Subnautica 2 system requirements for PC

To run the Subnautica 2 system requirements, you will need an AMD RX 5500 XT GPU, an AMD Ryzen 5 2600 CPU, 8GB of RAM, and 20GB of HDD or SSD space. 

Following on from the major success of the original Subnautica and Subnautica Below Zero, Subnautica 2 promises to send players to a whole new planet with multiplayer support. Best of all, the Subnautica 2 requirements for PC aren't particularly demanding, especially when compared to other 2025 titles. 

In order to meet the Subnautica 2 minimum requirements, you will need an NVIDIA GeForce GTX 1660 graphics card, an Intel Core i5-8400 processor, and 8GB of RAM. This will get the game up and running, but you'll almost certainly want to aim for a higher level of hardware in order to run the game at its best, and to render its horrors perfectly.

So, to play the game at its best, you can meet the Subnautica 2 recommended specs with an NVIDIA GeForce RTX 2060 GPU, an Intel Core i7-13700 CPU, and 16GB of RAM. It's a bit of a step up from the minimum requirements, but you shouldn't encounter any framerate drops at this level of hardware.
