A week ago my game started stuttering really badly whenever I play, and I have no idea what could be causing it or how to fix it. It happens on every map no matter how many players there are, sometimes it's fine when I log on and it just gets worse and worse until the game is unplayable. I haven't changed any settings on my pc or in game, and gw2 is the only game that's doing this, my other games run fine.
