What it does
Chromatic aberration is normally almost free and is purely a presentation preference.
Decision guide
Lower it when
Disable it when you want a cleaner image or the color fringing is distracting.
Keep it high when
Keep it only when you like the intended cinematic look.
Handheld advice
Do not expect an FPS gain from disabling it.
Restart
Usually not required
Some games still apply changes only after reloading a scene or restarting.
Do not overread the meter
The effect can be bundled into a larger post-processing toggle.
