- RAM12 GB / 16 GB
- GPUGTX 1660 -> RTX 3070
- Storage50 GB
Quick answer
Can your PC run Subnautica 2?
If your PC has a six-core class CPU, 12 GB of RAM, DirectX 12, 50 GB of free storage, and a graphics card close to a GTX 1660 6GB or RX 5500 XT 6GB, it meets the official minimum target. For a smoother Early Access experience, the Steam page recommends a much stronger setup: Core i7-13700 or Ryzen 7 7700X, 16 GB RAM, and an RTX 3070 8GB or RX 6700 XT 8GB.
Treat the minimum line as a starting point, not a promise of high settings. Early Access builds can change performance, shader compilation behavior, memory use, and co-op stability.
