However I heard that once you install a mod and then uninstall it, the save game and the script still have association with the old mod. My save is 7 months old, I installed and uninstalled many many mods. Also long ago I had DD installed. But the problems started a month ago.
P.s. I also tried 1.6 beta patch, still lagging.
