I keep all CC to a minimum.
I have no mods in my game, I genuinely have no use for them with TS4 which is great.
Plus as others have stated, I can't be bothered to update mods every patch.
My game runs extremely smoothly and any CC I download I check it immediately to see if I like it in game.
I also trim my mods folder of any CC I'm not using and I don't use a lot.
Just some tops, bottoms and accessories..also some skins, but only little for each category.
I also stir clear of furniture CC.
This is the first Sims game where my mods folder is relatively very small lol, I like it.
