What it does
Adds visible rays or shafts around strong light sources. Some games implement it as a cheap screen-space effect; others use volumetrics.
Games may also call it: God Rays, Sun Shafts, Crepuscular Rays
Decision guide
Lower it when
Lower it after the biggest settings are tuned and you still need a little more headroom.
Keep it high when
Keep it higher when the effect supports the art direction and performance remains stable.
Handheld advice
Treat this as a secondary handheld tweak after resolution, upscaling, shadows and heavy lighting are under control.
Restart
Usually not required
Some games still apply changes only after reloading a scene or restarting.
Do not overread the meter
Some games implement it as a cheap screen-space effect; others use volumetrics. This score is an editorial cross-game estimate, not a measured result for every engine.
