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

On a RTX 4090 Laptop (paired with a balanced Intel Core i9-12900F-class CPU), Sons of the Forest runs at roughly 89 FPS at 1440p with our optimized settings — up from about 91FPS with everything maxed. Here's the configuration and what each setting costs.

The RTX 4090 Laptop is a high-end graphics card with 16GB of VRAM, and Sons of the Forest is a demanding, graphically heavy game. Paired with the Intel Core i9-12900F, it runs well at 1440p — about 89 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 131 FPS at 1080p and 89 FPS at 1440p, dropping to roughly 68 FPS at 4K. Its 16GB 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	131	131
1440p	91	89
4K	51	68

💡 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.
