This is not that simple. Marcus told me that for server this is  
important since it can suck all cpu.

I believe we are in agreement, just using different words:
- Server mode: Gives 50ms between redraws for non-GUI activity.
- Normal mode: Gives (20ms - Time spent in last redraw) for non-GUI activity.
- "higher"Performace: Gives (1ms - Time spent in last redraw) for non-GUI activity.

If there's no new damage rects, no redrawing happens in updateCycle.
For say, a server app with f.ex. a monitoring GUI which sends out dmg rects once one of it's models values that are displayed in the GUI changes, normal can be painful, and downright nasty with higherPerformance enabled when it comes to time left to do actual application stuff... (Especially if GUI contains complex elements, damage rects are somewhat off, + a plethora of other things that are, at the moment, quite likely).

So server mode setting is a must-have, higherPerformance not much so.
