Lost Ark continues to do extremely well in terms of player figures. After the 1.32 million concurrent player peak registered nine days ago (Steam's second-highest peak in the all-time chart after PUBG), yesterday SteamDB measured a peak of 1.17 million concurrent players.

However, this also means queues are still very much an issue in many regions, chiefly Europe Central. In a new official update shared with the community, Amazon Games (publisher of Lost Ark in the Americas, Europe, and Oceania) said this region is at capacity, meaning the number of players per world cannot be increased and more servers cannot be added either 'due to the complexity of all the systems that need to work together'.
