it boost everything, it boost stars gained, it boost NP gain per hit and it also boost damage doesn't matter if it quick, arts or buster.

problem is most servant Buster gave you 0 NP and star per hit so performance up only boost their Damage, not everyone ofc those with multiple hit buster gain 1% to 2% NP per hit with Buster up.

To make it easy to understand each card type have default value of Star gen, and NP gain aside from damage, When you use atk up only damage value got extra modifier, with performance up NP gain and Star gen got additional modifier alongside with damage at the cost that it only affect spesific card type.
