Best Sons of the Forest settings for the AMD Radeon Vega 8 (iGPU) (2026)

On a AMD Radeon Vega 8 (iGPU) (paired with a balanced Intel Core i5-8600K-class CPU), Sons of the Forest runs at roughly 29 FPS at 1080p with our optimized settings — up from about 11FPS with everything maxed. Here's the configuration and what each setting costs.

The AMD Radeon Vega 8 (iGPU) is a entry-level graphics card with 2GB 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 29 FPS with FrameCoach's optimized settings, a clear jump from roughly 11 FPS with everything on High.

Across resolutions you can expect around 29 FPS at 1080p and 17 FPS at 1440p, dropping to roughly 10 FPS at 4K. With only 2GB 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.
