Can you provide a save game wiht the slow performance?
i moved quite a lot from that save and like i mentioned i really don't think it is this mod's fault, i assume it is how i play (i never go for optimizing by any means) but if you still need my latest savegame (which i am having issue with another mod :D) feel free Klonan :)
like i said even without your mod i can only go up to 300ish ups :D and as i said i moved a lot since then, added a lot of extra modes, changed a lot of settings (added warehouses, merging chests, increased stacksizes etc which can be counted as anti-opmimization :P)
