I have only used the 'fps' feature on Window and OSX.  Maybe this is not implemented on Linux?

I just tried this but also with 'profile 1' I cannot get the framerate
(is still zero), I only get lots of "GEM: time: 0,102756" messages in
the console.

I try to read the framerate with
float framerate = GemMan::fps;

Thanks,
