Subnautica 2 System Requirements

Specs pulled from the Steam store page. Worth re-checking close to launch in case Unknown Worlds bumps them based on EA performance data.

Quick read. A 5-year-old mid-range PC hits the minimum spec (GTX 1660 / Ryzen 5 2600 era). For comfortable play, aim for an RTX 3070 or better and 16 GB RAM. ROG Xbox Ally support is officially listed; Steam Deck performance is unknown until people benchmark it after launch.

Heads up
EA games often add VRAM or CPU pressure as content lands. Leave some headroom.
