Best Little Nightmares III settings for the AMD RX 590 (2026)

On a AMD RX 590 (paired with a balanced Intel Core i5-8600K-class CPU), Little Nightmares III runs at roughly 67 FPS at 1080p with our optimized settings — up from about 44FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD RX 590 is a entry-level graphics card with 8GB of VRAM, and Little Nightmares III is a moderately demanding game. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 67 FPS with FrameCoach's optimized settings, a clear jump from roughly 44 FPS with everything on High.

Across resolutions you can expect around 67 FPS at 1080p and 61 FPS at 1440p, dropping to roughly 34 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

Resolution	All-High FPS	Optimized FPS
1080p	44	67
1440p	26	61
4K	15	34

💡 Little Nightmares III: Unreal Engine 5 - the fixed cinematic camera hides upscaling artifacts well; lower Lumen GI first.

🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.

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.

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.
