Adobe Premier Pro GPU Acceleration Not working

[nikolaizombie1]

Hello, I've been noticing that the gpu assisted rendering process in premier does not speed up even with the mercury playback engine GPU acceleration (CUDA).

I used as a benchmark a 1 minute clip of 30 fps avi gaming footage and rendered in H.264 at  10693 Kbps and i got these results:

CPU Only: 1 Minute And 43 Seconds

GPU Assisted: 1 Minute and 41 Seconds 

 

not much difference with a gtx 970 and 4790k is it, what is the problem?
