Greetings,
After playing this game in the last few weeks I found that players including myself have a sharing performance issue, which is the major lag which rending the game unplayable when the map starts to fill up with buildings units, and AI movements.
About the solution, I made a simple tutorial to demonstrate the solution:
Cheat Engine:

I hope it would able to help you if you have the same problem as I did, at least in a short period of time.
In the long run, I hope this can inspire the developer to improve the scripts in order to make this wonderful game become better.
Enjoy
Freddy
