seems to improve the late game performance for me. cheers.
core I7 7700hq

the only way that would benefit your game is your cpu is power or heat throttling. if it werent, it would literally make no sense for you to gain performance while reducing clock speed.
maybe try undervolting, doing repaste and clean vents/fan would help and without needing to turning off those performance features.
