Best Subnautica 2 settings for the NVIDIA RTX 4070 (2026)

On a NVIDIA RTX 4070 (paired with a balanced AMD Ryzen 9 5950X-class CPU), Subnautica 2 runs at roughly 92 FPS at 1440p with our optimized settings — up from about 92FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA RTX 4070 is a strong 1440p graphics card with 12GB of VRAM, and Subnautica 2 is a moderately demanding game. Paired with the AMD Ryzen 9 5950X, it runs great at 1440p — about 92 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 153 FPS at 1080p and 92 FPS at 1440p, dropping to roughly 70 FPS at 4K. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.

Recommended settings
Upscaling — DLSSOff
Subnautica 2 is built on Unreal Engine 5 and supports upscaling. Enable it first for a big, low-cost FPS gain.
Global Illumination (Lumen)Mediumbaseline
UE5 Lumen lighting — the single heaviest setting underwater. Medium is a big saving over Epic with little visible difference in murky depths.
View / Detail DistanceHighbaseline
How far terrain and props render. Lower it a notch first if you dip in open water.
Shadow QualityHighbaseline
Shadow resolution and range. High is a strong step down from Epic.
Water & Caustics QualityMediumbaseline
The shimmering light patterns and water detail that define the look. Medium keeps the vibe while saving frames.
Flora / Foliage DensityMediumbaseline
Density of coral and plant life. Lower it for steadier FPS in dense reefs.
Effects QualityMediumbaseline
Particles, bubbles and volumetrics. Medium is plenty.
Texture QualityHighbaseline
Surface detail — cheap on FPS if it fits your VRAM.
