[RESOLVED] DGDecodeNV not utilising GPU?

[Giles]

Hi,

Apologies for coming here to unload my woes, but I've been idly poking at this problem with a stick for a while now and still haven't got to the bottom of the issue. Put simply, I've got everything in place, so far as I know, to use my GPU in the encoding, but everything I can see indicates that it's not being utilised when it runs.

My spec is Windows 7 x64, i7 930, 6GB RAM, MSI GTX570 Twin Frozr II plus GEForce driver v275.33 running 2 monitors.

I'm using the following as my basic AVS script as input to DGIndexNV (v2039)...

LoadPlugin("C:\Program Files (x86)\MeGUI\tools\dgindexnv\DGDecodeNV.dll")
DGSource("__vid__", deinterlace=1, use_pf=true, resize_w=1280, resize_h=720)

...which produces a file like this, as it should...

LoadPlugin("C:\Program Files (x86)\MeGUI\tools\dgindexnv\DGDecodeNV.dll")
DGSource("J:\Work Area\Tesrfile.dgi", deinterlace=1, use_pf=true, resize_w=1280, resize_h=720)

And as you have seen, yes, I'm being very naughty & using MeGUI. I appreciate that you don't support it, but what I'm trying to do here is at the very least to try to rule out anything that's been seen before or any stupid mistakes on my part before going elsewhere. I've cleared out my dgindexnv directory of everything but the script above, so there should be nothing lingering from any older releases.

When I open the AVS script that DGIndexNV generated in MeGUI everything looks fine, no errors or anything to be seen. I set the bitrate I want, add in the audio tracks etc and the jobs are queued up to go. I start the jobs running and indeed they do run. However, the tricky bit is that the CPU goes up to around 50% load and the GPU load (as seen in Afterburner and GPU-Z) sits there as idle as before I started, with zero signs of being stressed at around 14 or 15%.

At the end of the day, the output file I want is produced and is fine, but it is obviously taking a lot longer than I want. So...

1) Is there anything obviously wrong?
2) Are there any tests I can run or things I can enable/monitor for when it's running?

Thanks!

Actually, NVCUVID uses the VP engine on the GPU card for decoding, not the GPU itself (DGIndexNV uses the GPU itself for NV12->RGB conversion). So GPU load is an irrelevant metric.

Benchmark your card to determine its relative performance.

Ok. Will give that a spin this evening. I had expected some increase to show up somewhere on the card, but no change in temperature, fan RPM etc either, hence my concern. The biggest clue was going from a 260 to a 570 and seeing no increase in speed.

I thought that looked quite respectable, as the best of my scores, but then I saw someone running it on a Dell laptop and getting "84.08 | 146.16 | 135.67" and so I'm not so sure now.

Oh, and my system info...

The new VP5 engine is way faster. At the moment it is available on only a few cards, e.g., 520 and some mobile adapters.

That's just so bizarre, that a card you can pick up for forty quid is capable of outperfoming something costing five or six times as much. I'm almost tempted to fit one purely for encoding at that rate, if it weren't for the fact that more will follow before long.

It looks like I'm going to have to try encoding something with the basic DGDecode for comparison purposes
