Is it dependent on PRINT_MODE? Please upload a save that reproduces the problem to http://dffd.bay12games.com/ [^] and post the link here.

No; the game lags excessively in STANDARD and 2D.

This save has a tree farm (bound to F3):

I can't reproduce the problem with that save, either paused or unpaused. If the issue is still occurring for you, are you using a graphics set?

I still can't reproduce this in the save you posted, but I can in the save from 0008966 (CPU usage in the initial viewport is twice the CPU usage when viewing the area from a few z-levels up).
