Guild Wars 2

I never experienced lag in this game until Rising Flames released. Beginning on that day, i’ve experienced a lot of lag. Usually, it’s a lag of about 30 seconds +/-. More infrequently, it’s 1-5 seconds long. At first, i only noticed it in Ember Bay, but after a few days, i started getting it throughout the whole world. If i’m with my guild when it happens, i’ll ask them if any of them have it. Some have said they’ve had the short lags as well, but no one else has mentioned the long lags.

You mean like FPS drops for several / many seconds?
Did you change something else on your PC, approx. at the same time of the Rising Flames release? It feels a little like an external issue if it can appear anywhere.
