Need help on determining what's the cause of script lag

I made a fresh install and started installing mods, i tried to balance performance and visuals and somehow i did it, usually hitting 30-40 fps in most areas 50-60 indoors, its pretty good considering my pc specs

But i noticed that dialogues doesnt advance immediately, when i enter mcm, its blank, and some mods dont function and given a few seconds, it goes back to normal. And when i go outdoors and enter combat, massive stutters happens and it just goes back to my usual frames

Idk if this is really script lag but if it is, i need help determining it.
