Mac Pro 2014 - Davinci Resolve - 4K Video - Playback Stutter

Hello,

I Just bought a Blackmagic 4K camera with a Mac Pro ( model 2014 ) 6 Core/64GB Memory/FirePro D500/ 1TB PCie Flash drive. So I though color correction would we smooth, with this configuration.
But it is a disappointment even my iMac 27 inch ( model late 2013 ) i7 3.5 GHz / 32GB / GeForce GTX 780M 4GB is doing a better job.

If I open the 4K footage in Davinci the video playback is stuttering to my disappointment. When I mute the audio in the timeline it is a bit better.

Are you guys having this same problem with this configuration ? and is there a solution for it ?
( or must I install extra software ?? like CUDA for NVIDIA but then for Geforce )

My Video GPU Settings : use Display GPU for Compute and GPU Processing mode OpenGL
Actually I tried every combination but with no luck - OSX version 10.9.3

I hope somebody can help me, because I want trow my Mac Pro out of the window

Thanks,

Ashvin.

There is a known issue with Maverick 10.9.3 and OpenCL applications, like resolve. Not sure if specific to the D700 machines, but read here:

Otherwise, I would ask what debayer quality are you using? In the playback tab of the preferences...perhaps change it to Optimize for playback.

Hi Sean,

Thanx for your reply.

I'am newbee in Davince but I cannot find the playback tab in preference ?
See Attachment.

Or I'am searching in the wrong place ?

Hi, at this time, you need to install 10.9.2 OS.

Hi Peter,

The problem is that my Mac Pro is only 1 week old and there is no old version installed, so i cannot rollback to 10.9.2. But I called Apple, the say that OSX 10.9.4 will release soon, and that the now about the OpenGL problems. I Hope this update will solve it.

Thanks for your reply,

Greetz,
