Try loading esprit.flt three times in perfly.
perfly esprit.flt esprit.flt esprit.flt
I get this, with pipe stats.
Immediate 1.8, display lists 2.2
With my complex models, this is what I get as well, but worse.
The cow did get faster though.
So what's up with that? Are display lists inefficient on certain models?

well, on my linux box with geforce4, i can bring up perfly cow.obj
bring up pipe stats (the default stats use stippled lines, which are
slow), hit 'd', and watch the draw time drop from 2.0ms to 1.6ms.
on a higher polygon model i've got, it went from 109.8ms to 62.2ms.
looks faster to me.
