Definitely wouldn't recommend disabling idle it uses a lot of power and degrades the silicon so fast the cpu usually last around 2 years then the performance takes so huge hit you will need to buy a new system
i saw this happen to a ton of fortnite pro's because all the tweakers the first thing they do is disable idle
the smart way to use this would be to use process lasso performance mode and switch to your performance power plan with idle disabled when it detects the games running you can control what games this give you the best from both worlds
i actually do use this myself.
