[IN-GAME LAG COMPENSATION SOLUTION FOR COD WWII PC GAMERS]
Here are my settings that work for me in the UK. (I'm now back to 25-5 KDR ...yay!)
I found a much smoother COD WWII (Pc) game-play experience by changing my Gaming Pc from a Pc to an XBOX in device manager (this is Optional and not totally necessary - both ways work , Pc or as a console), and then adding that as a device in Geo Filter (and QoS at 70/70 sliders)
I noticed a significant improvement in game in terms of ping (40ms is the sweet spot as previously mentioned by another poster)
I have my Geo radius set to EXCLUDE the entire UK (where my IP is hosted) and set it centered to Mid-Europe. (This method should work for everyone , in your own area, as long as you check that your ping to game server is as close to 40ms as you can get (40ms is the "sweet-spot" for COD WWII on PC).
Previously i was connecting to UK servers with a low ping and getting destroyed every game. Low ping in this game is of no benefit, in fact quite the opposite.
[Setup your Geo-Filter settings as below]
Additionally, I did use Port Triggering in my setup (im not sure this is totally necessary ... but because it gave me an OPEN NAT i just left it active)
I did notice occasionally that if i wasn't using Port Triggering and just relied on UPnP, I sometimes got a Moderate NAT... with Port Triggering, i get OPEN NAT 100% of the time)
