I am making a python game with pygame on my home computer for school running with python 3.6.3 and pygame 1.9.3. When working on my game I also worked at school where it was working correctly just slower as expected but when I started to load images it randomly choose the images and didn't load the correct ones on school computer not home one (I think this might be due to change in arrays and loading them). I soon found I was running python 3.5.3 at school and then when updating it the python and pygame, The game ran extremely slow and was unplayable. The images loaded correctly but the change in speed was extreme.
Summary:
Pygame at home working great pygame 1.9.3 python 3.6.3. Working fine at school until loading images python 3.5.3. Updating school corrected it but is now running unbearably slow.
I would love a fix for this problem either working for other python version or running at a variable speed for school computers. If there is any optimisation that could be easily implemented that would be very useful as well as I am not sure how to load images effectively
