Best Shadows of Doubt settings for the AMD R9 390 (8GB) (2026)

On a AMD R9 390 (8GB) (paired with a balanced Intel Core i5-8600K-class CPU), Shadows of Doubt runs at roughly 69 FPS at 1080p with our optimized settings — up from about 69FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD R9 390 (8GB) is a entry-level graphics card with 8GB of VRAM, and Shadows of Doubt is a relatively light game to run. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 69 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 69 FPS at 1080p and 64 FPS at 1440p, dropping to roughly 43 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.
Recommended settings
Upscaling — FSROff
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 QualityHighbaseline
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)Highbaseline
The film-noir grain and neon bloom. Cheap to lower if you prefer a cleaner image anyway.
Texture QualityHighbaseline
Voxel surface sharpness — nearly free.
