Total simultaneous characters
Cap on all characters in the world — players, puppets and NPCs combined.

What does this setting do?
The outermost bracket around everything animate: players, puppets, armed NPCs, all counted together. -1 leaves the number to the game.
That makes this the last-resort performance brake and also the most dangerous one: once the budget is used up nothing spawns at all — and because players count towards it, a full server hits its enemies first. A server that is busy in the evening would then be empty of puppets precisely when most is going on.
For performance problems the individual caps for puppets and NPCs serve you better, because their effect is predictable.

What to watch out for
The fuller the server, the fewer enemies fit in the budget. The result is a server that feels eerily empty when many people are on.
