Abstract

Response lag in digital games is known to negatively affect a player’s game experience. Particularly with networked multiplayer games, where lag is typically unavoidable, the impact of delays needs to be well understood so that its effects can be mitigated. In this paper, we investigate two aspects of lag independently: latency (constant delay) and jitter (varying delay). We evaluate how latency and jitter each affect a player’s enjoyment, frustration, performance, and experience as well as the extent to which players can adjust to such delays after a few minutes of gameplay. We focus on a platform game where the player controls a virtual character through a world. We find that delays up to 300ms do not impact the players’ experience as long as they are constant. When jitter was added to a delay of 200ms, however, the lag was noticed by participants more often, hindered players’ ability to improve with practice, increased how often they failed to reach the goal of the game, and reduced the perceived motion quality of the character.
