At my wits end with these huge lag spikes (US East)

Playing on US East, direct ethernet from router to PC. Gigabit internet. No issues with other apps. I know its not my cable or anything as if I plug it into my xbox its getting over 900mbs down and 40 up. Have tried every speed test know to the internet, all seem fine.

Had no issues in prior leagues or the start of this one. Issues started about a month ago. I average around 12ms ping, and randomly once ever 10-15 mins it spikes up to like 20000.

I have tried resetting all network devices and hardware. Updated network drivers, reinstalled drivers, enabled QOS on my router and got an 'A' on bufferbloat test. Tried limiting bandwidth on router, everything. Tried with VPN, with no VPN, tried connected to a bunch of different POE server gateways.

Nothing seems to fix it. It's just PoE. Its absolutely infuriating. I love the game and I want to play it but it's not fun with these persistent network issues.

I'm not a network engineer. But i really doubt this is on my end as POE is the only problem. I work partially remote as a video editor and don't have any issues with tons of data being uploaded/downloaded. No other games have any latency issues.

I dont know what else to try

I would suggest installing WinMTR and run a trace route with the games IP address and post that info.

Nothing you gave is going to get you any help.

I have had issues in the past and it was the ISP causing the problem. If it is your ISP where the packets are being lost GGG can not do anything about it you need too.
