Constant packet loss since patch 6.3

[KhevanFarstryder]

I'm from the Faerie server on the Aether DC.

Prior to patch 6.3, my connection has always been a solid 30ms to 40ms ping with no packet loss. Even during the height of the Endwalker release, once I was in my connection was completely solid.

Since patch 6.3, I'm getting constant and persistent packet loss. Everything on my screen will freeze for 3 to 5 seconds and then everything will happen all at once. This seems to happen every 20 to 30 seconds and is making it very difficult to play anything.

I've done a speed test on my internet and I'm getting 1GB down and 100MB up with no packet loss. Rebooted my modem/router and problem persists. Doesn't seem to be anything on my ISP's side as everything else runs perfectly fine. I checked my Task Manager while running Euphrosyne - CPU and RAM usage seems normal (averages 40% CPU and 2.5GB RAM usage) so it doesn't seem to be a hardware issue either. Rebooted my computer just to be sure and problem persists. Doesn't seem to be a problem of server congestion as even in the height on Endwalker release I never had this issue.

Was any of the network coding changed in 6.3? Is anyone else having this problem? Please help!

I play on Dynamis, Seraph and I'm also experiencing awful packet loss. I'll have to get a VPN if I want to play this game.

Also getting packet loss on Elemental.

Luckily, I have access to a broad amount of systems, hardware, networking equipment for work, as well as fallback connections for network uptime.

From 2 locations I have done the following tests, all bring up the same stutter and packetloss.

Tested 3 ISPs,
Telstra (Cable)
iiNet (Fiber)
Vodafone (5G)

3 Systems
Windows 11 x64 (Laptop, Clevo NH55HPQ) [Wi-Fi AC/AX]
Windows 10 x64 (Desktop, self built) [Ethernet]
Mac OS (Macbook pro 2016 w/ touchbar)

3 Routers
TP-Link Archer VR500v v1
TP-Link Archer VR1600
DLink DIR-2150

This is only since 6.3 and I assume due to the change in compression stateless VS stateful.

This is made more evident if you put your network under strain as packets become delayed or discarded, which then also seems to lead to memory leak within the client itself when you desync, using up to !!!100GB!!! of ram on my 128GB system (I do design, production, and audio on the side of programming and networking admin)

Clearly something was not tested here.

Edit to add: You're not alone on your lag issues, more than 100 people within my discord servers have complained of the same since 6.3, mostly from NA, but some from JP, EU, OCE.

Edit to add:

Static members now complaining of lag, eaten GCDs, missed positions etc in raid.
Locations: Australia (QLD), Singapore, Malaysia.

Another Echo of this on Cactuar. Haven't had issues for the last 5 years on the current ISP I have, and then SUDDENLY since 6.3 it's been rough, and multiple roommates who play in our house also are complaining of packet loss at this time.

Also experiencing this on Elemental-Tomberry and it has been a constant an issue since the 17th. Lag is unbearable with GCDs not registering, DC’ing, freezing, teleporting etc.

For me, it's been happening since 6.2. Every 2-5 minutes, I get a 6 seconds window wherein my GCDs don't want to go off unless I over-spam them. It often causes me to mess-up my combo which is especially bad on DRG, being the combos are 5-parters.

I'm sure it has something to do with DC travel which was also introduced in 6.2. Maybe it puts too much strain on servers? I hope it gets resolved soon..

Bump, this is still a massive issue. The lag is making the game unplayable. I truly hope after maintenance on Tuesday will fix the problem at this rate…

It’s Tuesday post-maintenance and I’m still having particularly bad lag in Euphrosyne. Lagged badly during the floor AOE bit from Halone, definitely messed up my rotation a couple of times. Felt like the execution of my GCDs was going slower than usual in general for a 90 raid.

[Booket]

Sad to hear it’s affecting you too. I also had issues during the 24 man as well. Similar experience with people teleporting, missed GCDs and seeing my character have the DC symbol.

I did some UWU with friends yesterday and it was fine so I thought it was better… but today in the 24 man was rough.
