I have no idea whether you're still working on this or not, but I'll add this anyway. I'm not exactly sure how complicated this would be to do, considering I don't know how to code games and it could require revamping to code as a whole or something... but is there anyway to run the game with more cores than it's already running on? Because the game extremely laggy but it's only using 20% of my cpu and I want to run some large simulations!
