Intermittent Big Latency Spikes

I have been getting very large latency spikes since league start, and this has never happened before on a previous league start.

It happens with an inconsistent frequency but usually results in an unplayable experience because I'm either rubber banded everywhere (Predictive) or my character freezes for a few seconds (Lockstep).

I've tried every server in EU, tried a few others too and the issue is exactly the same everywhere, intermittent latency spikes. So for example the latency could be sitting comfortably at 15-18ms, then suddenly spikes to 500-1000 every few seconds.

I've reset my router and I'm not detecting packet loss from any tests I've run on websites and such, it seems to only occur for Path of Exile.

Would appreciate any help.

Thank you.

Tried a few more things to see if they would help.

-Factory resetted router
-Flushed DNS
-Used an AWS VPN
-Changed render engine to Vulkan (Was using DX12)
-Completely uninstalled the game and all other directories (Shader cache, etc.)

Still suffering from the same issue after reinstalling. It's a shame that it happened only for this league and never the ones before, I was most excited to play this one.

Will try again next weekend to see if there is a difference.

Hey, I've got the exact same problem. Looked like this:

Here is a clip with the connectivity menu open:

I tried the same things as OP.
I'm connected via Wifi and have a stream running on the second monitor most of the time, if that's somehow relevant.
