Performance Options
Enabling "Culling of distant units" in the Mission Generator settings can improve performance by removing some distant units from the game.
Note: Prior to DCS Liberation 2.3 culling was much more aggressive, which often resulted in player flights being removed. The information below describes the behavior for 2.3+.
Distant unit culling removes all ground units (including buildings) that are beyond the set range from any culling exclusion zone. These culling exclusion zones are placed:
- At the front line and its attached airfields, if a front line exists.
- At the closest two opposing airfields, if no front line exists.
- At all mission targets.
Culling exclusion zones can be displayed on the map using the "Display Culling Zones" display option in the Liberation toolbar. If set too large, culling will have little effect. If set too small, the game experience will suffer as many SAMs will likely be culled.
Air units are never culled. Restricting departure airfields for air units does little to limit unit counts, so does not help performance. Instead, the income scale modifiers can be used to limit the amount of aircraft the AI is able to purchase.
