Best Sons of the Forest settings for the AMD RX 540 (4GB) (2026)

On a AMD RX 540 (4GB) (paired with a balanced Intel Core i5-8600K-class CPU), Sons of the Forest runs at roughly 25 FPS at 1080p with our optimized settings — up from about 10FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD RX 540 (4GB) is a entry-level graphics card with 4GB of VRAM, and Sons of the Forest is a demanding, graphically heavy game. Paired with the Intel Core i5-8600K, it is a real challenge at 1080p — about 25 FPS with FrameCoach's optimized settings, a clear jump from roughly 10 FPS with everything on High.

Across resolutions you can expect around 25 FPS at 1080p and 15 FPS at 1440p, dropping to roughly 8 FPS at 4K. With only 4GB of VRAM, keep textures a notch below max in Sons of the Forest at higher resolutions to avoid stutter. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

💡 Sons of the Forest: Dense forests are the heaviest load and partly CPU-bound; lower Vegetation Density first.
🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.
Recommended settings
Upscaling — FSRBalanced+55% FPS
Supports DLSS and FSR. The biggest single FPS gain — turn it on first, especially in dense forest where the GPU works hardest.
GrassLow+14% FPS
The thick forest is the whole game — and the heaviest setting. Lowering it is the single biggest FPS gain among the trees.
Shadow QualityLow+11% FPS
Shadow resolution and range under the canopy. High is a big saving over Ultra with little visible loss.
Draw DistanceLow+10% FPS
How far the island renders. Heavy, and it leans on the CPU — lowering it causes mild pop-in on distant trees.
Fog QualityLow+7% FPS
Atmospheric fog over the island. A cheap trim for a modest FPS gain.
WaterLow+5% FPS
Ocean and lake detail. Lower it if you spend little time near the coast.
Ambient OcclusionOff+5% FPS
Soft contact shadows in the undergrowth. Subtle — safe to lower.
Texture ResolutionUltra-2% FPS
Surface sharpness — nearly free if it fits your VRAM. On 8GB cards keep it at High rather than Ultra.
Anisotropic Textures16xbaseline
Keeps the ground sharp at distance. Effectively free — leave it at 16x.
