Recommended settings
Upscaling — FSRBalanced+55% FPS
Little Nightmares III is Unreal Engine 5 with full upscaler support. Its fixed, cinematic camera hides upscaling artifacts unusually well.
Global Illumination (Lumen)Low+15% FPS
Lumen lighting drives the game’s eerie dioramas — and most of its GPU cost. High→Medium keeps the mood.
Shadow QualityLow+11% FPS
The game lives on long, soft shadows. High looks nearly identical to Epic here.
Reflections QualityLow+7% FPS
Reflections on the Spiral’s wet and glassy surfaces. Medium is a safe saving.
Effects QualityLow+5% FPS
Dust, smoke and ambient particles. Modest cost.
Post ProcessingLow+5% FPS
Depth-of-field and film effects — a big part of the diorama look, but High vs Epic is invisible in motion.
Texture QualityEpic-1% FPS
Surface sharpness. Nearly free with 6GB+ VRAM.
