title: Do global variables mean faster code?
body: <p>I read recently, in an <a href="http://www.gamedev.net/reference/articles/article537.asp" rel="noreferrer">article on game programming</a> written in 1996, that using global variables is faster than passing parameters. </p>
  
  <p>Was this ever true, and if so, is this still true today?</p>
