I know, I know, I was going to post the Commands after. I just was busy. Here is a couple things of the top of my head:
/voicemode [value] = Sets the method used to route voice network traffic. (Values: 2 = Direct, 3 = Relay, 4 = Server Relay)
/netregion [value] = Sets the region of your Server. (Values: North America = NA, Europe = EUR, Japan = JAP)
But you did reallly help me to Understand the Sim Rate. I don't exactly understand Voicemode but I know the Definition at least.
