Addons reduce FPS rate?

Does having alot of addons and screenshots and maps cause your fps to go down, even if your not using them.

Because I downloaded LS and SBMP and it seems that my fps is lower.


and if it really does then is there a way to counter this, for example a mod that activates and deactives mods.

Yes. Most addons always run some stuff on the background.

Well ok thanks, removes the addons folder
