Lagging In Towns And Outposts

Hi i recently joined guild wars and though it was great, it was all runnning smoothly on the highest settings until i reached an outpost. It all went downhill from there, every outpost or town i visit i get this giant lagg when i enter. After about 5 minutes it will calm down and again run smoothly. I am pretty sure it is because this is where all the other online players are, but is this lagg due to a slow internet connection or poor graphics from my computer ? Please Help , Thanks

Best to find something else to do until A.Net sort things out on their end.
