My Geo is permanently, sat over Spain. It makes all the difference for me... I actually enjoy playing this game now, which I didn't think would happen. Lol
I'm fortunate to have FTTP, (needed at my house) but I do still adjust the sliders on the QOS to around 90/90 and set it to kick in when gaming traffic is detected. There are over 50 devices including 5 Xbox consoles and my PC, plus constant streaming in every room. That's what you get when you have lots of kids and their partners at home! 😊 it definitely helps smooth things out though. Usually, my jitter doesn't go above 3ms and the rare occasional spike pops up... This all helps the gaming in my house and streaming, apart from MW.
Finding that sweet spot regarding latency, is the only way to get some good games in MW from what I've experienced.There will always be the odd duff lobby with the amount of cheats our there, but I find it funny... And a little sad. 💩
My friend progprogprog, who I spend a lot of time gaming with has forced literally, every country and his sweet spot appears to be France.
After playing with various settings I now always set my XR to strict with no ping assist, plonk it over Spain. It can take a while to find a lobby, but it's definitely worth it. 👍 👍
