What it does
Controls the width-to-height shape of the rendered image. Non-native ratios may crop, stretch or add black bars.
Games may also call it: Screen Aspect Ratio, Display Aspect Ratio
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 high when the visual difference is obvious and the target frame time already has enough headroom.
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
Non-native ratios may crop, stretch or add black bars. This score is an editorial cross-game estimate, not a measured result for every engine.
