K0NSPIRACY

Try this:
Quit the application/game/client completely Remove device from the Geo-Filter Give PC PlayStation Device Type in the Device Manager (if on PC) Resync from the Geo-Filter Map menu Re-add the device to the Geo-Filter with the manual option Set up the Geo-Filter how you like Wait 2 minutes Boot up application/game/client You'll want to ensure Ping Assist is set to 0, then see if it works better.

So is this for all platforms or just works on PC? I play on Xbox One X so would be useful to know if also works on console.

UDP protocol when used over PORT 3075 makes possible the transmission of a datagram message from one computer to an application running in another computer (not all servers use 3074)

Real world environment testing...

Thanks. I’ve done all that but struggling to see your ports on the image…I’ve just used the ports recommended on Activision and Microsoft websites. Are there any other ports that should be forwarded other than those?
Whats your take on QoS? Leave at 100% or use sliders?

Ping is king but with mw 19 and up the lower the ping the higher sbmm to compensate for it
start the game start your xbox party then turn on your geo filter, make sure you have all correct ports forwarded and upnp off, i would also get your home pin to the server you want to play on then set the circle to 200miles so you force the game to put you in that server only see how it feels if you like it stay there if you dont then close the game clear saved game data and profile then change the home pin and repeat. make sure you disable geo filter every time you close the game. if i want easier lobbies and not try as hard for me it the Washington server
Lag compression engine.so the lower your ping is the more competitive the lag compression engine is going to make your lobbies
you need to test and find out, for me when i play multiplayer i set the bandwidth to 30mb down and 10mb up for warzone i get bandwidth to 1gige and 50mb but i change the slider to 50% down and 90% up i actually have screen shots of this in the first post of this thread 
 
if you like tinkering around with things then update but if you want the most reliable build stick to 3.3.280

Yes. Around 80-90ms.
if I play low ping on the UK/Europe servers, it should be a benefit, but it’s not. Ping isn’t king in this game, neither is (a good) connection. 
 

The host of the game is always the largest icon on the map - if there is a server with a white circle around it then that is an authentication server and its ping has no impact on your game quality

That makes sense. The only way I could find a game after this happened was to close the game, change my Geo back to actual home location and relaunch.
