At what distance a zone wakes up
Multiplier on the distance at which an encounter zone activates for an approaching player.
scum.EncounterZoneActivationDistanceMultiplier=1.000000
What does this setting do?
The island is divided into zones that only spawn enemies once a player comes close enough. This multiplier changes how early that happens. It ships as 1.0, and the developer description warns explicitly: it applies to all zones.
That makes it the most direct lever on server load in this entire group. Every active zone means enemies that have to be computed, moved and replicated to players. A multiplier of 2.0 doubles the radius – and because area grows with the square, far more zones are awake at once than the number suggests.
In the other direction it saves performance effectively. At 0.75 zones wake later, the world feels slightly emptier, and the server has noticeably less to do. On servers struggling with player numbers this is one of the first dials to reach for – more effective than lowering enemy counts overall, because the world stays populated where somebody actually is.
Do not go too low: if zones wake too late, you watch enemies appear instead of finding them. Below 0.5 that becomes visible.
Which value suits my server?
0.75 to 1.0. Waking a little later saves performance without being noticed.
1.0 (default).
1.25 to 1.5, if your server can carry the load.
What to watch out for
Twice the distance means four times the area kept awake. Raise it in small steps and watch the tick rate.
Below 0.5 a zone wakes so late that you see them pop in. That reads as a bug.
