Ping measures how long it takes for game data to be sent from your console or PC to the FC Game Data Centers and back. This is sometimes referred to as ‘latency’. A low ping means that packets of game data are sent quickly to and from the FC Game Data Centers.
Packet loss is the measurement of the number, or percentage, of packets that fail to successfully make the round trip to the FC Game Data Centers and back. Having no packet loss means that packets of game data are reliably sent to and from the game data centers.
Jitter is the measurement of the changes to your ping values over time. If one second your ping is 20ms, the next it’s 90ms, then it’s 120ms—you’re experiencing jitter. Low or no jitter means that game data packets are being sent to and from the Game Data Centers consistently.
