So, I’m going to try something new. I’m not happy with the way it is rendering 100% but it should copy\/paste fine. Most probably have one by now but I thought I’d share my frames per second component outside of a tutorial on its own. It renders the FPS into the title bar of the window and the output log in Visual Studio. I recommend using the base constructor and adding it to the list of game components in the constructor using Components.Add(new FramesPerSecond(this))<\/span>.<\/p>\n

UPDATE:<\/b> I fixed the issues I had with code.<\/p>\n
