Graphical lag

[Neltharain]

I'm having a lag issue that I believe came from graphic or performance issue rather than the internet issue. I have submit ticket and already got help from Square Enix via email and after following their guideline which help fix the lag issue that happen right after I login. But now I am having a lag issue after 5-10 minute interval into the game and keep persisting in every zone I went to. Restarting the game does help at first but after 5-10 minute it came back again.
Already tried lower the graphic in game to lowest possible from the support I got via email, fixed the problem with laptop using lower graphic chip instead of the graphic card for high performance I got.

The support email advise me to post new thread in the forum here and provide information as seen below to get further help

I have try using my laptop built in wireless receptor and LAN Cable CAT6
LAN CABLE CAT6 would raise my Download to 400 mbps but limit my upload to 1 mbps
Which probably due to some of my program on my Laptop (tried do speed test on safe mode which seem to fixed the issue that limiting my upload speed, but I do usually run computer on safe mode and when I lived in Thailand with speed test of 30 mbps download and 30 Mbps upload, I still have less lag than this)
