Hrothgar

Quick question. I found myself playing this demo lately for hours on end. Only thing i dont like is that sometimes lag is a big factor in my death. My system is middle of the road and i have a DSL line so basically I was just wondering if just the demo is laggy or if the retail version also laggy? I think I read somewhere that this game did have some stability issues but that recent patches have made it more playable, i.e., less lag.
