It is not on my in. My internet is great and all other games work outstanding. POE, Classic WOW I also play. It is something in how their servers are set up. Anyways today is Day 3 and it is still un playable. I did get a 97 ping which was the lowest official servers. It was still too laggy. You could login but there was rubber banding and lag in button responses so log out and tried for over hour to get a lower ping but it stayed between 110-160 unplayable. I have uninstalled and ask steam for a refund.
