I have always been under the impression that Premier Pro utilizes CUDA for graphic acceleration and that, if using consumer graphics, nVidia should be used for its CUDA capabilities. I also understood that whilst the "approved list" for cards for graphic acceleration is very limited basically to a few Fermi cards, Kepler based cards were suitable; it was just a case of "introducing" them so they were recognized by the software. Lately, I have been hearing that that is no longer the case and Open GL is used instead, opening up the suitability to AMD graphics cards. I have also heard that this is in the "process" of being changed. Confess I am confused. Could someone possibly point me in the right direction. Many thanks.

That is incorrect as far as Windows is concerned, PR uses DirectX and not Open GL. AE uses Open GL. What the future will bring in terms of Open CL support is written in the skies. Currently only certain nVidia cards with at least 896 MB VRAM can support hardware MPE. They are not limited to the supported range, as is shown here: MPE Charts
