When I add this mod and play with my friends on dedicated server we have lower fps than we should, without this mod we all have 60 fps but when adding it it droppes. I recently upgraded my cpu but before I had like between 20 and 30 fps on average which dropped even more during various boss fights. We had to stop playing when we got to the point with Infernum Cryogen, spawning that boss literally kills FPS when Boss Checklist is enabled, without it - again - we all have stable 60 fps.
