These are all results of internet path congestion, and each affect your game in a different way:
Ping: the amount of time it takes for a small packet of data to be sent from your computer (or console) to your game’s server
Ping Spike: short random increases in response time that cause the game to feel choppy (e.g., someone bumps your elbow)
Jitter: longer periods of ping spikes where the game becomes unresponsive (e.g., your mouse feels sluggish)
Packet Loss: situation where your data to the game server is lost completely (i.e., like it never even happened)
These are the four main factors to consider when looking to improve your gaming experience, each of which the Cox Elite Gamer Service is built to optimize.
To see the difference, all four of these metrics are measured and displayed real-time on your "Performance" dashboard. If you ever forget which term means which, simply hover over the blue "?" square for a definition of each metric.
