Subnautica 2 System Requirements, Specs, 4K Fix, and Settings

Check Subnautica 2 minimum and recommended system requirements, Steam specs, 4K resolution fix, PC performance settings, Steam Deck and ROG Ally caveats, and Early Access optimization notes.

Quick Answer

Subnautica 2 system requirements are currently a weak-ranking opportunity: GSC Query export shows subnautica 2 system requirements at 0 clicks / 8 impressions / average position 71 over the past 3 months.
Steam's current minimum specs are Windows 10/11, Intel Core i5-8400 or Ryzen 5 2600, 12 GB RAM, GTX 1660 6GB or RX 5500 XT 6GB, DirectX 12, broadband internet, and 50 GB storage.
Steam's current recommended specs are Windows 11, Intel Core i7-13700 or Ryzen 7 7700X, 16 GB RAM, RTX 3070 8GB or RX 6700 XT 8GB, DirectX 12, broadband internet, and 50 GB storage.
PC Gamer reports the minimum target as 1080p Low at 30 fps on a GTX 1660 / i5-8400 class system, while Early Access optimization can still change FPS, stutter, and settings behavior.
If 4K is missing, use the known-issues page first: PC Gamer's tested low-risk path is switching to fullscreen, applying, and restarting before touching config files.
For FPS, the first settings to test are global illumination, shadows, view distance, shading, and effects from Epic to High; this is an evidence-backed performance entry, not a full best-settings page.
The www version of this URL appeared in GSC Pages export at 0 clicks / 14 impressions / average position 43.14, so canonical host cleanup matters as much as content wording.
Steam Deck and ROG Ally questions should be routed to the dedicated Deck page when the player asks about Verified status, handheld settings, performance, crashes, or battery life.

Subnautica 2 PC Specs and Settings Triage

Task	Current answer	Evidence level	Where to go next
Minimum specs	Windows 10/11, i5-8400 / Ryzen 5 2600, 12 GB RAM, GTX 1660 6GB / RX 5500 XT 6GB, DirectX 12, broadband internet, 50 GB storage.	Steam confirmed	Use this as the launchable baseline, not a smooth-FPS promise.
Recommended specs	Windows 11, i7-13700 / Ryzen 7 7700X, 16 GB RAM, RTX 3070 8GB / RX 6700 XT 8GB, DirectX 12, broadband internet, 50 GB storage.	Steam confirmed	Use this for the desktop PC comfort baseline.
Low-end target	PC Gamer reports the developer spec target as GTX 1660 + i5-8400 for 1080p Low at 30 fps.	Reported / useful	Expect lower settings and watch patches before promising stable FPS.
4K option missing	PC Gamer tested a low-risk fullscreen / apply / restart path; UI scale, DPI override, and config edits are more advanced community workarounds.	Reported workaround	Use Known Issues for step order and risk labels.
FPS settings first	PC Gamer recommends dropping global illumination, shadows, view distance, shading, and effects from Epic to High before larger quality cuts.	Tested media benchmark	Use as a first performance checklist, not a universal best preset.
Upscaling limits	At PC Gamer's test time, AMD users did not have FSR and had to use TSR; Nvidia users could use DLSS Frame Generation.	Reported / build-sensitive	Recheck after patches before writing a full graphics guide.
Steam Deck / ROG Ally	Handhelds overlap with raw specs, but player questions need device-specific testing and should go to the Steam Deck page.	Confirmed routing	Do not duplicate the handheld tracker here.

Query export shows subnautica 2 system requirements at 0 clicks / 8 impressions / avg position 71.

Confirmed

4K resolution issue

PC Gamer reports a missing 4K resolution-option issue and a tested fullscreen / apply / restart path before advanced workarounds.

Reported

Performance settings

PC Gamer benchmarked five high-impact graphics settings to lower from Epic to High: global illumination, shadows, view distance, shading, and effects.

Reported

Steam Deck overlap

Steam Deck and handheld compatibility queries are better served by the dedicated Steam Deck page unless the task is raw PC specs or minimum requirements.

Confirmed

Performance state

Early Access can shift with patches

Confirmed

Settings guide split

Do not create a standalone graphics settings page until GSC or repeated community evidence shows sustained settings/performance demand.

