After almost a week of trials, I can say that there is no significant improvement coming from the use of R2 for playing EA FC 24 in Greece, at least from my experience.
It has helped me identified the servers I am connecting to and the ping to them ( interesting fact is that I am getting 36ms on Mainz server, whilst there is a server at the souther border of my country Irakleion, where I get approximately 48ms ping and much worse gameplay).
I have tried connecting to other 3 servers with good ping (France, Netherlands, Switzerland), with no actual improvement in the gameplay.
Today, I returned back to my previous router and the game felt smoother. I don’t mean to badmouth the product for any reason, I just want to share my experience vs my expectations.
it seems like for this game, there is only magic solutions.
