What it does
Volumetrics often sample many points through the scene and can be one of the heaviest GPU settings, especially at high resolution.
Games may also call it: Volumetrics
Decision guide
Lower it when
Lower it when weather, foggy scenes or bright light shafts cause the biggest drops.
Keep it high when
Keep it higher when atmosphere is central to the game and the performance target still has headroom.
Handheld advice
Medium commonly keeps the mood while cutting a large chunk of the cost.
Restart
Usually not required
Some games still apply changes only after reloading a scene or restarting.
Do not overread the meter
Clouds and fog may be separate options in some games.
