It takes 100% cpu at all times:
ingame
ingame with battle running
ingame with battle running and many monsters to kill
ingame with battle running and many monstres to kill and heavy spell effects
ingame paused
gamewindow has no focus but is visible
gamewindow has no focus but is visible while other program has focus and fullscreen (my terminal is semi transparent so i can see the game, it is paused but updates the green moving line around the sneak icon (with 60 fps))
