Subnautica 2 PC System Requirements: Minimum and Recommended Specs

Updated: 2026-08-073 sections

Subnautica 2 is built on a modernized version of the engine that powered the original game, but it pushes visual fidelity and world scale further. That means the minimum requirements have climbed compared to the first Subnautica. Here is what you need just to get the game running at low settings and 30 frames per second.

ComponentMinimum Spec
OSWindows 10 64-bit (version 1909 or later)
CPUIntel Core i5-8400 or AMD Ryzen 5 2600
RAM8 GB
GPUNVIDIA GTX 1060 6GB or AMD RX 580 8GB
DirectXVersion 11
Storage25 GB available space (SSD recommended)

At minimum settings you can expect 720p or 1080p at low quality with reduced draw distance. Underwater volumetric lighting and creature animations will be simplified. The game remains playable, but the atmospheric beauty that defines Subnautica will be diminished. If you are right at the minimum line, consider upgrading your GPU first, as the underwater rendering pipeline is heavily graphics-bound.

One important note: Subnautica 2 benefits significantly from an SSD. Loading biomes and streaming creature assets from a traditional hard drive can cause stuttering and pop-in. If your system still uses a mechanical HDD as its primary drive, installing the game on even a budget SATA SSD will dramatically improve smoothness.

Laptop Specs and Common Performance Tips

Many players ask whether their gaming laptop can run Subnautica 2. The short answer is yes, if it meets the desktop-equivalent specs. Laptops with an RTX 3050 or 3060 mobile GPU and 16 GB of RAM will handle the game well at medium-high settings. Just make sure the game is using your dedicated GPU and not the integrated graphics chip.

Here are the most common fixes if Subnautica 2 runs poorly on a machine that should handle it:

  • Update GPU drivers: Download the latest NVIDIA or AMD drivers before launching. Outdated drivers are the number one cause of poor performance.
  • Install on an SSD: Streaming stutter is almost always caused by slow storage. Move the game to an SSD.
  • Close background apps: Browsers with dozens of tabs compete for RAM and CPU. Close them before diving.
  • Lower water quality and shadows first: These two settings have the biggest impact on FPS in underwater scenes.
  • Disable ray tracing: If enabled, ray tracing can cut FPS in half on mid-range cards.

Subnautica 2 is well optimized for an early access title, but the massive open ocean and real-time creature simulation will always demand decent hardware. If you are building or upgrading a PC specifically for this game, prioritize a solid GPU and an NVMe SSD above all else.

Frequently Asked Questions

If you have at least an Intel i5-8400 or Ryzen 5 2600 CPU, 8 GB of RAM, and a GTX 1060 or RX 580 GPU, you can run the game on minimum settings. For a smooth high-settings experience, aim for an RTX 3060 and 16 GB of RAM.

An SSD is strongly recommended but not strictly required. Running the game from a mechanical hard drive will cause noticeable stuttering and asset pop-in. Even a basic SATA SSD dramatically improves smoothness.

Eight gigabytes meets the minimum requirement and will run the game, but 16 GB is strongly recommended. Co-op multiplayer and large biome streaming consume extra memory, and 8 GB may cause stuttering in busy areas.

Subnautica 2 runs on the Steam Deck at medium-low settings and 30 to 40 FPS. It is playable but not ideal for long sessions. More powerful handhelds with dedicated GPUs will perform better.
