How to Change Max Players on Your ATS Server

How to set the maximum number of players on your American Truck Simulator dedicated server.

Setting Max Players

In server_config.sii:

 max_players: 8

ATS has a hard cap of 8 players. This is an engine limitation and cannot be increased regardless of configuration or hardware.

You can also control AI vehicle density:

Setting	Default	Description
`max_vehicles_total`	`100`	Total AI vehicles server-wide
`max_ai_vehicles_player`	`50`	AI vehicles visible per player
`max_ai_vehicles_player_spawn`	`50`	AI vehicles spawning near a player
`traffic`	`true`	Master toggle for AI traffic

Reducing AI vehicles can improve server performance.
