A Little Hacking To Get Your GPU To Work
The list of supported GPU’s is short – just 2. However its pretty easy to get your own GPU to work provided it meets the major requirement ( at least for CUDA ) of at least 768mb of VRAM. The GPU in my 2010 iMac is a 5750 with 1G of VRAM. A slightly older GPU, but enough VRAM to give it a go. Here is how I did it.
1. Location the actual Premiere Pro application
2. right click on the Prem Pro icon and in the contextual menu select “Open Package Contents”
3. Open up the Contents folder
4. Right click on the file named opencl_supported_cards.txt and do Get Info on the file
5. At the bottom of the Get Info window click the lock icon, enter your admin password when asked
6. If Sharing and Permissions isn’t spun down, do so
7. Change to Read & Write
8. Close the Get Info window
9. Now open the opencl_supported_cards.txt file into TextEdit. You’ll see 2 cards list there.
10. Go to the OS X’s top left apple button menu and select About This Mac
11. In About This Mac hit the More Info Button.
12. On the first screen ( Overview ) you’ll see your GPU model. Drag the mouse cursor over the text so it selects, then hit Command C ( copy )
13. Back to text edit, go to the end of the last line. Hit enter, then paste the name of the GPU in.
14. Hit Save and then close the file
15. Start Up Prem Pro and enjoy hardware MPE on your ATI / AMD GPU
