Hello. everyone :) I've been doing some modding today and settled on https://next.nexusmods.com/skyrimspecialedition/collections/uoiso1 And I installed it and so on and absolutely ADORE like absolutely beautiful really stunning but a problem is it's running at 15 fps my Gpu is at 100% and Cpu at around 15-20 % and by my standards this is pretty much unplayable so I've come here to ask what I could do maybe some of you can give some suggestions or maybe a different more lightweight collection ❤ My Specs: AMD Ryzen 5 4600G GTX 1660 Super 16Gb Ram 1080p Thanks !
