Far Cry - FPS?

I am playing the demo of Far Cry (Right Now). Here is a simple question for Ya. How to you get your FPS to post on the screen as you play?

Thanks

I always screw up the proper slash, so here it goes:

In the game, press the tilde key ~
type "\r_displayinfo 1" without quotes and press enter
press the tilde key again

Don't expect much if you're running at high (or better) settings

I am not expecting much, but the games runs smooth enough for me at high quality setting. I just want to see were I am at.

Thank Ya much.

That's cool, just thought I'd mention it I pull an average of about 40-50fps with everything on Very High or Ultra High (water) when playing at 1024x768 no AA no AF. If I bump up one resolution notch, my average framerate starts getting a little stuttery...
