Method: a game's demand tier maps to a “GPU index needed for ~60 FPS at 1080p”; each GPU's relative index produces an estimate via a diminishing-returns curve, then scaled for resolution. Source: TechPowerUp GPU database (relative performance), 2026-08-29.

Frequently asked questions
Common pre-launch questions about Subnautica 2, answered from official publisher and studio announcements (verified 2026-09-20). Configuration, fix and optimization guides are added after launch.
Can my PC run Subnautica 2?
Compare your hardware to the official minimum (GTX 1660 6GB-class GPU) and recommended (RTX 3070 8GB-class GPU) specs. An SSD and 16 GB RAM are effectively required. See the system-requirements page for a full verdict. Source: Unknown Worlds Entertainment official PC requirements (2026-09-20).
What FPS should I expect in Subnautica 2?
At 1080p on a recommended-tier GPU, roughly 58 FPS on high settings before upscaling; 1440p near 38 FPS and 4K near 22 FPS. These are tier-based estimates, not benchmarks — see the optimization page.
Is Subnautica 2 worth it for a mid-range PC?
Demand tier is 7/9. It is demanding — a recent discrete GPU (RTX 3060 / RX 6700 XT class or better) is the comfortable floor for 1080p high. Pair with the optimization guide for the best preset.

How the Subnautica 2 FPS estimate and refund verdict are computed
Each game is scored on a 0–9 demand tier from its published PC requirements (and a year/genre fallback when requirements are absent). The FPS estimate compares your selected GPU's relative-performance index against the tier's required index using a diminishing-returns curve, then scales for resolution. The refund verdict compares your playtime and purchase date against the platform's published window (14 days / 2 hours on Steam and Epic; discretionary on PlayStation; 14-day capped on Xbox; no-refund policy on Nintendo eShop for downloaded software) and weighs technical defects more favourably than preference changes. All outputs are planning guides — verify in-game with the built-in benchmark when available, and confirm policy with the platform before acting.
