Extreme lag spikes in Eureka

Greetings. I've been getting extreme lag spikes in Eureka these past few days, to the point where I can't even tell if it's FPS drops or latency issues, although I have seen the "disconnected" icon next to my character's name whenever it happens. As far as I can tell, this only happens in Eureka, mostly during NM fights. There weren't any issues during my first few days in Eureka and this issue only started to happen 2 or 3 days ago.

I've tried turning down graphic settings and effects, but nothing seems to work. Anybody here encountered such an issue and managed to solve it? I'd appreciate any help. Thanks.

My PC specs if it matters:

AMD Ryzen 5 1600 Six-Core Processor 3.20GHz
NVidia GeForce GTX 1060 6GB
16.0 GB Ram
(Also running FFXIV in DX9 mode)

No, but like I've stated, I see the "disconnected" icon when the spikes occur.

2 to 3 days ago, as stated.

Just Steam, and sometimes Discord.

Only during NM fights in Eureka.

Turning down my graphics setting, and limiting spell/skill effects to just me, to no avail, which leads me to believe it might be latency issues.

Hello Raisek. Thank you for posting on the Final Fantasy XIV Technical Support Forums

The issue you are describing is most associated with interference with the game data. Most of the time, it results from certain security/privacy changes on Internet Explorer. Other times it occurs when an application that is running in the background is causing interference, such as Anti-virus software, firewalls, media players, web browsers, etc.

Please make sure all background applications (including anti-virus programs such as Norton, Kaspersky, Windows Defender, etc.) have been disabled and/or closed to minimize game interference.

Ensure that the latest version of Internet Explorer is installed on your PC (even if you don't use Internet Explorer), please do not use Edge as that is a different internet platform. Once Internet Explorer is up-to-date, please open the IE browser, open the "Tools", go to "Internet Options" and adjust the following settings:
Under the "General" tab, please delete ALL browser history.
Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
Under the "Privacy" tab, please move the slider to the lowest possible settings or to "Allow All Cookies"
Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED.
[SSL 3.0 should be UNCHECKED]
Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
Right-Click on the FFXIV launcher icon and select "Properties"
Go to the "Compatibility" tab, and change the compatibility mode to "Windows 7"
Hit "Apply", then "OK" to save the changes.
Please RESTART your PC now.


Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"

If the suggestions provided above do not resolve the issue, then there is a communication error.
Check the following Port Ranges on your router/modem to ensure that the following Port Ranges have been opened/forwarded/triggered:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

Hope to be of assistance!
