I’m having lags/disconnects too, mostly in SPvP and PVE. SPvP is unplayable for me atm. WvW works fine though. Server is Drakkar Lake, I’m playing from Germany, ISP is Telekom.
Also most of my Lags seem to happen only on the receiving end; last night we were doing some explore-modes and I got serious lags, until the point where everything was standing still for me.
However, I was told that I wasn’t lagging for the others. So i tested that and I could actually play blindly for maybe 1 min until the disconnect.
The first time I got these lags I though that the problem is caused on my end, so I checked the most obvious things like firewall/router settings etc., but everything seems to be fine.
I pretty much didn’t change anything on my system since bwe 2-3, where I had no such problems.
