Prints the current FPS value (frames per second) to the console.
CS2D's FPS are limited to 60.
Note: Useful to check if a server runs at maximum speed (60 FPS)
Note: Dedicated servers do not render frames so the term "FPS" is a bit misleading. They are still limited to 50 main game loop iterations per second which is meant by "FPS" when using this command on a dedicated server. If the value drops below 60 often it means that the server hardware can't keep up with the action going on on the server.
