[pygame] pyopengl sprite/particle performance

[flx <xf3l1x@xxxxxxxxx>]

Hi all

I've been fidling for some time with pygame on a tryout project [1],
it's a fast 2d action game.

After a while i switched the drawing code to pyopengl looking for a
litle performance boost, but i haven't got the expected results, i
have had to lower the global fps from 60 to 30 and even then, it lags
with 150-200 sprites on screen.

I know there must be something wrong with my code because  there are
more complicated things drawn with pyopengl.

This are the first lines of profiling output (switch to monospace font now ;) )

code referenced is on [1] or running > svn checkout
http://pyship.googlecode.com/svn/trunk/ pyship < recomended since the
tarbal is several days old and there are some particle and sprite
especific examples on the svn
