Best Shadows of Doubt settings for the AMD Radeon Vega 3 (Ryzen 3000U iGPU) (2026)

On a AMD Radeon Vega 3 (Ryzen 3000U iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Shadows of Doubt runs at roughly 21 FPS at 1080p with our optimized settings — up from about 11FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD Radeon Vega 3 (Ryzen 3000U iGPU) is a entry-level graphics card with 2GB 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 21 FPS with FrameCoach's optimized settings, a clear jump from roughly 11 FPS with everything on High.

Across resolutions you can expect around 21 FPS at 1080p and 13 FPS at 1440p, dropping to roughly 7 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.
