Lag Spikes/ Network problem

I have over 260 hours in PoE 2, but since yesterday (04/09/2025) the game has become unplayable. My latency jumps from 10ms to 200ms, sometimes even spiking up to 600ms.

Before this, I had zero issues, everything was smooth and stable, and my local internet is working perfectly (I tested it thoroughly).

Please, GGG, take a look at the São Paulo servers. I really want to enjoy the game again, but right now the connection makes it impossible.

I'm having this as well, did you try another server? It's happening to me on all servers.

lucky this just started happening to you, ive had 1k spikes since EA launch... still no fix in sight

I couldn’t test other servers because there aren’t any close to me, as I’m from Brazil. If you’re in the US or Europe, I’ve read that some players managed to fix the issue by switching servers.

After looking through several solutions that other players shared, here are the changes I recommend trying:

Steps to try:

1)Try other servers
If possible, connect to a different server region (US or Europe).
Some players reported this fixed their latency issues.

2)Increase NVIDIA Shader Cache Size
Open the NVIDIA Control Panel (search for it in the Windows Start Menu).
Go to the Manage 3D Settings tab.
Find Shader Cache Size and set it to 100 GB (or a smaller value if your C: drive has limited space).
Click Apply.

3)Disable IPv6 and force IPv4
Go to your Network Connections settings.
Uncheck Internet Protocol Version 6 (TCP/IPv6) and make sure IPv4 remains enabled.

4)Adjust PoE2 networking settings
Open the game and go to the Settings Menu.
Navigate to Game → Loot Filter and click the folder icon.
Locate and open the poe2_production_config.ini file (you can also search for it directly in the PoE2 folder).
Scroll down until you find [NETWORKING] (note: search doesn’t work inside the .ini file, so you’ll need to scroll manually).
Change networking_type=auto to networking_type=predictive.
Save the file, close it, and restart the client.
