I am using Beta 1.2 Performer and I'm trying to get some statistics
output every couple of seconds. I basically want:

(1) Number of triangles
(2) Framerate
(3) CPU load

in samples of 2 seconds. I have been working to get this working for a
very long time, and I have run into wall after wall.

I can poll for the number of triangles as done in pguide/libpf/progs/stats.c
but this only works when I have the gfx statistics being printed.

I then tried to enable all of the StatsClasses myself (just to get the number
of triangles). So I looked in perfly/gui.c and got the stat_values[]
for the "Gfx" and tried to pfStatsClass(stats,PFFSTATS_ENPFTIMES|PFSTATS_ENGFX|
PFFSTATS_ENDB|PFFSTATS_ENCULL|PFSTATSHW_ENCPU,PFSTATS_ON); but that didn't
seem to do the trick. I still couldn't get the number of triangles
without turning on the Gfx statistics print feature. (Much less anything else).

I haven't been able to pfQueryStats on anything except the
PFQSTATS_GFX_GEOM_TRIS and as said, they only come in when I go to Gfx
stats drawing from the GUI.

So how can I get the 3 above statistics on a period of 2 seconds? (As
in how do I modify Perfly to let me do this?)

Thanks,
