Get the ancient and still remarkable CoreMaximizer1.03.
16 years old and it is still optimizing CPU core balance speed.
It does not affect the "CPU Score" results, but you will have a way better experience.
I have an i7 13700k, and with CoreMaximizer1.03 on, it is way better; noticeable when you have a zillion of units on the field.
I hope it helps.
Cheers
