Best Shadows of Doubt settings for the AMD RX 550 (4GB) (2026)

On a AMD RX 550 (4GB) (paired with a balanced Intel Core i5-8600K-class CPU), Shadows of Doubt runs at roughly 36 FPS at 1080p with our optimized settings — up from about 20FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD RX 550 (4GB) is a entry-level graphics card with 4GB of VRAM, and Shadows of Doubt is a relatively light game to run. Paired with the Intel Core i5-8600K, it is a real challenge at 1080p — about 36 FPS with FrameCoach's optimized settings, a clear jump from roughly 20 FPS with everything on High.

Across resolutions you can expect around 36 FPS at 1080p and 22 FPS at 1440p, dropping to roughly 12 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

💡 Shadows of Doubt: The citizen simulation is CPU-bound - graphics settings mostly tame the fog and neon, not the sim itself.
🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.
Recommended settings
Upscaling — FSRBalanced+55% FPS
The voxel-noir art style hides a lower internal resolution well. But note: this game’s biggest cost is its citizen simulation on the CPU, which no graphics setting fixes.
Graphics QualityLow+14% FPS
The master quality preset. Shadows of Doubt (Unity HDRP) has a deliberately limited menu - this drives the fog, shadows and lighting together, since the game's ray tracing / reflections / AO are largely baked and not individually toggleable.
Post Processing (Bloom / Grain)Low+4% FPS
The film-noir grain and neon bloom. Cheap to lower if you prefer a cleaner image anyway.
Texture QualityHighbaseline
Voxel surface sharpness — nearly free.
