Significant increase in lag over the past few days. I have not changed any of my settings. RTT used to be around 50 with STDdev of 0. Now its RTT 200 or more and STDdev of 200 or more as well. What is happening? FFXIV is the game btw.
No perfect answer for this question because it’s very vary depending on which ISP you’re using or how is the international cable condition good.
