Definition of “Lag” in League of Legends?

Lag is the delay between a player’s input and the game’s actual response, causing actions to feel slow, delayed, or unresponsive. It is most commonly caused by high network latency or an unstable internet connection, but poor computer performance can also create lag by failing to process visual and gameplay data smoothly. Severe lag can disrupt movement, delay ability casts, or cause sudden jumps in HP or champion positioning.

Lag often leads to missed skillshots, failed escapes, and poor reactions during fights, making it especially punishing in fast paced Skirmishes or objective contests. Players experiencing lag may struggle to maintain proper Positioning, giving opponents easy openings to punish them. Because of its significant impact on gameplay, competitive environments rely on stable local networks to ensure fair and consistent performance for all players.
