This need to communicate causes a delay between the clients and the server, and is the fundamental cause behind lag. While there may be numerous underlying reasons for why a player experiences lag, most common reasons are poor connection between the client and server, or insufficient processing in either the client or the server.
Netcode is a blanket term most commonly used by gamers relating to networking in online games, often referring to synchronization issues between clients and servers.. Players often blame "bad netcode" when they experience lag or reverse state transitions when synchronization between players is lost.
Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag , as it is known in gaming circles , refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games. [ 1 ]
Input lag or input latency is the amount of time that passes between sending an electrical signal and the occurrence of a corresponding action.. In video games the term is often used to describe any latency between input and the game engine, monitor, or any other part of the signal chain reacting to that input, though all contributions of input lag are cumulative.
In video games, an unintentional or unexpected delay between the start and end of a process, usually to a detrimental effect on gameplay. Lag can occur in any of the many different processes in a video game, to vastly differing effects depending on the source: Frame lag: A direct delay in the rate at which a frame is processed. This is usually ...
RTT is a measure of the amount of time taken for an entire message to be sent to a destination and for a reply to be sent back to the sender. The time to send the message to the destination in its entirety is known as the network latency, and thus RTT is twice the latency in the network plus a processing delay at the destination. The other ...
Graphical depiction of contributions to network delay. Network delay is a design and performance characteristic of a telecommunications network. It specifies the latency for a bit of data to travel across the network from one communication endpoint to another. [1] [2]: 5 It is typically measured in multiples or fractions of a second. Delay may ...
The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
