files.
In the end, PureVideo is a positive feature for GeForce 6 owners, a verdict that we are glad we can finally give.

nserra: where do you get your info on mpg4 from?tfranzese - Tuesday, December 21, 2004 - link
I guess giving you the hardware features now means you should be entitled to the software to take advantage of it as well, huh?Those of you who think you're entitled to nVidia's DVD decoder are living in la la land. So now they should also give you the games that take advantage of their technology/features too?

Just don't buy an Nvidia card next time if you feel ripped off.You paid 'expecting' a feature to be 'fully' and not half 'assed' in to work 8 months late.
Protest with your WALLETS.
<-- never an early graphics adopter!
Still with my Nvidia GF4Ti4200 :P

Ati have MPEG4 encoding and decoding since 18/07/2002 so what do you want?
S3 Omni is better at video then Ati of Nvidia the problem is the rest.... even so, to bad there isnt an S3 in the tests.
I dont know why nvidia doesnt charge some buck or two for each chip/card it makes, so the feature get paied?
Unless this enconder software that they are charging, works on any card in the market, if its the case they are right in doing so.

Anand,I think you would do your readers a great service by retesting all of this on an AMD processor. Your Pentium 4 rig had Hyperthreading on, making this issue look far les serious than it is. Hyperthreading P4 chips report far lower CPU utilization numbers as opposed to even high-level Athlon 64 processors. So those of us with a Geforce 6800 who are running high-end AMD hardware are getting 70-100% CPU utilization in WMV9. It explains why a lot of us are having trouble trusting nVidia now, and in the future.

NVDVD =/= NVIDIA DVD Decoder, they are TWO DIFFERENT THINGSlink
http://nvidia.com/object/decoder_faq.html#othernv
Will this product work with NVDVD and ForceWare Multimedia?
The new software will upgrade the decoders in ForceWare Multimedia 3.0 to access the new features in the NVIDIA DVD Decoder. The NVIDIA DVD Decoder will not upgrade NVDVD 2.0 as it was a separate application based upon an old architecture.

Nice comparison of ATI and NVIDIABut still one thing is missing. I use cyberlink powerdvd for watching dvds. My question is that if i have got nvidia or ati dvd decoder. Should i use hardware accelerated decoder or should i stick with cyberlink decoder.
Cyberlink has implemented some smart software deinterlacer and image quality enhancer (CLEV-2). So i would like to see the image quality differences between hardware/software decoders available.

This sucks...ATI doesn't charge $20 for the claimed decoder/accelerator...
And they have the ATI HD component dongle too!

Bah, I would be kind of pissed if I had a high end $500 card only to find out now its more worthless than a sub $200 card at decoding video. A bit of shame on nVidia.Guspaz - Monday, December 20, 2004 - link
Oh, as a clarification of my previous comment (#41) I meant that I was under the impression that normally the DVD decoding software handled the de-interlacing, obviously PureVideo overrides that. But what I mean is on ATI cards, without any type of hardware de-interlacing, wouldn't the deinterlacing differ from decoder to decoder?
