i've only 2GB on the laptop im using at the mo but i make sure no other programs are running when im playing, except for norton. the minimum game specs require 1GB so surely 2GB should be enough
i've just had the same thing happen to me and im only 3 games into the first season. i've never had this problem before on any of the previous games. the only thing i can think may of caused it is the huge logo megapack i put on (2gb worth) but i dont know if that affects RAM.
