Best Little Nightmares III settings for the RTX 4090 Laptop (2026)

On a RTX 4090 Laptop (paired with a balanced Intel Core i9-12900F-class CPU), Little Nightmares III runs at roughly 104 FPS at 1440p with our optimized settings — up from about 105FPS with everything maxed. Here's the configuration and what each setting costs.

The RTX 4090 Laptop is a high-end graphics card with 16GB of VRAM, and Little Nightmares III is a moderately demanding game. Paired with the Intel Core i9-12900F, it runs great at 1440p — about 104 FPS with FrameCoach's optimized settings. That already clears a smooth frame rate on High, so our tuning keeps the visuals as high as possible instead of chasing extra frames.

Across resolutions you can expect around 174 FPS at 1080p and 104 FPS at 1440p, dropping to roughly 80 FPS at 4K. Its 16GB of VRAM is plenty for Little Nightmares III, so textures can stay maxed. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.

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