Hey guys, I'm new here and I was hoping someone would give me a light about this "bug" I have. My Skyrim plays fine everywhere both interiors and exteriors with 40-60 FPS BUT sometimes, almost like random, when I enter a interior cell (e.g. Ragged Flagon, Dawnstar Sanctuary etc) my FPS simply will drop to 25 FPS when I'm looking at certain specific locations.

I am sure it is not an overheating problem because sometimes it happens after only one minute of play, and other times it doesnt happen after hours of intense playing.

I have some mods installed (obviously lol) and I was thinking it was a mod "overload" problem, but after unninstalling every texture mod the problem won't go away.

I already tried a fresh install of Skyrim and of mods but it persists. I'm using a

Can someone help me please? If you don't have any idea about it lets talk and see if we can think about something.

Here's my mod list, I use LOOT to properly assign the load order.
