Specs and platforms
Breathedge vs Subnautica: system requirements and platforms
Neither game is demanding by modern standards, but they do not run in the same places. Below are the exact PC requirements from each Steam page, followed by a full platform matrix covering Mac, Steam Deck, VR, console and mobile.
Minimum PC requirements
Recommended PC requirements
Read straight from the store pages, the two are close. Subnautica actually lists a lower minimum memory figure (4 GB) than Breathedge (8 GB), but asks for a lot more disk space (20 GB versus 7 GB). source: Steam store page: Subnautica (Unknown Worlds Entertainment) source: Steam store page: Breathedge (RedRuins Softworks / HypeTrain Digital) source: Steam store page: Subnautica (Unknown Worlds Entertainment) source: Steam store page: Breathedge (RedRuins Softworks / HypeTrain Digital) Breathedge names Nvidia GeForce cards specifically (GTX 660 minimum, GTX 1060 recommended), while Subnautica describes its minimum GPU by a benchmark score rather than a single card, which is unusually honest and worth quoting in full: "Intel HD 4600 or equivalent - This includes most GPUs scoring greater than 950 points in the 3DMark Fire Strike benchmark." source: Steam store page: Breathedge (RedRuins Softworks / HypeTrain Digital) source: Steam store page: Subnautica (Unknown Worlds Entertainment)
One thing to keep in mind reading any spec sheet: these are the figures each studio published, not benchmark results. Treat them as the floor for getting the game running, not a guarantee of a particular frame rate on a particular card.
