EDIT: Taking back what I just wrote.... I think my issues were more due to the fact that I was testing with a ProRes clip.
I just loaded up on of the finished files in 1080p and added a default Magic Bullet look to it and there was no issues. 1/1 playback with 25 fps.
So yes, it does work, although Adobe will tell you it's not certified as they have no love for the 900 series.
Funny thing though, when in DaVinci Resolve 11 Lite, the same ProRes clip that gives me issues in Premiere runs flawlessly.... getting more than 25fps with 4 nodes of correction.
I hope Resolve 12 will be stellar, would be a good time to stick it to Premiere
EDIT EDIT: So I just found out that if I start up Quick Time Player Pro 7 before starting up Premiere Pro and allow qt32.exe to go through the firewall, the same ProRes clip plays without a hitch. How about that....
