Best Sons of the Forest settings for the NVIDIA RTX 4090 (2026)

On a NVIDIA RTX 4090 (paired with a balanced Intel Core i9-14900K-class CPU), Sons of the Forest runs at roughly 78 FPS at 4K with our optimized settings — up from about 79FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA RTX 4090 is a flagship 4K-class graphics card with 24GB of VRAM, and Sons of the Forest is a demanding, graphically heavy game. Paired with the Intel Core i9-14900K, it runs well at 4K — about 78 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 152 FPS at 1080p and 138 FPS at 1440p, dropping to roughly 78 FPS at 4K. Its 24GB of VRAM is plenty for Sons of the Forest, so textures can stay maxed. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.

Resolution	All-High FPS	Optimized FPS
1080p	152	152
1440p	140	138
4K	79	78

💡 Sons of the Forest: Dense forests are the heaviest load and partly CPU-bound; lower Vegetation Density first.

Recommended settings

Upscaling — DLSSOff

Supports DLSS and FSR. The biggest single FPS gain — turn it on first, especially in dense forest where the GPU works hardest.

Texture ResolutionUltra-2% FPS

Surface sharpness — nearly free if it fits your VRAM. On 8GB cards keep it at High rather than Ultra.

GrassHighbaseline

The thick forest is the whole game — and the heaviest setting. Lowering it is the single biggest FPS gain among the trees.

Shadow QualityHighbaseline

Shadow resolution and range under the canopy. High is a big saving over Ultra with little visible loss.

Draw DistanceHighbaseline

How far the island renders. Heavy, and it leans on the CPU — lowering it causes mild pop-in on distant trees.

Fog QualityHighbaseline

Atmospheric fog over the island. A cheap trim for a modest FPS gain.

WaterHighbaseline

Ocean and lake detail. Lower it if you spend little time near the coast.

Ambient OcclusionHighbaseline

Soft contact shadows in the undergrowth. Subtle — safe to lower.

Anisotropic Textures16xbaseline

Keeps the ground sharp at distance. Effectively free — leave it at 16x.
