So i've resynced the cloud then i've selected MW2 and i found a server with 6 ms.
I'm in Italy and that ping is literally in the place where i live.
Next, in the Geo-Filter i've added the device first without turning on the Filter.
Then, i've set my home in the same place where there is the server and then i've set the distance to 111.
After doing all the setup, i've turned on the Filter and run the game.
Now, in the game i've searched a match. It tooked some minutes but after i found a match.
After getting into this match, i found that the latency was exactly the same before filtering, around 40/50 ms.
Is there something i've missed?
Also, all the settings in the game are set to low (i have followed this guide: How to Fix High Ping in Call of Duty: Modern Warfare 2 | Netduma).
