Premiere Pro CS6: Add GPU Support

Posted on by Larry

I discovered a cool workaround that can speed up Adobe Premiere running on a Mac.

Adobe Premiere Pro CS6 takes full advantage of your graphics card. However, while there is extensive graphics card support from Premiere on PCs, it is very limited on the Mac. Specifically, Adobe has only announced support for the graphics cards in MacBook Pros.

Which doesn’t do me any good, because my editing system of choice is one of the new iMacs.

NOTE: I fully expect Adobe to add support for the new iMacs in a future dot release, but, for now, the iMac graphics card is not supported.

However, there is a cool workaround you can add to your iMac to make Premiere Pro think your graphics card is qualified. This requires a minimum of 768 MB of VRAM and, if you don’t like the results, you can easily revert your system.)


This changes a text file to make Premiere Pro think it supports your graphics card. This means Premiere will use the GPU for tasks like rendering, transcoding, and exporting; thus speeding up your system. In other words, this unlocks the potential for a huge performance boost.

NOTE: This won’t work on all Macs, and won’t work if you have less than 512 MB of VRAM. If experimenting with editing system files makes you nervous, don’t do this.

For the original post, visit here. But there is a MUCH simpler way to do this.


We are going to change the contents of the text file Premiere uses to determine which graphics cards are supported.

Go to the Apple logo and select About This Mac

Click More Info.

On the list at the left, click Graphics/Displays

Either copy or write down the Chipset Model. In this example, it’s “ATI Readeon HD 4870” Capitalization, spelling and spaces are all very important. (Your graphics card will almost certainly be different.)

Open your application folder and find the Abobe Premiere Pro CS6 folder. Open the folder.

Right-click on the Premiere Pro CS6 application and select Show Package Contents.

NOTE: Many Mac applications are actually collections of many different elements, all of which are normally hidden from view. Opening the package contents displays them.

Open the Contents folder and select the cuda_supported_cards.txt file.

Select File > Duplicate. This is VERY IMPORTANT, otherwise you won’t have an original file to revert to in the event something goes wrong.

Once you have a duplicate file, double-click the original text file. This opens the text file in Text Edit.

At the bottom of the list, copy or type the name of your graphics card, then Save the file.


At this point, close everything.

Start Premiere Pro CS6. If there is no problem, it will read the file and work faster because Premiere is now using your graphics card.

If there IS a problem, immediately quit Premiere, go back and delete the cuda_supported_cards.txt file you modified and rename the backup file you created to cuda_supported_cards.txt

IMPORTANT NOTE: THIS IS A HACK. While making this change should not harm your computer in any way, it runs the risk of making Premiere Pro inoperable. So, always make a backup of your original cuda file so you can revert to the original if necessary.

Let me know if this improves the speed of your system.

    Just tried this on my 5K iMac. I ran the system report and got:
    ATI Radeon R9 M290X as the graphic card. When I put this on the end of the openCL text file it still did not work. I poked around and found the GPU sniffer program in the directory. If you open contents on that then you can run the GPU sniffer terminal program. It will open a text window that shows the actual name that the GPU sniffer program pulls off the video card. For my machine it came up with:
    ATI Radeon R9 M290X Compute Engine
    When I added that exact text to the openCL txt file I then got GPU in the Project Settings. 🙂

    Haven’t tried a render yet but it seems to be running fine.

    Good times.

    I just tried Brad’s method on my Late 2015 iMac 5k with “ATI Radeon R9 M395X Compute Engine” being the text string revealed by the GPUSniffer Terminal program. (Premiere CS6.) It appears to have worked: Now “Mercury Playback Engine GPU Acceleration (Open CL)” shows up as a rendering choice. I haven’t done any work with it yet so I can’t comment on any speedup…

    Thanks for this 3+ year old thread!
