What is Peer to Peer transfer?
Oh great, the LoL forums are now Google.
It is what it says it is. Transferring data from one station to another station.
sorry, i just saw it in the setting tab in the new LoL PATCHER/lAUNCHER
My guess is it allows you to download game updates thru other players instead of just Riot servers, thus not bogging down the game servers and allowing faster downloads of the update.
