Late response is late:
We tried the beta patch, but were still getting lag issues- It's improved greatly since the first post was made but it's apparently still pretty unplayable
Honestly given the amount by which the OP usually lags in other games- it's probably safe to say that at this point it's now just his connection being unable to handle the way the game handles large numbers of loaded systems and save files. Amishland internet tends to not be the best.
Thanks for the help though~
