This is pretty bullshit. Nemesis in no way does anything to FSMP so idk where the fuck you are even getting that from. And that FSMP setting only applies to wigs, it only means when you have a base SMP hair (applied through racemenu) and equip a wig it will disable that base SMP hair on the head. Also mipmaps dont decrease performance, infact not having them decreases performance, so you are wrong once again. Mipmapping increases cache efficiency as full-size textures will not be needed as often, and the lower resolution mipmaps will fit more easily in the texture cache.
