Don't know of any new updates that would caused it. It start think last week for Heaven on High. Last update my pc need was about 3 weeks ago and have firewall turned off and have ffxiv set to run through it. Have no security turned on and have no programs that use internet running when playing ffxiv. Use a cat6 cable. When start getting the lag its always close to boss fight in Heaven on High. When not in it have no lag problems at all only time do is when wind is blowing really strong but other day there was none when happened. I'm not sure but always seems to happen around same time each day. Around 6pm to 9pm pst when have lag spikes receiving shows on game jumps from 30 and below to over 16000.
