Best Atomic Heart settings for the AMD RX 6600 XT (2026)

On a AMD RX 6600 XT (paired with a balanced Intel Core i5-13500H (laptop)-class CPU), Atomic Heart runs at roughly 94 FPS at 1080p with our optimized settings — up from about 95FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD RX 6600 XT is a mainstream 1080p graphics card with 8GB of VRAM, and Atomic Heart is a moderately demanding game. Paired with the Intel Core i5-13500H (laptop), it runs great at 1080p — about 94 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 94 FPS at 1080p and 76 FPS at 1440p, dropping to roughly 61 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

Upscaling — FSROff
Atomic Heart (Unreal Engine 4) supports DLSS and FSR. A free FPS boost on a well-optimised game.
TexturesUltra-1% FPS
Surface sharpness - cheap if it fits your VRAM. Ultra wants 12GB+.
ShadowsHighbaseline
Shadow resolution and range. High is the value pick over Epic.
Ambient OcclusionHighbaseline
Contact shadows and depth in the colourful Soviet facility. High is a clean trade.
Volumetric FogMediumbaseline
Atmospheric fog and light shafts - a real cost. Medium keeps the mood for less.
Visual FXHighbaseline
Combat and ability effects. Lowering smooths the chaotic robot fights.
Number of ObjectsHighbaseline
Object and prop density in the scene - partly CPU-bound. High is a safe trim from Epic.
MaterialsHighbaseline
Surface shading realism on the facility's ornate surfaces. High is a clean, cheap trade.
Post ProcessingHighbaseline
Reflections, bloom and colour grading. Cheap; set to taste.
