Indeed, good answer.

Also, are you using fast rendering techniques?

• Using 8 bit RLE encoded surfaces for the low colour depth images
• avoiding per pixel alpha surfaces.
• using convert() appropriately (except not on those low colour surfaces).
• using fill() to fill in colours instead of blit.
• using LayeredDirty sprite group, and DirtySprite sprites to do dirty rectangle updates.
• updating parts of the screen at the lowest refresh rate they need.  eg, displaying fps, may only need be done once every 10 frames.
• profiled your game ( to see which parts are slow.) http://pygame.org/wiki/Profiling
  

SDL 1.3 is faster with opengl/direct3d surfaces.  But it's _still not finished.
