Best Subnautica 2 settings for the NVIDIA RTX 3060 Ti (2026)

On a NVIDIA RTX 3060 Ti (paired with a balanced AMD Ryzen 9 5950X-class CPU), Subnautica 2 runs at roughly 71 FPS at 1440p with our optimized settings — up from about 71FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA RTX 3060 Ti is a strong 1440p graphics card with 8GB of VRAM, and Subnautica 2 is a moderately demanding game. Paired with the AMD Ryzen 9 5950X, it runs well at 1440p — about 71 FPS with 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 118 FPS at 1080p and 71 FPS at 1440p, dropping to roughly 62 FPS at 4K. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.

💡 Subnautica 2: Early-access Unreal Engine 5 - Lumen Global Illumination is the heaviest setting; upscaling helps a lot.
Recommended settings
Upscaling — DLSSOff
Subnautica 2 (Unity) supports Nvidia DLSS plus Frame Generation - there is currently no FSR for AMD/Intel. Enable it first for a big, low-cost FPS gain.
CloudsMediumbaseline
Volumetric clouds above the surface - can drain ~20 FPS at Epic. Medium is a big saving with little loss.
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.
