Settings to fix Lag?
Dropping everything to Low doesn’t fix it, that only affects your FPS, not skill lag. People have tried every available setting in the game in an attempt to fix skill lag. The best you can do is check your ping, make sure your internet connection is solid, that you have sufficient bandwidth/speed, and maybe try a Network Interface Card like a KillerNIC or something. I’ve actually done all of these things, however, and I can say that it does seem to reduce the number of times that I get lag in comparison to other people on my server (who are in Teamspeak, at least), it does not make lag go away 100%. The prevalent theory is that the remaining lag, which is experienced by every player in the game at one point of another, is on Anet’s end somewhere.
