The NVIDIA GTX 1660 Ti (laptop, 6GB) is a entry-level graphics card with 6GB of VRAM, and Subnautica 2 is a moderately demanding game. Paired with the Intel Core i5-8600K, it runs well at 1080p — about 61 FPS with FrameCoach's optimized settings, a clear jump from roughly 45 FPS with everything on High.

Across resolutions you can expect around 61 FPS at 1080p and 63 FPS at 1440p, dropping to roughly 41 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.

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.
