Casting Black Hole on Void enemies instantly caused enough CPU load to seriously lag my game for a few seconds and force my CPU fan into overdrive to keep up.
I have a FX 8320 (just barely the recommended I know but it handles the rest of the game just fine, solid 60 usually with vsync on), stable + cool OC to 4.2ghz. During the performance spike temps reached 51.3c (which isn’t high, until you realize my CPU fan went from the ~4000 rpm it normally sits at during gameplay to 6400 rpm in order to keep it managed).
