Also in regards to your query, I thought of something else that might help. For some of these types of renpy games the load times of the game were completely different if I was playing the 32 bit version or the 64 bit version. it wasn't always straight laced with 1 being better than the other though... Sometimes the 64 bit version would run smoother, and sometimes it was the opposite. You could try this and see. You also might even be able to manually move your save files over to the other one without losing them(?) to experiment with this.
