What it does
Bloom is normally inexpensive and mainly changes the presentation of bright scenes.
Games may also call it: Light Bloom
Decision guide
Lower it when
Lower or disable it when highlights look washed out or the effect hurts clarity.
Keep it high when
Keep it when neon, magic or sunlight looks flat without it.
Handheld advice
Change it for taste, not as an early FPS fix.
Restart
Usually not required
Some games still apply changes only after reloading a scene or restarting.
Do not overread the meter
Certain cinematic implementations can cost more.
