If anyone doesn't know already, and wants to use FPS counter but doens't want the performance impact of FRAPS or not-working third party counters, there is a console command for it.
PerfOverlay.DrawFPS 1
You have to type every time you start up and exit the game and the counter refresh is pretty slow, but it has no impact on performance.
