Viewport performance plummets when probuilder window is active

Title says it all really. Viewport performance is like 144+ fps normally, then I open the probuilder window or select the tab so it’s active and the fps plummets down to 20-30fps or so.

This has always been the case even before Unity bought it. Very unlikely to ever get fixed considering how it all works under the hood.

Fair. It’s pretty annoying having to switch back and forth since moving around in the viewport is so laggy when the pro builder window is active. Ah well, never mind.
