"dynamic plugin processing" Issues PT 11.2.1

[musicmixer04]

Just watched the video about dynamic plugin processing, and figured that it dont work the same at all in my system.

I have a clean install of pro tools 11.2.1 on my macbook pro late 2013 retina. 10.9.4

Running HD Native with Avid I/O 16*16

Im constantly having issues with cpu overload with few plugins, described in many treads on this board

Here is what I discovered compared to the avid video:

In my system, the 4th core is very high in cpu usage while the other cores nearly have any cpu usage at all. It dont look like the dynamic plugin processing described in the avid video work at all.

Dont know what to do to have the cores take equal cpu load. any preferences in PT I should check out?

Anyone have same issue?

thanks
