# How to Change Max Players on Your ATS Server (/docs/american-truck-simulator/player-slots)



import { Step, Steps } from 'fumadocs-ui/components/steps';

Setting Max Players [#setting-max-players]

In `server_config.sii`:

```
 max_players: 8
```

Player Limit [#player-limit]

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

AI Traffic Settings [#ai-traffic-settings]

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.
