Hi

was it the pygame.clock.tick() the method that used a busy loop to get 
the right timing? The online documentation seems to have changed and 
says not so. If the tick() method uses a busy loop then your nearly 100% 
cpu usage would be esxplained...

For the movement I would recomend time based movement because then they 
move on every machine at same speed :-).
For a really smooth movement I think you would have to use motion blur, 
but I do not know how to do that.
