Packet Loss

Hey MonsterOfMash 

Definitely an odd problem you have there,
Let's dive in and see what it could be; it's definitely not a performance issue. Your PC is powerful enough!
Maybe its the routing to the server that's could be a bit inefficient.

Could you try to change and flush your DNS? 
This might do the trick; I'll leave some how-to steps below !😀

Change DNS Windows 11:
Right-click the bottom left windows icon (start menu).
Select Network Connections.
On the left you will find a tab Ethernet, here you will find an option Change adapter options.
When you clicked on this a new window will open up showing your network card, right-click your network card and select properties.
Scroll down till you find the option: Internet protocol Version 4(TCP/IPv4).
Highlight this by clicking on this once and click on Properties.

Here you will find on the bottom the DNS settings.
select the Use the following DNS server addresses.
Now fill in the DNS of Google:
Preferred DNS server: 8.8.8.8
Alternate DNS server: 8.8.4.4

Click OK and close this window.

Flushing DNS
A DNS flush on your system is often an effective solution if you’re experiencing technical problems.
Open your Start menu and type CMD
Now right-click the window and run as Administrator.
Now type here: ipconfig /flushdns
Wait till this is done and close the command prompt.

Testing with a VPN Client
Another test to see the routing of your packets is to use a VPN for a few games and see if that improves your connection.

Let me know if any of these improved the connection.
