I have really high latency on this beta (minimum 500 ms and can rise up to 1500+ ms, the record being a bit more than 2000 ms), the game is unplayable for me. I didn’t had this problem with the previous beta week-end.
I’m logged in Europe in battle net which is the correct region for me. It’s not my internet connection i’ve checked and I’ve followed this article for help Blizzard Support - Diablo IV Connection Issues but that doesn’t change a thing. Also I don’t have this problem with d3.
The only explanation I can think of is that somehow I’m not in the correct network according to my location when logging in D4.
