Adobe has not optimized their apps to make full use of the GPUs in the 2013 Mac Pro

Oct 28, 2015 6:55 AM in response to lllaassby tijmen22,Thanks! There are just a little to much issues with premiere now. Cursors is really buggy and lumetri color doesn't work like it's supposed to. Turning off mercury doesn't seem like a real solution. I just did the new update for el capitan, now my USB keyboard doesnt work directly in connection with macpro, Can only use it via an TB hub

Servers EnterpriseI cannot add anything regarding your keyboard issue, you could try speaking to an Apple Store genius about that.
With regards to Adobe and your Mac Pro I can provide some information. Adobe have historically and still do write their software to be optimised for using Nvidia's CUDA software. This allows off-loading processing to the Nvidia video cards. CUDA however is as mentioned Nvidia software and hence does not work on AMD video cards. As the new Mac Pro which you have has only AMD video cards and these cannot be swapped this means Adobe software is not optimised for your Mac Pro.
As a comparison Apple's Final Cut Pro X software is optimised to use OpenCL and OpenGL, these work on both AMD and Nvidia cards but Apple have again optimised it specifically for the two AMD cards fitted in your new Mac Pro.
As a result of the above currently it could well be the case that if you bought or had a 'classic' Mac Pro which allows you to swap the video card, you could fit an Nvidia GTX 980 card in it and Adobe Premier would probably be faster than the new supposedly faster Mac Pro you currently have.
For the future things might change for the better. As mentioned Nvidia and Adobe use CUDA which only works on Nvidia cards, and Apple used OpenCL and Open GL which works best on AMD cards although they do work on Nvidia as well. The future possible improvement is that Apple have with El Capitan added a new alternative software system called 'Metal'. This does similar functions as CUDA/OpenCL/OpenGL but is designed to work on all sorts of video cards including AMD and Nvidia and Intel. If/when Adobe re-write their software to use 'Metal' then it should be significantly faster even on AMD video cards and Adobe have already done some impressive demonstrations of the potential of this.
