At 8 GB, system memory is undemanding. A 64 bit version of Windows is required. At 4 GB, VRAM is a non issue for Subnautica: Below Zero.
This reading comes from the published requirements and our own benchmark tables, not from the store listing.

Projected by resolution
| Resolution | Projection | Headroom |
|---|---|---|
| 1080p | Comfortable | 28.33x |
| 1440p | Comfortable | 15.94x |
| 4K | Comfortable | 7.08x |
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.
