Command Line Parameter

-mtu number

Sets the MTU size for client-generated packets.

  • MTU (Maximum Transmission Unit) is a measurement representing the largest data packet that a network-connected device will accept. Typically in internet based TCP networks.
  • Today, the typical MTU size for games is between 1400-1500 bytes. Default for City of Heroes is 548.
  • Setting the MTU size too high can cause "fragmented" network packets which will lower performance. You also don't want to set it too low or network efficiency will take a hit. Getting the right MTU size in Windows (or other OS) can help with network connections that have a lot of latency. The optimum MTU size will vary based on the computer system.


Example

-mtu 548
