CUDA GPU not used

[Brian Murphy]

[James Robertson] “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: https://blog.krama.tv/hacking-adobe-premiere-cs5-to-enable-more-nvidia-cuda-... works!”

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

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?

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 1280×720 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.
