The RTX 5090 is the fastest consumer GPU available, so the real question for Sons of the Forest is not whether it runs, but how far past your monitor's refresh rate it goes at 1440p.

Quick Answer

The RTX 5090 runs Sons of the Forest at 1440p maxed at around 160-200 fps, with the dense foliage starting to load the GPU. At 1440p the card has comfortable headroom for a high-refresh panel.

1440p Performance

At 1440p maxed, the RTX 5090 holds Sons of the Forest around 160-200 fps, with the game's dense foliage beginning to give the GPU real work compared to 1080p. Co-op adds CPU load that can lower frame rates in busy moments, but the card stays comfortably above high-refresh targets.

Settings And Upscaling

Max every setting at 1440p; the RTX 5090 absorbs it. DLSS is not needed to hit high frame rates here, though DLSS Quality adds extra headroom if you want frames to spare. A 1440p 165Hz or 240Hz panel is the ideal pairing for this title on the 5090.

RTX 5090 In SA

The RTX 5090 is currently stocked at Evetech in the R55,000-R65,000 band depending on model. For Sons of the Forest at 1440p it is overkill, suiting buyers who also play demanding current 4K titles. Pair it with a Ryzen 7 9800X3D and a 1440p 240Hz panel to use the frame rates. For storage, keep Sons of the Forest on the NVMe SSD so its dense forest streams smoothly; the survival map loads quickly off a Gen4 drive, and co-op sessions benefit from the faster asset loading when players spread out.

FAQ

What FPS does the RTX 5090 get in Sons of the Forest at 1440p?

Around 160-200 fps maxed, with the dense foliage starting to load the GPU more than it does at 1080p.

Do I need DLSS at 1440p on a 5090?

Not to hit high frame rates. DLSS Quality adds extra headroom if you want frames to spare, but native rendering already runs well.

Is the RTX 5090 overkill at 1440p for this game?

Somewhat. The card has headroom at 1440p; it suits buyers who also play demanding current titles at 4K alongside it.

TIP

the RTX 5090 holds Sons of the Forest at 160-200 fps; enable DLSS Quality for extra headroom or move to 4K to load the GPU fully.
