My issue with FIFA 17 during FUT Champions Weekend League is laggy/sandy like gameplay. I am currently using an ASUS AC66U router with Merlin and it's pretty good as for as game performance (I have no issues with any game but FIFA) and I think it's down to the matchmaking. I keep getting matched up with people in Mexico and South America. It's a pain in the ass and I don't want to deal with the latency. Simply put, will netduma tell me where my opponents are located and can it ban all people in Mexico from matching up with me?
