Best Subnautica 2 settings for the NVIDIA GT 730 (2GB) (2026)

On a NVIDIA GT 730 (2GB) (paired with a balanced Intel Core i5-8600K-class CPU), Subnautica 2 runs at roughly 10 FPS at 1080p with our optimized settings — up from about 4FPS with everything maxed. Here's the configuration and what each setting costs.

The NVIDIA GT 730 (2GB) is a entry-level graphics card with 2GB of VRAM, and Subnautica 2 is a moderately demanding game. Paired with the Intel Core i5-8600K, it is a real challenge at 1080p — about 10 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 10 FPS at 1080p and 6 FPS at 1440p, dropping to roughly 3 FPS at 4K. The biggest free win is FSR 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.
🚀 Biggest free win: enable FSR (Balanced) — about +55% FPS for a small sharpness trade.
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 DistanceLow+10% FPS
How far terrain and props render. Lower it a notch first if you dip in open water.
Shadow QualityLow+9% FPS
Shadow resolution and range. High is a strong step down from Epic.
Water & Caustics QualityLow+9% FPS
The shimmering light patterns and water detail that define the look. Medium keeps the vibe while saving frames.
Flora / Foliage DensityLow+7% FPS
Density of coral and plant life. Lower it for steadier FPS in dense reefs.
Effects QualityLow+5% FPS
Particles, bubbles and volumetrics. Medium is plenty.
Texture QualityHighbaseline
Surface detail — cheap on FPS if it fits your VRAM.
