Multiple projects at once

Hi :slight_smile:

During mixing, we sometimes work several parts in each individual projects.
For example, drum part for one, melodic for another, vocal for the other.
I wonder that, if I open more than two projects at once (one mastering project,
another for detailed part), how does the cpu burden goes?
Is it the same amount with just the sum of tracks of both projects?
Or a lot more than that?
Is there anyone who work with several projects opened contemporarily?


It’s almost the same, like to open only one of the project. Only one project is active, this one eats the CPU.
