No CUDA acceleration from GTX 780 Ti - Premiere Pro CC & After Effects CC ?

Hi,

I recently upgraded my computer to accomondate my move to Adobe CC on PC:

  • Windows 8.1 64-bit
  • Latest Nvidia drivers
  • Intel i7 4930K @ 4.5GHz
  • 2x GTX 780 Ti SLI
  • 32GB DDR3 2400MHz RAM
  • 2x SSD Vertex 2 60GB @ raid0

When I'm rendered clips using both Mercury Playback Software Engine Software Only and Mercury Playback Engine GPU Acceleration (CUDA), the program behaves exactly the same and it takes the same time to do the rendering.

Exporting a 6 minute clip takes well over 2 hours to render - which obviously cannot be right.

Is there a setting I'm missing?

Any help is greatly appreciated!

BR

    Hello Jeff,

    I've made a new small clip for testing purposes. It consits of a standard Canon 5D mk iii .mov clip: 1280*720, 50fps. It is 28 seconds long ->243MB file size

    I crop it in Premiere Pro, slow it down to 50% speed and ad a simle mp3 soundtrack. The exported clip is now 36 seconds long. No filters or other effects added.

    It takes approximately 25 seconds to render it on either CUDA or software engines. Turning SLI on/off also make no difference. Looking at the taskmanager/MSI afterburner, there are no movement on my GPU's but the CPU utilizes all six cores @ 50% - 100%.

    A small clip like this should be done more of less instantly I think, but it's way better than using my project clip which uses effects, scaling etc.

    Please tell me that Adobe is going to have something for this card soon (GTX 780 ti). Thank you Adobe

      They won't mention support for specific cards in any upcoming version of Pr; it's not how Adobe works.

      If you want to use the cards, use them.  Remove the cuda_supported_cards.txt from the Pr and AME directories if you want to use the cards without the warning dialog popping up.  Whether you remove the file or not, the card will work fine.

      Thank you so much Jason. It seems that I have to upgrade to CC to get it to work. Mine is greyed out in CS6 . I have a friend who is a professor at UNLV and he will let me be part of his account this July when she rolls her Adobe CC over again..So i'll be good come July. Thank you so much for responding to me. God Bless

      Thank you for your link, John. Much appreciated.

      From what I can read and understand, Adobe does not certify the GTX 780 Ti for use with Premiere Pro CC and After Effects CC, and I find that extremely strange from a business point of view.

      We use the entire CS6/CC range of programs, and we recently made a significant investment into hardware to get us up to speed with the latest and fastest. This includes the Nvidia GTX 780 Ti. There are a lot of us out there with the latest hardware using Adobe's products, and we're stuck with the Mercury Playback Software Engine Software Only.

      Rendering clips is virtually pointless on our brand new hardware and it takes 10x longer now than on the old hardware... This effectively forces us (and a lot of others) to move away from Adobe's products - which is unfortunate as they are so good!.

      Perhaps I was to fast in assuming that a large coperations as Adobe would be on top of their certification process.

      Anyway, I now have a major problem to address: How to replace Premiere Pro and After Effects. Any suggestions?

      Best Regards

      Hi Kevin and thanks for a very quick reply,

      I saw this post previously:

      There has been a change in how we address officially unsupported cards in Premiere Pro CC.

      If your card meets all other requirements, the biggest being 1 GB of dedicated VRAM and up to date drivers including CUDA specific drivers on some machines, and Premiere is up-to-date, then the system will detect an unsupported card that may still work and prompt you with a dialog that says you can turn on CUDA acceleration at your own risk.  This way you do not need to wait for us to officially add your specific card.

      I'm running two ASUS GTX 780 Ti reference design cards in SLI on an ASUS Rampage IV Extreme Black Edition LGA 2011 motherboard, and I'm not getting any dialog box message saying Premiere Pro (or After Effects) is detecting my cards. When in After Effects and entering Edit -> Preferences -> Previews I can click on "GPU Information..." and here I can select the tickbox "Enable untested...acceleration" This is the only place where I get some kind of warning about using my GPUs.

      In Premiere Pro, under Project Settings, I can select Mercury CUDA, not no warning appear.

      Am I missing some other settings perhaps?

      Finally, it doesn't matter which setting I use; CUDA or software - the rendering time is still the same.

      Thanks,

      Andreas

      Andreas,

      Perhaps you previously clicked through the warning dialog box in Premiere Pro? If you see an option for Mercury Playback Engine GPU Acceleration (CUDA), then you are set up correctly. Nothing more to worry about. Same thing for After Effects.

      Finally, it doesn't matter which setting I use; CUDA or software - the rendering time is still the same.

      When you say "rendering," do you mean rendering effects previews or exporting out of Premiere Pro? If you are talking about exporting, it is a CPU based process so GPU acceleration is largely not used (exceptions listed here: http://forums.adobe.com/message/3377595)

      If you use CUDA accelerated effects, they should play in real time. I can place many effects on a clip and it will still play in real time.


      Hope that makes sense.

      Thanks,
      Kevin
