Part 1: Can Your PC Run Subnautica 2?

If your PC already struggles with newer games, this is a fair concern. Subnautica 2 is built on Unreal Engine 5 and is more demanding than previous survival games, especially when exploring large underwater areas with real-time lighting and effects.

The real question isn’t just whether it runs—it’s how stable it stays during deeper exploration.

• Older GPUs can still run the game, but FPS drops and stutters are likely
• Mid-range PCs can handle medium settings with occasional dips in heavy scenes
• High-end PCs are needed for stable high or ultra settings

If your system already struggles with recent AAA games, you can use the specs below as a reference.
