Anyone know the FrameBudget is?

I was poking around in the ServerConfig class and saw that there is an option for FrameBudget. Anyone know what this is used for and what it affects?

Code:

  [XmlAttribute("FrameBudget")]
  public float FrameBudget = 100f;

 

It seems to be the desired max server fps

 

No that is TargetFPS

 

oh, right, sorry, i've read a bit too fast.
It doesnt seems to affect anything yet, tried multiple values on several servers.
