Your English is great so no worries there
I would guess that the plugins you posted are a bit of CPU hogs and need a larger buffer size. Also I never ever look at those cpu meters as it doesn’t do anything for us unless there is a huge issue that make me think of a bad plugin.
Have you double checked ALL the plugins as if you have old versions and or a few bad demo plugins even if not used at all can cause havoc on the CPU.
I would drag all of them to the unused folder and then put them back a few at a time and test the session before adding the next batch.
Also make sure you trashed preferences and databases and let PT re-read all the plugins again AFTER you done the look thru all the plugins making sure they are all 100% updated and demos thrown away.
