dual gpu- not what you think

[IPopov50]

OK, captain. Rolled back driver to 197.45, verified in device manager. AV off, firewall off, encode to dv9 1080p, no change 0% CPU load, 0% mem useage, just as before.

And speed is 1.95 Mb/s right?

[drobo]

Yes, at most. It always starts out fast but settles down low about 2 to 3% in.

[IPopov50]

OK, can you do me a favor, can you go to GPU Monitor Settings and tell me what Graphic Adapter it set for, and can you change it?

[drobo]

Graphics adapter is set to GeForce 9800 GT which is what I have. No, it is not changeable.

[IPopov50]

OK, one more thing. Please play any movie with any player on your computer and tell me what GPU and memory usage?

[drobo]

Playing movie with Media Player Classic Home Cinema. GPU load is 0% and Vmem is 0%. In the lower left corner of the player it says "Playing [DXVA].

[IPopov50]

Well, congrats... your GPU monitor can't read this card. So, you can't really say load on your GPU. I can tell that your card is participating in conversion process, your CUDA is working, I just can't tell you on which extend. You CUDA is working and that's the fact, there is no way you would get this speed with your Core2Duo on VC-1 content. (1.95 MB/s is about 12-15fps). For sake of experiment, if you don't mind, please do couple of things to see things in perspective:
(1) Please find AVC source, not VC-1 and see what speed it will produce
(2) Set every setting in A/V Codec to "software" and see speed then.
Would you do it for me, please!!

[drobo]

Bingo, Captain. I set everything to software and processed the same MPEG4/AVC movie as before and after 2% in the rate settled at 0.73 MB/s. I turned back on CoreAVC, CUDA, and CUDA+Software and ran the job. After about 2% in the rate was 2.17 MB/s, a three fold increase. Strangely, I even turned on nVidia's system monitor during the final run and it showed no GPU useage on their own card. Odd, hey. So there is a nice performance increase but I don't know how much is due to CoreAVC or CUDA but the important part is an increase. Now, the challenge becomes to find a GPU monitoring app that can read this card. BTW, apologies offered for frustrated sniping.

Thanks for your patience and help

I wonder what happened to apocracy the member who started this thread as it looks as if they just posted and left. Wonder if they learned from what was done here

[drobo]

Sorry. I know I hijacked this thread somewhat but I still think most of it was relevant. Because I own one, I do know the GeForce 8800 GTX does only CUDA encode or decode, but not both, I can't remember which. DVDFab does not recognize it. I just could never figure out why DVDFab wouldn't recognize it for whichever process it does do.

[IPopov50]

drobo,
I hope you have change your opinion towards DVDFab, and that was my goal. I have almost unlimited faith in DVDFab and ready to defend it using any means (including my patience
Please forgive me, I knew that your CUDA is OK from your post #7 where you said your speed was 1.95 MB/s, I just wanted you to come to this conclusion on your own. I was puzzled (still am) by the fact that your card lacks capability to communicate with monitors. I have read a few forums, and I think on Guru3D forum I have read that earlier cards do not have built-in sensors reporting capability, nor (some of them) because of that, do not have variable speed fans. Anyway, it's not important at this point.
Now, if you really want to see difference between CoreAVC and CUDA - take AVC content and run it with (a) CoreAVC set for H264 and (b) CUDA set fir H264. Leave everything else intact. You can go even further and set your encoder for "software" and create "clean" environment for CoreAVC/CUDA decoder.
BTW, all cards are enabled for both CUDA encoding and decoding, only lower-performance cards (like 8 and 9 series) can't keep up with the process. That's why DVDFab developers recommend to use acceleration only with encoder. Your settings I found optimal for your configuration
So, you are good for now... I hope you wouldn't jump to conclusion before you get all facts together anymore. Thx for your patience and willingness.
And hey, don't be a stranger, visit forum and participate in discussions

i ended up taking the nvidia card out because dvd fab would not let me turn on any cuda functions

It's because there's nothing to turn on. Your card isn't CUDA enabled, that's it.

[apocracy]

according to nvidia it is

[IPopov50]

If you do not have CUDA option in any of the A/V Codec settings, your card is not CUDA. Period. You can talk to nVIDIA and ask them a question. However, I do reserve right to be wrong though
I wish I'm wrong, really...
