Graphical lag

[Neltharain]

-Platform : PC
-Once in a long while (not happen everyday)
-Wireless (which have better result in speed test than wired as suggest in above)
-Discord (I have two screen which my TV), Google Chrome, Mudlet (Have tried closing all three while running the game, and it still happen).
Also Kaspersky as anti virus in background (already bypass firewall for FFXIV)
CC cleaner in the background
Navidia setting in the background
-Frequency at which the lag happen? 5-10 minute into the game, restarting the game help but it still happen when 5-10 minute in
and yes I connect EU but I also have USA server character which also have the same lag
Like I said when I was in thailand I have notice there's a little lag from the internet(On both EU and US) but not a lag like I'm experiencing right now (On both EU and US)
If distance is the problem like you said shouldn't I get better connection in US server since I'm closer to that side now? why does the issue persist on both EU and US?

Also I used wired at first but it give me lag which start the whole contacting my ISP to fix my internet speed and Square Enix in the first place and after several speed test both wired and wireless (of multiple cable and multiple wireless equipment) I'm now using the one that get me the highest result by consider both download and upload as state in above comment

I also notice that it as FFXIV getting lag it also lag my other program out like discord when I switch screen to my second screen.
I was advice to try to don't load start up program which I go to System Configuration and uncheck box that say 'Load startup items' in Selective start up off and apply it then try restart
But when computer restart it revert back to old setting and load my start up as usual (Steam, Kaspersky) which I have no clue why (have try multiple time using either apply or okay but after restart it revert back to normal startup or selective with checkbox on Load startup items still on.
