Need GPU performance increase through software

I need something software related to increase gaming performance!
anything like a game mode or GPU Turbo from HUAWEI would be amazing!

A game Booster from samsung that closes every app and focus on gaming only and also clear all the ram!

a weird thing about my SAMSUNG M20 is that i have 800mb free ram out of 3GB after even clearing my memory it's around 900

THAT'S ALL !! I HOPE SAMSUNG DOSE SOMETHING ABOUT THIS.
