Hi all,
Can anyone confirm they are seeing the same thing as me - openCL seems slower than CPU in Fusion 9?
Test - I took a DnxHR movie and connected it to a color corrector with an elliptical mask attached. So there was a circular color change in the middle of the frame.
With OpenCL OFF in the color corrector, playback was real time. With OpenCL on, playback dropped to 8FPS.
My system is 12 core CPU / 2 x NVidia Titan / Win 10 64bit / 64GB Ram / 600Mbytes-sec RAID.
Interestingly, GPU usage (as measured by GPU-Z) shows less than 4% usage with OpenCL on and around 6% usage with it off. Perhaps this is just due to more interface updates with the higher playback rate. I tried messing with the prefs>gpu settings, for example, specifically setting the target card, changing caching etc, but no difference.
Am I missing anything - any set up to enable the GPU?
Thanks
DC
