What it does
Crowd density is commonly CPU-heavy because every actor needs animation, navigation and simulation work.
Games may also call it: NPC Density, Population Density
Decision guide
Lower it when
Lower it when cities, hubs or traffic cause poor 1% lows while GPU usage is below full load.
Keep it high when
Keep it higher when world population matters and the CPU still holds the target frame time.
Handheld advice
This is one of the first settings to test during a CPU bottleneck.
Restart
Usually not required
Some games still apply changes only after reloading a scene or restarting.
Do not overread the meter
The exact effect depends on whether density changes are applied immediately or after reloading an area.
