c# - Incrase framerate in XNA

I'm trying to increase the frame rate of my game from 60FPS to 100 FPS because of reasons. But i can't seem to get it higher than 60 frames. This is the count I'm using. I can slow down the frame rate by setting TargetElapsedTime = new TimeSpan(0, 0, 0, 0, 16);

to a higher value, but settings it lower won't increase the frame rate, according to the counter. Anyone have any idea what's going on?

Answer

I found I had to do the following to set the FPS limit free. In your Game class, do the following:

graphics = new GraphicsDeviceManager(this);  // I have this stored as a member variable
graphics.SynchronizeWithVerticalRetrace = false;
IsFixedTimeStep = false;

Note that an unlimited FPS can cause unpredictability in physic engines, and network games. A full discussion of fixed vs variable timesteps can be found here: When should I use a fixed or variable time step?
