Odd lag issue?

Ever since maintenance needed I have had an odd lag issue. My net runs very smoothly and all tests check out, but ingame I start lagging terribly...only when people are around. I can stand in Summerfor shooting targets with no lag then go to a city and get 0/0 followed by 9002 until I can crawl my way out.

Everything else internet is working without a hitch. has anyone experienced similar or know what the cause may be?

Yea I've been having the same issuing recently as well thought it was my computer so I did a whole OS reinstall and tried a different PC with no luck I'm hoping with today's maintenance the issue will be fixed.

Are you two playing in the Asia-Pacific region outside of Japan by any chance? Which country?
