[pygame] speed problem: max 6 fps
[this email doesn't seem to have made it the first time...?]
Hi,
I have written a small pygame game which won't run at more than 6 fps.
Approx. 55 Sprites live in a Surface, sized 2500 by 3000.
The profiler tells me almost all time is in the main function.
What does this tell me about the bottleneck of my little game?
My game, consisting of 4 source files, has been attached, although
I don't think thats necesarry because my problem seems to be
more fundamental (maybe c.l.py is better for this question?).
The result of the profiler is:
