Having ASUS G76 and when try to run game in beta 5 was really laggy, specially in small towns. In beta 6 lag was reduced, but not sure unless they improving game engine with every beta. I am sure my laptop can pull far more then this games settings. It's i7 core with 6gb ram and 1gb 5870 radeon. From in game looks the game shouldnt be asking so much resources from what it looks like.
