Here is the poll fivefeet8 suggested in the other thread I started.

Here is the previous thread where I asked about programs for the OVP.(onboard video processor)
http://www.nvnews.net/vbulletin/showthread.php?t=37673&page=1


T2 HD Clip 72-87% CPU usage, stayed mainly around 78%.

Step Intio Liquid 90-99% CPU usage, stayed mainly around 95%. Dropped a bunch of frames as well.

*Edit*
Here's a couple of reviews of the 6600 that bpt8056 posted. The 6600 has the OVP as well and if you look at the reviews it seems to work on the 6600.

One of the reviews used the T2 HD clip for testing. We could use that or the "Step Into Liquid" 1080 clips for testing purposes.

would be nice if we had a test that told us if it works or not.

Really how am I supposed to know if it works or not?

Updated with a little more info plus a link to test clips.

I said yes but only based on the "Step Into Liquid" trailer from Microsoft. It supposedly taxes your CPU heavily. I got around 40-45% CPU usage showing while others said theirs shows 90-100%.

I'm not an Intel guy so don't flame me for asking but is there a way to disable HT? So far almost all, if not all, the guys running Intel HT processors don't have their CPU's maxed because it seems like HT helps ease the CPU load.

If it can be disabled, try playing the clip with it disabled.

HT is disabled in the bios.

That shouldn't be taken as flame bait so don't worry. I had the same question since I'm running on an HT. When I get home and have some time, I'll disable HT in my BIOS and try it out.

I don't think its the Video processor not working but rather Media Player. When I ran it with Media Player it was 100% CPU usage and choppy as hell. When I used Nero it was only 50-60% usage and ran smooth.

I ran it in Nero Showtime and the CPU usage never went below 97%. It mostly stayed at 99%. The video didn't seem to have dropped frames but the audio had a lot of pops and noise plus went out of sync with the video.

DId you enable hardware acceleration in Nero? If not enable it and restart your pc.

Well if im correct and I am sure I am us with non-working on-chip video processors are entitled to a refund or a working replacement. I would just hope if I get my EVGA 6800NU the one id be getting back allows me to open pipes like my current one.

With my Ultra running the T-2 1080i HDWMV9 trailer I am only showing 20-33 percent CPU usage. I am also running the video in it's native 1920X1440 resolution but that should not effect CPU usage. I did not check out the Liquid demo yet.

Ok tried that and had the same results.

On my 6800 ultra, the Liquid demo doesn't drop frames and is smooth, but hovers in the 80-100's. Hm.. I'm gonna run the T2 HD video and see.

I also noticed that Xbit used PCI-E variant of the 6600gt and 6800gt. Maybe the PCIe interface makes a difference in the efficiency of the hardware video encode/decode. But still, it shouldn't be close 100%.

Edit: Running the T2 HD video, my CPU usage was around 60-70%. Still quite high it seems.

100% cpu usage. Also the clip was very messed up. I am using SP1/WM9, dont know if thats the problem, but the picture was very bad. Also 100% usage.

65.73 drivers

Am i doing something wrong?

Ok just got WM10, 75-97% usage on that test, how ever some of the other ones sit in the 40-50 zone.

The VPU on my BFG 6800 (nu) does not work. I use Media Player Classic to play the T2 (1080i) trailer. The cpu usage hover around 84% to 92% and it dropped around 300 frames; lots of jitter. I tried this on driver 61.77, 65.76, and 66.81. The results were the same on all.

I had look forward to the 6800 feature of HD video decoding. My cpu (2.4 P4) is not fast enough to cleanly decode HD video without stutter. To me, this feature is as important as the 3D acceleration.

It's funny how NVDIA used to tout On-Chip Video Processor feature for the 6800 line, but not anymore. Check out their 6800 page:

http://www.nvidia.com/page/geforce_6800.html

But it's still on the 6600 page:

http://www.nvidia.com/page/geforce_6600.html

I wish ATI has something comparable to the 6800nu 3D prowess and the same price range.

same for me...doesnt seems to work......my cpu usage is 15 tp 10 % when i watch divx movies.....i tried different drivers but the cpu usage is same.

Okay I'm new here and I basically came here looking for information about the Video Processor. I've been using WMV-HD for a some time and own many WMV-HD DVDs and here is what I know. WMV-HD is very intensive on the CPU so without hardware acceleration it will tax your CPU. However a high end CPU should be able to use it without problems. But even without h/w acceleration you should get 50-60% CPU usage on a high end 3GHz equivalent CPU (if not then there is something else wrong with your computer). For example on my AXP 3200+ computer without video acceleration I get around 50-60% CPU Usage (for 1080p videos). Now using the 6800 it should be lower than that. However I find that it isn't so. It still gives around 50% usage with my 6800 GT. I have seen reviews where the video acceleration was working (on a similar 3GHz level CPU) and the CPU usage was around 20-30%.

So bottomline: Unless you are getting around 30% CPU Usage with about a 3GHz level CPU, the video processor is not working.

So for me it doesn't work and it looks like nVidia has some explaining to do. I own a PNY 6800 GT BTW with the latest 66.81 drivers.

If its not working why does Nero use only 60% when Windows Media player uses 100%. Like I said it sounds like a windows media player problem to me.

I get similar CPU usages(80-100%) using WM10, PowerDVD, Nvdvd2.55, BSplayer, and Divx Player. The lowest CPU usage I've measured was with NvDVD 2.55, but it wasn't that much lower than the others. So it might not be a Windows Media Player thing. I'm thinking it might be a Pci_e/AGp thing.

We definately need someone here at Nvnews to do some investigation into this matter.

The Video hardware processor is still listed on the 6800's tech feature list.

I've also run the T2 HD 1080p video clip. If it's the same one that the Hexus article used, then the Hardware video decode seems to somewhat be working. I'm getting about 60% CPU usage compared to their Nv40 which was getting close to 100%. Hmm. Strange.

Here is some discoveries I've found. Playing a DVD of "We Were Soldiers", I disabled/enabled hardware accelleration from the Forceware Multimedia Properties options. I played the DVD with WMP10. These are my results of playing a clip from the DVD:

Hardware Enabled
Lowest CPU usage: 13%
Highest CPU usage: 29%

Hardware Disabled
Lowest CPU usage: 24%
Highest CPU usage: 35%

I then played the same DVD clip on Power DVD.

Lowest CPU usage: 8%
Highest CPU usage: 24%

So it seems the Hardware Video decode is working somewhat for DVD movies. I'm beginning to think that the AGP versions of these cards are the ones having problems. Maybe the PCI_e bandwidth helps with the HD video decode.

"So it seems the Hardware Video decode is working somewhat for DVD movies. I'm beginning to think that the AGP versions of these cards are the ones having problems. Maybe the PCI_e bandwidth helps with the HD video decode."

As I understand it, hardware has helped with MPEG 2 decoding for quite some time - not just with the NV40 range, so I'd expect pretty damn low CPU when decoding DVD. It's MPEG 4 decoding that's at stake here.

PCIe *could* actually be the cause here. Hmmm.

For the peeps running AMD systems and having stuttering problem running these vids. Try enabling Fast Write.

I downloaded the Living Sea 1080 version and the vid was stuttering with 99~100% CPU utilization.

Curious, I went to the MS site I downloaded from and there's a link that goes to futuremark's app that will analyze your system. I did that and it told me my system might not be able to run the clip because Fast Write is not enabled.

So I went into the bios to enable fast write, restarted, came back to play the vid. This time, smooth playback with 60% cpu utilization.

Give it a whirl and see how it works out for you.
