Better graphics?

[GREEKLEADER]

Don't mind the games just Rounded,filled, Circular
Are these for graphics? Or maybe for better performance or smoother gaming?
Do answer,I need to know if I should put them in optimisation for the battery or keep them like that

@GREEKLEADER No, it's not tied to graphics or in-game performance. To the best of my knowledge, it limits background activity of apps that have it turned on.
