    this.Window.AllowUserResizing = true;
    this.Window.ClientSizeChanged += HeyCallMeWhenTheUserResizesTheWindow;
}
public void HeyCallMeWhenTheUserResizesTheWindow(object sender, EventArgs e)
{
    //graphics.ApplyChanges();
    /* we are here when the windows being resized */
    uiInput.SetWindowSizeRequiredForMouseLook(GraphicsDevice);

The following code will tell MG to sync on every second V-sync.

public Game1()
{
            graphics = new GraphicsDeviceManager(this);
            
            graphics.PreparingDeviceSettings += (sender, e) => 
            {
                e.GraphicsDeviceInformation.PresentationParameters.PresentationInterval = PresentInterval.Two;
            };
}

Thanks, that works. I’m converting an old xna game to monogame. For some reason my game runs faster in xna then monogame. Is this normal? That’s why I’m trying to lock to 30 fps.

What initialization code are you using? Are you running at a fixed time step? With vsync?

TargetElapsedTime = TimeSpan.FromSeconds(1d / 30d);

This is really the only line you need. Fixed time step is the default
