has the ram usage been sorted out?

[Com]

Hi guys, i used to play just after the game was realeased and i only ever stopped playing because of the rediculous ram usage. Has it been sorted out? I was on 768mb ram and it even lagged with that.
Oh and by the way, id just liek to add that sony are greedy c**ts, i cant even post on their forums because im no longer a subscriber, its made me so angry that im tempted not to even re subscribe but if the ram has been sorted i may well join up again.
