So I've been playing Skyrim: Special Edition on Steam for a while, and I have not downloaded any mods. I log off the game after an ancient dragon fight. When I get back on a couple hours later, I have probably 1 frame a second. This has never been a problem before, I've always had a normal, good framerate.
Even on the "Main Menu", there is an incredible amount of lag. However, when I pause (esc), it goes back to normal. I have turned all my graphics, sounds, everything. The lag follows me all over the map, so it's not the area. What's really weird to me is the fact that when I pause, the game runs smoothyl, but it's still incredibly laggy on the main menu.
edit: The skyrim launcher tried to read my hardware and set my setting based off of that, but failed. Just as it did the first time. It usually doesn't ask for this, it only ever did it the first time I played
Fixed: I deleted both Skyrim.ini and Skyrimpref.ini at the same time.
