Over the past few weeks the only thing I've changed on my end was putting in a better 3D card, which has in fact helped the game play much smoother when I don't have lag.
So, my question is thus: Do I need to report it somehow? If it's an error on Anets side, if that's possible, then they would need to know to track it down, wouldn't they?
Otherwise I'll just continue playing in 15 minute increments.
