I've read about this phenomenon here: http://forums.nexusmods.com/index.php?/topic/626132-script-lag/

Anyway, it's happening to me...

At first I thought my sheer amount of mods was causing lag, but it was steadily increasing--along with my save game size.

So I used the tscr command to disable all scripts, and suddenly the game is all snappy and back to its original FPS. Clearly I have some sort of savegame lag. It only happens on one of my characters. The others don't have it.

I've read removing the scripts folder works for this, but I would like some experienced opinions on this issue.
