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.
| Component | Minimum Spec |
|---|---|
| OS | Windows 10 64-bit (version 1909 or later) |
| CPU | Intel Core i5-8400 or AMD Ryzen 5 2600 |
| RAM | 8 GB |
| GPU | NVIDIA GTX 1060 6GB or AMD RX 580 8GB |
| DirectX | Version 11 |
| Storage | 25 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.

Subnautica 2 Recommended System Requirements
To enjoy Subnautica 2 at high settings with a smooth 60 FPS at 1080p or 1440p, you will want hardware that comfortably exceeds the minimum. The recommended specifications target a visually rich experience with full draw distances, volumetric god rays, and high-quality creature models.
| Component | Recommended Spec |
|---|---|
| OS | Windows 11 64-bit |
| CPU | Intel Core i5-12400 or AMD Ryzen 5 5600X |
| RAM | 16 GB |
| GPU | NVIDIA RTX 3060 or AMD RX 6600 XT |
| DirectX | Version 12 |
| Storage | 25 GB SSD (NVMe preferred) |
With recommended hardware the game comes alive. Coral reefs glow with dynamic lighting, deep trenches feel genuinely oppressive, and leviathan creatures render in full detail without frame drops. Sixteen gigabytes of RAM is important because the game loads large biome data sets and co-op sessions add memory overhead per connected player.
If you want to play in 4K or use ray tracing features, aim higher than the recommended tier. An RTX 4070 or better will let you crank settings to ultra at 4K while maintaining 60 FPS. Keep in mind that early access performance is still being optimized, so expect improvements over time. The developers are continuously working on optimization, and each patch typically brings measurable frame rate gains for mid-range hardware configurations.
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.
