💡 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.
Vegetation / Foliage DensityLow+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.
Effects QualityLow+7% FPS
Fire, water and combat effects. Drops most during cannibal raids — lower it to stay steady.
Ambient OcclusionOff+5% FPS
Soft contact shadows in the undergrowth. Subtle — safe to lower.
Post ProcessingLow+4% FPS
Bloom and depth of field. Low is a cheap, clean win.
Texture QualityUltra-2% FPS
Surface sharpness — nearly free if it fits your VRAM. On 8GB cards keep it at High rather than Ultra.
Anisotropic Filtering16xbaseline
Keeps the ground sharp at distance. Effectively free — leave it at 16x.
