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.

General tuning rules: drop Shadows, Reflection Quality andVolumetric Fog first (biggest GPU savings, low visual cost); use Render Scale / Resolution Scaling before lowering geometry; enable DLSS/FSR 3 on supported titles; cap FPS to your monitor's refresh rate to smooth frame pacing.

About Subnautica

Subnautica is a first-person game about survival in the deep sea. You control Ryley Robinson, a space traveler in the 22nd century, who crash-landed his starship on a planet that is covered almost entirely by the ocean. The protagonist needs to eat and drink, although this can be disabled in lower difficulty modes. He can desalinate oceanic water, catch or gather the seafood, and create useful tools and structures. Unlike many survival games, Subnautica has a detailed plot, in which Ryley has to uncover why his ship crashed. By exploring the ocean, finding the remnants of other crashes, and listening to the radio messages, Robinson will learn about the enormous Leviathan, the mysterious Precursors, and the reason why this planet is quarantined. The game is famous for its spectacular portrayal of the ocean and its wildlife. Robinson is equipped with a scuba diving gear that allows the player to spend most of the game underwater, although oxygen still has to be replenished. The player can dive deep and explore the world full of corals, fish, and other colorful sea creatures, often grotesque or bio-luminescent. The environment is randomly generated to improve replayability.

How the Subnautica optimization card & FPS estimate 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 settings card maps the demand tier and your hardware to a starting preset, an FPS band and an upscaler recommendation. All outputs are planning guides — verify in-game with the built-in benchmark when available.
