I have my setting of this parameter at 2 as well and so far did not encounter this issue.
Does it occur in other projects ? Could it be due to one of the synth that was removed ?

Edit - I should have read your reply better before posting. If you are using a lot of 32 bit plugins, I believe you can get Bitbridge to assign specific "servers" to instances of particular plugins which consume more CPU cycles. I don't know what the correlation between Bitbridge servers and CPU core activity is though - but maybe worth looking at.
Sorry for the misread in your reply, Sharke.
