CUDA or OpenGL on new iMac?
Hi Guys,
Coming from MacPro/FCP7/Kona setup, only done 3 or 4 projects in Premiere so far, so please bare with me…
My displays have been wigging out a lot. If I restart Premiere it fixes itself for a little bit, but then comes back. Working with AVC-I 100 stuff right now, but I’ve had a little of this on the previous projects.
I have a new iMac (see signature) and did not see any updated drivers on nVidia’s websites. I did see this CUDA for Mac thing, so I downloaded and installed the latest version. What should I be choosing for Mercury settings? CUDA or OpenGL? Is there something else I’m missing to get the most out of this setup?
I also added a 23″ Cinema Display using a Thunderbolt to DVI adapter plugged into the Pegasus. Is that unwise or should this all be running smoothly?
As always, thanks for all help! COW rocks.

I don’t know much about any Thunderbolt issues that might arise from your configuration, but while your system RAM should be good, your display card doesn’t have enough RAM to run GPU accelerated (CUDA, not OpenGL on an NVIDIA card). You may be able to hack it and get Premiere Pro to try to use that card, but especially running a couple displays, I would think it would become problematic.
I believe 768 MB is the minimum spec for GPU acceleration for Mercury, but as with RAM, I’d recommend going above the minimum. I have a 2GB Quadro in my laptop.

Thanks for the response. I have these issues using OpenCL. Current version of CUDA for Mac does support the 650M without any hacks.

Well…you don’t have OpenCL problems with Premiere Pro and that card…GPU acceleration on NVIDIA cards is based on CUDA. The only cards that CS6 will use for OpenCL are two MacBook Pro AMD cards…
While you can load NVIDIA CUDA drivers for that card…it doesn’t have the minimum RAM requirement for PPro…I’m not sure how it would allow you to use CUDA GPU acceleration without at least changing the text file…

Current version of CUDA for mac is 5.0.45.
Release notes for 5.0.17 state that support for the GT 650M was added.
https://www.nvidia.com/object/macosx-cuda-5.0.17-driver.htmlBelieve it or not, the CUDA option seems to be running a little more smoother for me than the OpenCL option. And of course, the software only option turns my entire sequence red.
Thanks Again!

Anybody have news on the card in the new new iMacs (NVIDIA GeForce GTX 780M 4GB) being supported for hardward CUDA acceleration in Premiere?

Also, some customers may be aware that in the past there was a not-so-secret way of enabling non-supported GPUs by the ‘hacking’ or removal of a text file. This is no longer necessary in Premiere Pro CC. As long as you have a reasonably modern card with at least 1GB of VRAM, you will still be able to enable that card in the Project Settings dialog. A warning message will appear letting you know that your card has not been certified by Adobe, but once that dialog is clicked through you can use your GPU. The team does try to certify as many GPUs as possible, but we can’t test everything, so this is a way to let you decide if you’re happy using an untested configuration.
——————-
The NVIDIA GeForce GTX 780M 4GB may not be officially supported (tested by Adobe) it will still allow you to enable GPU acceleration.

Recently tested Premiere on the latest iMacs with NVIDIA GeForce GTX 780M 4GB GDDR5, and hardware acceleration was unavailable… Would love to see them officially activate this without need for hacks! 🙂

Premiere just added support for a bunch of new cards, including the NVIDIA GeForce GT 750M, which is the card in the smaller iMac. I’m a guessing the NVIDIA GeForce GTX 775M will be coming soon…

Even though the GeForce GTX 780M isn’t officially on the supported GPU list, you should be able to enable it. This is new to Premiere Pro CC 7.0 and newer versions. You will get a message saying “This card is not supported” but just click OK and your good to go.
If you don’t see CUDA acceleration as an option make sure you’ve installed the CUDA driver.
