What actually drives Insurgency: Sandstorm memory use

It is an Unreal Engine 4 server, and the AI is the expensive part. A co-op scenario filling the server with bots costs considerably more than a PvP match with the same player count and none. Mods loaded from the workshop raise the floor at startup before anything is spawned.

The mistake to avoid

Sizing from the player slots on a co-op server. Count the bots you intend to run alongside them, because that is the number driving both memory and CPU.
