Frederic BaumannCUDA GPU not used
by on Sep 29, 2010 at 9:08:56 pm

Hi,

I am trying to make Vegas Movie Studio Platinum HD 10 use my GTX 460 GPU.
So, using the Sony AVC encoder, with the check box de-activating GPU unchecked (so GPU should be activated), I start a rendering.

In parallel, I am running the TechPowerUp GPU-Z utility, which shows the GPU activity, and I can see that the GPU load is 0%!

So it looks like my GPU is not used while rendering - which might be true because rendering times are very close when the GPU checkbox is checked or unchecked.

I have also installed the TmpGenc 4 XPress software (a CUDA-enabled video encoding software), and it says that for GTX460 (and some other recent nVidia Cuda cards), version 3 of Cuda should be used instead of older ones. And when I do so, and encode videos with this software, then I see the GPU load increasing significantly.

Finally, I have read that Badaboom (another CUDA-enabled video encoder) does not support the same recent Cuda-based cards (the ones with Fermi architecture).

So I wonder if Movie Studio would not work only with Cuda version older than 3.

Any ideas???

Thanks for your feedback,
Frédéric

I believe CUDA with Fermi (GTX400 series) cards requires the newest drivers to work properly. If you don't have driver version 197 or later, try upgrading the drivers.

Hi,

I have made the tests with a 298.xx driver, which officially supports the GTX460.

I have also installed the beta 260.63 driver (supporting CUDA 3.2), and the GPU load still stays at 0% while rendering under Vegas Movie Studio Platinum HD 10.

Apart from this, I can get the GPU loaded at 99% with test CUDA samples, so the driver and CUDA seem to work properly, except for Sony Vegas Movie Studio Platinum HD 10.

So, if one could have any further suggestions, I would appreciate. I have no answer from the Sony support so far - I have asked them to confirm that the GTX 460 was really supported for CUDA-based rendering.

Thanks in advance!
Frédéric

I have the same problem with a GT240 based card. Other software is using CUDA (like Splash etc.). But not Sony Vegas 10 HD.

The "Magic Bullet" plug-ins make use of CUDA (so there is at least one benefit), but not Sony Vegas 10 HD. Another user reported that his GT220 based card didn't work as well.

Frederic, if you get a reply from the Sony Support would you please post it here?

Thank you.

Bad news, but interesting. Thanks!

Yes I will share the feedback.

Actually I received an answer yesterday, they say that they are not aware of Cuda issues with the GTX460 - but this does not say that they tested it. I re-asked my question once again, waiting for a new answer.

I got a replay from the support today (which did not really answer my question):

Thank you for your e-mail. Normally the acceleration using a CUDA GPU is just about 5 - 20%. But we are very interested in your opinion, so you can fill in our product proposal form:

I'm having the same issue with my GTX460, I see no appreciable gain in speed with CUDA enabled and I see no % increase in my GPU monitor's reading. However, I did notice that AVC rendering will crash after around 10 minutes of footage is encoded if I do not check "cpu only" in the AVC custom settings. There is definitely some sort of bug associated with this card.

I previously had an ATI card installed, but I did a complete uninstall and even purged registry settings and reinstalled Vegas to rule out any driver related issues.

Hello,

Not sure if you found a solution to this, but I think I have.

I looked at the posts of hacks to get unsupported cards working in adobe premier cs5, and oddly enough following steps 2 and onwards from this: http://blog.krama.tv/hacking-adobe-premiere-cs5-to-enable-more-nvidia-cuda-... works!

I monitored my graphics card with msi afterburner and it shows it using 30% gpu usage while previewing video.

Anyway seeing as this was the only site that came up when I googled for a solution, I thought I'd let you know what I'd found.

Cheers,
James

Many thanks James for this feedback. Actually, meanwhile I have switched to Vegas Pro, and I don't fully remember what was the outcome of my tests on Platinum. With Vegas Pro, I can see the GPU used at 10-12% when rendering to AVC/MP4 with the Sony AVC plugin.

At the time of my tests I evaluated Premiere Pro, and like you I had to apply the hack you mention to see Premiere Pro work with my GTX460.

What surprises me is that, as far as I remember, GPU CUDA acceleration is only used for AVC rendering in Platinum, so it should not be used during preview (unfortunately). Maybe the 30% workload you see applies to GPU-only, not CUDA (I am not an expert of nVidia cards, but I believe that there are other processing powers than the CUDA cores in a nVidia card).

