Sons of the Forest benchmark on RTX 4090: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
Sons of the Forest FPS with a RTX 4090 and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 218FPS min 120Excellent | 192FPS min 112Excellent | 142FPS min 97Excellent |
| High | 283FPS min 156Excellent | 249FPS min 146Excellent | 185FPS min 127Excellent |
| Medium | 370FPS min 204Excellent | 326FPS min 191Excellent | 242FPS min 166Excellent |
| Low | 479FPS min 264Excellent | 422FPS min 247Excellent | 313FPS min 214Excellent |
| Bottleneck (estimated) | CPU 55% | CPU 49% | CPU 32% |
The percentage estimates how much of the stronger component's capability goes unused because of the other one.
This one does matter: from the Intel Core i9-14900K downwards the processor becomes the brake on the RTX 4090. There is 7% between the slowest and fastest CPU in the table. One caveat: this is at 1080p, where the CPU weighs most. At 1440p and 4K the graphics card takes over and the processor stops mattering.
DLSS performance: FPS with AI upscaling
Upscaling renders Sons of the Forest at a lower internal resolution and reconstructs the image, so you trade a little sharpness for extra frames. These are the estimated figures for the RTX 4090 with DLSS enabled, starting from its native Ultra FPS.
| Resolution | Native | DLSS Quality | DLSS Performance | + Frame generation |
|---|---|---|---|---|
| 1080p | 218 | 273 | 316 | 464 |
| 1440p | 192 | 259 | 317 | 440 |
| 4K | 142 | 206 | 263 | 350 |
Frame generation inserts intermediate frames: it raises the smoothness you see on screen, but it does not reduce input latency, so use it selectively in competitive games.
About ray tracing: every figure on this page is with ray tracing off. The RTX 4090 does have dedicated hardware for it, so you can turn it on in games that implement it. The FPS cost swings widely depending on how much ray tracing each title uses, and DLSS is exactly what people lean on to pay for it.
Estimated figures. The real gain varies by game and by the version of the technology.
Is the CPU or the graphics card holding you back?
These FPS assume a mid-range CPU that isn't a bottleneck — roughly a Intel Core i5-13400 — and 16 GB of RAM.
With that CPU, the RTX 4090 has headroom to spare in Sons of the Forest: the processor runs out before the graphics card does. A faster processor would gain you FPS; a stronger graphics card would barely help.
Is the RTX 4090 Enough for Sons of the Forest?
The RTX 4090 delivers 218 FPS at 1080p Ultra in Sons of the Forest. More than enough for 144Hz. You can comfortably play at 1440p.
At 1440p it gets 192 FPS and at 4K 142 FPS at Ultra quality.
This GPU is more than enough — you can play at 1440p or 4K comfortably
