Okay so i recently started playing skyrim and i downloaded some mods, i played for about ten hours and im getting like 60 fps. Then i find this mod to remove khajiit tail and one to make the khajiit a little more buff, i installed the mods through nexus mod manager, when i launch the game after installing these mods i have 30-35 fps. I uninstall those 2 mods and now i still have 30 fps.

Any help would be great thanks.

What other mods are you using?
Does it still happen if you start a new game?
