In ppracer, go to Configuration -> Graphics -> Display FPS.
I mentioned ppracer as a bit of a sidenote, since not all applications
in Sid could handle Xorg's dri at first. Up until just recently,
glxgears/glxinfo would show I had dri enabled in Xorg, but applications
like ppracer would only show about 20fps (and cpu usage would go
through the roof).
If you prefer glxgears stats, though... I'm currently getting ~1400fps.
HTH,