I am not in front of my NLE PC right now, but I should have the time to make a test of what you recommend, on Vegas Pro tomorrow, and will let you know what I get.

Thanks again,
Frédéric

I'm evaluating Vegas MS HD Platinum 10.0 when rendering AVC. On a Win7Pro 32-bit system it isn't utilizing the Nvidia Quadra 600 cuda card (latest drivers from nvidia installed) as reported by CPU-Z under either "Render As" or "Burn Blu-ray" encoding.

I'm also evaluating Nero 10.0 (which similarly doesn't seem to use cuda for rendering except in the Vision 'export' process and I have a query in to them). I've sent a query into Sony. Hopefully they won't say 'we haven't tested the card yet' as I bought the card to accelerate encoding. In the meantime, I'll look into the steps James posted earlier in this thread.

Frederic, what was your impression of Adobe having used both? Is it worth the switch in time and effort?

Hi Alf,

In my case, rendering on Premiere Pro CS5 was twice as fast as Vegas Pro 10, for AVC/MP4 outputs. As far as I remember, all 8 cores of my i7 where fully loaded (only 4 with Sony Vegas Pro 10), and the GPU was also quite a bit loaded, as oppposed to Vegas Pro 10.

However, I find the GUI of Premiere Pro much less productive that the one of Vegas for editing tracks, putting clips on the time line, adding transitions and so on, and finally I chose to stay with Sony, considering that an effecient GUI was more time-saving than rendering.

I guess the under-optimality of the Sony rendering is more an issue of the AVC plugin, so maybe Sony might release a new AVC plugin doing more with the GPU (and with the CPU cores).

Hope this helps,
Frederic

The CUDA performance is rather disappointing. I just tried a GTX 460 Femi 768MB, and still couldn't get real-time encoding of 720p files with the Sony AVC codec. I even selected option to use CUDA. This is with a quad-core Q6600 at 3.0GHz. Perhaps Sony should look into adding support for the SpursEngine cards to help speed up encoding?

Hello Frederic,

I just bought NVidia GTX470 and have similar issues to yours. Have you forced CUDA to work well with Sony Vegas?


best

James, what specific program(s) did you enable for Vegas in the Nvidia Control Panel Manage 3D settings option and at the Program Settings tab? I tried "c:\Program Files\Sony\Vegas Movie Studio HD Platnium 10.0\VegasMovieStudioPE100.exe" as the program to enable, but that didn't fix anything (I'm trying this with NVIDIA Quadro 600 card).

Thanks,

Brian

Having improved my level of knowledge about Cuda, I am very surprised about James' post. James, if you read us, could you please give more details on what you mean by "it works"?

My concern is that, as far as Cuda starts working (even very little), as one can see during rendering, there is nothing more to do from control panels to enable it. It should either work, or not work at all.

In addition to this, access to Cuda from a program like Vegas is done through a Cuda-specific DLL, which is available (or not) whatever the settings entered in the nVidia control panel.

James, I would love to learn that I am misleading myself, so please let us know your comments :-)

Best regards,
Frederic

James,
I just did this on my GTX 570 (the hack you posted) and though it's not doing much, it is showing a 2% GPU usage as a render a mp4 file. Prior to your hack, it showed zero.

I have a 1 minute 1280x720 clip that I'm testing. I added some basic color correction to it, and running that through the Sony mp4 encode.

Before adding Vegas to the 3D settings, it was rending the clip at 5:19 and showing 0% GPU usage. Now it's rendering the same clip at 4:10 showing 2% GPU usage.

The math doesn't add up for me but it's rendering a little faster.

I'll also note that Vegas does not recognize CUDA regardless of my settings. But I did tell it to Render Using GPU If Available" even though it won't detect the card in the system tab.

I just bought this card today and have been very disappointed with the rendering times in Vegas 10. I also have a GeForce9600M GT running in a Mac, on bootcap / XP, and it renders faster in Vegas than this new card. The ATI card I took out was faster too (by about 30 seconds per 1 minute of rendering time). Very disappointing. I feel like something isn't working right somewhere. I've cleaned out all the old drivers, added new Nvidia, you name it. Nothing is helping.
