How can I get show FPS to work?

[SnLnc]

For the FPS thing, open the console, type showfps, close the console, and hit F11.

I have gotten the console to work but the showfps command doesn't do anything.

Also when I load up with the console on I get a few error messages about graffiti or something I assume it is missing textures?

Anyone have any ideas please? images/icons/rolleyes.gif
