What it does
Adjusts image brightness or mid-tone response without meaningfully changing performance. This is a visibility and calibration control, not an FPS setting.
Games may also call it: Brightness, Gamma, Black Level
Decision guide
Lower it when
Change it mainly for preference, clarity, compatibility, or frame-pacing behavior rather than raw FPS.
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
This is a visibility and calibration control, not an FPS setting. This score is an editorial cross-game estimate, not a measured result for every engine.
