Why Subnautica PC is demanding
The graphics demand in Subnautica PC is at the top end. Geforce RTX 3070 outscores our RTX 3060 reference, and a machine that clears Subnautica PC comfortably will clear most other things. Windows 11 appears in the requirements, which is worth checking before buying Subnautica PC. Minimum and recommended sit far apart here, which usually means Subnautica PC scales hard with the hardware you give it. Subnautica PC takes about 50 GB of disk space. DirectX 12 is named, so Subnautica PC expects a graphics driver and card from the modern era rather than merely a fast one. Subnautica PC expects 16 GB of system memory.
This reading comes from the published requirements and our own benchmark tables, not from the store listing.
Can you run Subnautica PC?
Subnautica PC scales across a wide range of hardware. GeForce GTX 1660 6GB / RX 5500 XT 6GB is enough to get in at minimum settings, while Geforce RTX 3070 8GB / RX 6700 XT 8GB and 12 GB of RAM is what it recommends for a smoother experience. Where you land mostly comes down to the settings you're willing to trade.

Projected by resolution
| Resolution | Projection | Headroom |
|---|---|---|
| 1080p | Below the bar | 0.79x |
| 1440p | Below the bar | 0.44x |
| 4K | Below the bar | 0.2x |
A projection, not a measurement. We scale the published GPU requirement by pixel count, since 1440p draws 1.78 times the pixels of 1080p and 4K draws 4 times as many, then compare against RTX 3060 / Ryzen 5 build. The publisher did not state a target resolution, so 1080p is assumed as the baseline. We hold no frame rate data, so no FPS figure is claimed. Headroom above 1 means the reference machine has room to spare at that resolution.
Common GPUs
| Graphics card | Verdict |

| GTX 1060 6 GB | Below minimum |
| GTX 1060 Laptop | Below minimum |
| GTX 1650 4 GB | Below minimum |
