1) I remember out of view draws slowing my fps very little. As i zoomed out
so more was in view, my fps slowed quite a bit. Have you verified that off
screen draws are significantly impacting your performance?
2) you should profile your code.
python -m cProfile -s cumtime yourscipt.py > profile1.txt
Pipes the profiling information sorted by cumulative time into a plain text
file on linux.
