I play with my old pc with 1002 updated.
works fine for me. only after hours of playing, the game will lag a bit.

my experience is hv to fresh install the game then update the latest patch. otherwise the game will go wrong.

btw ...patch 1005 is out !!


my system:
Vista Ultimate
P4 3.0HT
2 GB ram
160 HDD
ATI X300se


thats it...
