PrP CC2014 – GPU acceleration worsens performance
After updating to CC2014 we get worse performance when enabling CUDA or OpenGL on approved GTX680 card on MacPro with Mountain Lion. This is very apparant when playing Speedgrade looks applied through Direct Link. The clips can playback in real time at half quality when running software only ( improvement over previous CC ) but will totally stutter when enabling any kind of GPU acceleration in Premiere.

After some more testing it appears that the problem is isolated to Speedgrade Looks, where GPU acceleration WORSENS performance.
In all other instances of layering and effects handling, I get a substantial benefit from GPU acceleration with the GTX680.BTW I am impressed with the overall performance gains of PrP CC2014 – it is at least twice as fast as CC.

I have had a similar experience when it comes to the New Mac Pro with the D500 graphics cards and the Lumetri effect which is what Speedgrade applies to your videoclips when you roundtrip them back to Premiere. I have turned off GPU acceleration for the projects that I have used SG for. Its in the project settings dialog. You do have to render, but it will work without serious performance degradation. I hope that the new 10.9.4 update will fix this problem. Soon. Kevin Monahan is a great source of info, and I did meet him at NAB in 2013. He was able to help me with an issue relating to media encoder presets right then and there.

Yeah, I ran roughly a dozen Lumetris applied to an adjustment layer in Pr when I first got my nmp w/ d700s. Then I upgraded to 10.9.3 and everthing went to sh*te. I have GPU support disabled in Pr and AME until Apple gets their OpenCL act together hopefully with 10.9.4.

Is this a 10.9.3 issue or just a general issue? As in does it work in 10.9.2?
-
Yes,
10.9.3 was a bad deal, too bad apple won’t let you roll back without a time machine image…
Sometimes I feel like I am a beta tester for some software developers, which is kind of
distressing when you have deadlines….
Mr. Monahan if you are reading this, if you can give us an update as to where Adobe is with the Apple OpenCL issue so we can plan ahead, that would be great!Neal Bilbe
