hi all
today i am trying to catch up with the newest pyglet API. It looks very
nice although a bit weird at the first moment. I am working on this
simple example where many instances of an object are rendered on random
locs on screen. On my Desktop this takes almost 80% CPU, i am pretty
sure i am doing something wrong because most of the CPU time is taken by
the render method, (If I comment render() out it drops to 4% CPU).
any suggestions? I am on Debian, on a PIV at 1.7 gz . Below i paste the
script i am working in.
thanks!
