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 FPSwith 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 |
