The first choice of the "configuration" menu.
Setting the air, ground, AA, and CPU allocations to a low value results in the lightest possible mission.
This limits mission items that require a lot of processor power.
Anti Aircraft (AA) density : AA Unit Density Level, Influences the amount of anti aircraft guns in a mission - low, medium, high
Ground density : Unit Density Level, influences the number of ground troops in a mission - low, medium, high
If set ground to high. Truck convoys and trains will still not be dozens of vehicles but battles will.
Air Density : Unit Density Level, simplified performance customization - low, medium, high, advanced config for custom. Warning : Medium already consumes a lot of CPU.
In general "medium" is meant to be the right answer, but there is a reason why these configs are tied to a campaign and not every campaign in PWCG.
Depending on the kind of campaign you are running you might want to emphasize one thing over the other.
For instance, if you was doing a ground attack campaign and probably a bomber campaign as well, you would set air activity to low and ground to high. You would keep CPU allowance at medium and would tend to leave structure at medium.
You would do this more because you don't want to be bothered so much with pesky fighters than for performance reasons.
Use Medium Air with Low CPU Allowance. That will put flights in the air than low while limiting bomber flights, which suck up a lot of CPU.
If you are flying a fighter campaign you might want to set ground activity to low to save CPU for more planes.
If you are flying a ground attack campaign, do the opposite - set air to low.
In the end it is planes that take up the majority of CPU cycles with bombers being the worst offenders. Some savings can be had by reducing ground units, but a truck is not nearly as AI intensive as a plane.
For fighter campaigns you must use "medium" across the board.
Do not raise or lower things without trying medium first. See how it goes and then adjust.
CPU Allowance : Influences the amount of structures in a mission
The most critical aspect of CPU usage is how many planes are in the air and what type of planes are they. So, in simple configurations, air activity is number 1. CPU allocation comes second.
Configuring CPU allocation.
It allows you to mitigate settings that require high CPU usage and only affect bombers and escorts:
- Low: an enemy bomber flight. No friendly bomber flights. No virtual escort.
- Medium: an enemy bomber flight. A friendly bomber flight. Max virtual escorts configured for enemy flights.
- High: No limitation by processor power.
There are certain things in the game that consume lots of CPU. Bombers are apparently #1. Airplanes in general are #2. CPU allowance limits the number of bomber flights and also limits whether or not to apply escorts.
Lower value means you see fewer bombers and more unescorted flights.
If your CPU allocation is low, it is recommended that you limit strategic interceptions.
The CPU allocation configuration does not affect other configurations such as air, ground, and AA.
Also does not affect advanced configurations.
Structures density : Influences the amount of structures in a mission.
To force PWCG to load up the entire map's structures, set ground structures to high. Based on this parameter, PWCG limits ground structures in the mission area.
