Fluid Playback possible?

[Anton]

Dear swarm.

Is it possible to Playback a DCP without framedrops with DCP-O-Matic?

I think about upgrading my ram (from 16 to 128), but I am not sure if is the only determining factor.

I am using a 6.1 MacPro
Processor
3,5 GHz 6-Core Intel Xeon E5

Graphics
AMD FirePro D500 3072 MB

Thanks in advance
Anton

Are you using the "OpenGL" video mode in preferences?

[Anton]

Hello Carl.

Thank you for your question.

In fact, I did not.
Now i do.
If I playback the DCP with quater resolution, it really does not lose frames.
If I playback the DCP with half resolution, it starts to lose frames.

Do you think more Ram would make it possible to Playback in full resolution with no dropouts?

I'm a bit surprised it doesn't work better. Did you re-start DCP-o-matic after changing the option?

Can you check the CPU load while playing a DCP?

The 6core E5 might be a bit too weak for this. Check both CPU load displays in activity monitor (utilities folder.

Is this a 2k or a 4k DCP? Framerate?

Adding RAM will not improve playback performance.

Is the DCP on a local/SSD drive, or on an external/USB or network drive?
