I am trying to get my Radeon HD 7970 to work with Premiere Pro CS6. The official compatibility list states that I can use this card to accelerate the Mercury Playback Engine. After Effects and Photoshop CS6 both recognize the card but Premiere Pro will not. I have tried every fix there is out there, I have contacted the support department and they assured me that it should work with CS6 and with CC.
I tried a fresh install of my OS and a fresh install of CS6, then fully updated the software. I have also tried the same with the CC trial, which I'm told that CC is actually just CS6 so that was apparently a waste of time.
What do I need to do to get a supported card to actually work with Premiere Pro?
My OS is updated, I installed the latest drivers for my GPU and also tried a fresh install of CS6 and of CC... no luck whatsoever.
MPE setting stays greyed out no matter what I do.
