That is telling.
I have done a few more tweaks to prevent gaming impacting icmp and dns too much. There may be some impact to P2P, which I will try and reduce.
I think we will have to test LOL at the office tomorrow and do packet captures, debugging etc. to see what is happening with the latency shown in this game, whether it is accurate, if so why it is so high etc.
I don't think it is just LOL (although I haven't tried other games),but others have complained about high latency in diablo 3 and dota 2 as well on this thread.This problem started for me on tuesday afternoon to be precise,played a game around 2pm and then from around 3-4pm it started and never improved since
