Recommended settings
Upscaling — FSRBalanced+55% FPS
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.
CloudsLow+16% FPS
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.
