Since i live in the area where i can not access COD Warzone without VPN, i began using SharkVPN and NordVPN, but i always experience lag spikes so severe, that the game becomes unplayable. The ingame ping monitor shows that i have around 100 ping, but than it spikes to 500 and than to N/A (Over 1000). I've tried every method i ran into to fix this problem, which include changing my DNS, turning off crossplay, calling my provider, changing VPN servers etc. But nothing helps, did anyone face the same problem or have any ideas on how to fix it? By the way, i am the only one facing this problem, all my friends and neighbours seem ok with their ping

With vpn in the path it gets a little messy to test.

So I would first leave constant ping run to a IP like 8.8.8.8 and another one to the far vpn end point...assuming it will respond to ping. Do this all with the vpn off.

This is purely to see if you have some issue not related to the vpn.

Next you can turn on the vpn and try to ping 8.8.8.8 through the vpn. Problem is the 8.8.8.8 ip address does not represent a single machine or single location so it is highly likely they are not the same so comparisons are hard.

Pretty much this is to see if the traffic passing via the vpn gets the same ping spikes a game does. You could also try to ping the game server through the vpn but many times those will not respond to actual...

Now what might happen is all this will work fine and show no issues. In a way that is good because it means it is some issue with the game and not really a network problem.

Still vpn is software running on your machine so it could still be the program or some interaction between the vpn program and the game program.

Another thing that might show something interesting is the resource monitor event tab. If the vpn is using TCP sessions you should be able to find the session on the screen and it will actually tell you the latency. I am not sure I run my vpn on my router so its been a long time since I looked at one running on windows.
