Guide

What to know

Built to keep official facts, community signals, and Early Access uncertainty separated.

Research summary

Subnautica 2's current official PC baseline is higher than the earliest cached Steam text: the live Steam API lists Windows 10/11, i5-8400 or Ryzen 5 2600, 12 GB RAM, GTX 1660 6GB or RX 5500 XT 6GB, DirectX 12, broadband internet, 50 GB storage, and a 64-bit OS/CPU for minimum play. Unknown Worlds' May 1, 2026 requirements infographic defines practical performance tiers from 1080p Low 30 FPS through 4K High 60 FPS. Steam Deck is Steam Deck Verified through Valve's compatibility endpoint, with a note that external controllers may need manual selection. ROG Xbox Ally is officially named by Xbox Wire, with a default ROG Ally graphics preset, but exact public FPS and battery data are not yet available [uncertain]. Intel Iris Xe and similar integrated low-end laptop GPUs are below the stated 6 GB VRAM dedicated-GPU minimum, so they should be framed as not meeting official requirements unless later community benchmarks prove otherwise [uncertain].

  • Use Steam's current API value of 50 GB storage as the live official storage requirement.
  • Minimum target: GTX 1660 or RX 5500 XT, i5-8400 or Ryzen 5 2600, 12 GB RAM, 6 GB VRAM, 1080p Low, 30 FPS.

Content modules to include

These modules translate the keyword research into page sections, tables, tools, and update surfaces.

  • Official PC Requirements: current Steam minimum and recommended specs, with a note that Steam API storage is 50 GB.
  • Official Performance Tiers: Unknown Worlds minimum, recommended, Ultra, and Ultra++ table with GPU, CPU, OS, RAM, VRAM, resolution/preset, and FPS.
  • Can My PC Run It?: explain pass/fail logic using CPU, GPU, RAM, VRAM, DirectX 12, 64-bit OS/CPU, Windows version, and storage.
  • Low-End Laptop Guidance: dedicated laptop GPUs near or below GTX 1660 should be framed cautiously; shared-memory iGPUs are below official minimum [uncertain].
  • Intel Iris Xe Answer Box: Iris Xe is not an official supported minimum GPU and lacks the dedicated 6 GB VRAM class required by the official minimum [uncertain].
  • Steam Deck Status: Valve compatibility status, passing items, and external-controller caveat.
  • Steam Deck Best Settings Watch: start with default verified configuration, then test Low preset, 720p/800p, 30 FPS cap, FSR/upscaling if available, and reduced shadows/effects after launch benchmarks [uncertain].
  • ROG Ally Status: Xbox Wire confirmation, default ROG Ally Graphics preset, controller work, and what settings remain undisclosed.

Unconfirmed or changing details

Use official sources first: Steam API/store, Valve Deck compatibility endpoint, Unknown Worlds posts, and Xbox Wire. Mark any launch-build FPS, battery, handheld settings, low-end GPU results, Intel Iris Xe claims, co-op performance impact, and stale/cached storage discrepancies with [uncertain] until confirmed by official notes or repeatable benchmarks with visible settings and build version.

  • Exact launch-build FPS on Steam Deck LCD, Steam Deck OLED, ROG Ally, and ROG Ally X is not yet confirmed by repeatable public benchmarks in the gathered official sources [uncertain].
  • Best Steam Deck settings beyond Valve's 'performant default configuration' are not officially published; 30 FPS Low or default preset advice should be treated as provisional until launch-build tests are available [uncertain].
  • ROG Ally preset details such as resolution, upscaler, render scale, TDP, and FPS target are not publicly specified in the official Xbox Wire article [uncertain].
  • Intel Iris Xe is not named by Unknown Worlds or Steam. Because the official minimum requires a GTX 1660 6GB or RX 5500 XT 6GB, Iris Xe should be considered below official minimum, but actual launch behavior is untested here [uncertain].
  • Low-end laptop outcomes for GTX 1650, GTX 1050 Ti, MX-series GPUs, older Ryzen APUs, and shared-memory integrated GPUs are not confirmed by official benchmark tables [uncertain].
  • Storage references conflict in cached store text: the current Steam API lists 50 GB, while older cached storefront text may show 20 GB. Use 50 GB as the current official value and monitor for changes [uncertain].

Content gaps to win

  • Create a source-of-truth requirements table that reconciles Steam API, Unknown Worlds infographic, and stale cached store text.
  • Add a plain-English Iris Xe answer: it is below the official GTX 1660 6GB / RX 5500 XT 6GB minimum unless future benchmarks prove a workaround [uncertain].
  • Build a hardware checker that flags shared-memory GPUs and missing VRAM separately from CPU/RAM/storage failures.
  • Provide a Steam Deck page that starts with Valve's actual compatibility endpoint and then layers launch-build benchmark updates when available.
  • Provide a ROG Ally page that names the official default graphics preset but clearly marks missing preset details as unknown [uncertain].
  • Track Steam Deck LCD vs OLED and ROG Ally vs ROG Ally X separately once credible benchmarks exist [uncertain].
  • Make a best-settings guide based on official target tiers first, then add measured community presets with build number, device, resolution, FPS cap, and TDP.

Competitor observations

  • PC Guide covers the Unknown Worlds dev-vlog quote that Steam Deck and ROG Xbox Ally players are 'good to go', reproduces the key minimum/recommended table, and mentions the Steam Deck external-controller caveat, but it does not provide launch-build benchmarks.
  • Steam Deck HQ quickly reported Steam Deck Verified status and the dev-vlog handheld confidence, but its first article does not specify measured FPS, battery life, or final recommended settings.
  • ComicBook and similar gaming news sites amplify the Steam Deck Verified badge but mostly explain what verification means rather than giving repeatable performance data.
  • Wiki-style pages often provide rich settings language, but some statements appear speculative or inconsistent with official status; these should be treated as competitor content to surpass with clearer source hierarchy [uncertain].
  • Many competing pages blur Steam Deck, ROG Ally, and ROG Xbox Ally. A stronger page should separate Valve verification, Xbox Wire ROG Ally preset confirmation, and untested community settings.
  • Few competitors directly answer Intel Iris Xe and low-end laptop intent with the official 6 GB VRAM requirement; this is a content gap worth targeting.
FAQ

Common questions

Is this information official?