Confirmed

What Is Still Unknown

Best low-end settings

Needs direct testing or trustworthy reports tied to game build, GPU driver, hardware, resolution, upscaling, and FPS target.

Post-patch upscaling options

PC Gamer's test found no FSR at that time; recheck the graphics menu after patches before making a durable AMD / Intel recommendation.

Late-game FPS

Performance can vary by biome and progression, so early-area FPS does not prove late-game stability.

Minimum and recommended specs

Steam is the source of truth for the live requirements. The current minimum row is Windows 10/11, i5-8400 or Ryzen 5 2600, 12 GB RAM, GTX 1660 6GB or RX 5500 XT 6GB, DirectX 12, broadband internet, and 50 GB storage.

The current recommended row is Windows 11, i7-13700 or Ryzen 7 7700X, 16 GB RAM, RTX 3070 8GB or RX 6700 XT 8GB, DirectX 12, broadband internet, and 50 GB storage.

The content should separate minimum specs from comfortable play. Minimum means launchable or baseline-supported; it does not guarantee smooth FPS, stable co-op, high settings, or a good handheld experience.

4K and performance settings entry point

The 4K-resolution issue belongs in Known Issues, but this page should flag it because many players arrive here from hardware and display questions. The safest first action from PC Gamer's test is fullscreen, apply, restart; UI scale, DPI override, and config edits should remain clearly labeled as more advanced.

For FPS and stutter, PC Gamer's most useful tested entry is simple: lower global illumination, shadows, view distance, shading, and effects from Epic to High before making broader quality cuts.

This is enough for a specs page and not enough for a standalone best-settings guide. A real settings page needs build date, GPU, driver, resolution, upscaling, FPS average, 1% lows, and a late-game check.

Steam Deck and handheld notes

Steam Deck searchers need a different answer from desktop-PC spec searchers. If the question is Verified status, Steam Deck settings, ROG Ally, not working, or handheld performance, route the user to the dedicated Steam Deck page.

This system requirements page should still mention handheld caveats because CPU/GPU requirements affect Deck, ROG Ally, and lower-end laptops, but it should not duplicate the full compatibility tracker.

Add tested presets, battery expectations, control issues, and handheld crash notes only after the live build can be checked and the result can be tied to a specific game version.

Early Access performance caveat

Performance advice should be versioned. A patch can make old settings guidance misleading, so every test note should include game version, test date, GPU driver or device model, graphics preset, resolution, and FPS target.

This page can later become a traffic magnet if it adds real FPS tables, but publishing guessed settings now would weaken trust. PC Gamer's testing gives a safe first settings checklist, not a universal preset.

The first content split should be based on evidence: keep broad PC specs here, keep Deck and ROG Ally details on the Steam Deck page, and only create low-end settings or FPS pages if GSC and community reports repeat the same task.

FAQ

Can my PC run Subnautica 2?

Compare your hardware with Steam's minimum and recommended specs first. Minimum currently means i5-8400 / Ryzen 5 2600, 12 GB RAM, GTX 1660 6GB / RX 5500 XT 6GB, DirectX 12, and 50 GB storage; recommended currently means i7-13700 / Ryzen 7 7700X, 16 GB RAM, RTX 3070 8GB / RX 6700 XT 8GB, DirectX 12, and 50 GB storage.

Will Subnautica 2 run on Steam Deck?

Use the dedicated Steam Deck page for Verified status, settings, ROG Ally, crashes, black screens, and handheld performance. This system requirements page covers the broader PC spec baseline.

What are the minimum Subnautica 2 specs?

Steam currently lists Windows 10/11, Intel Core i5-8400 or AMD Ryzen 5 2600, 12 GB RAM, GeForce GTX 1660 6GB or RX 5500 XT 6GB, DirectX 12, broadband internet, and 50 GB storage. Treat that as a baseline, not a promise of smooth FPS or high graphics settings.

What Subnautica 2 graphics settings should I lower first?

Use the five-setting performance entry first: global illumination, shadows, view distance, shading, and effects from Epic to High. This is based on PC Gamer testing, but a final preset still needs build-specific testing.

Why is 4K missing in Subnautica 2 settings?

PC Gamer reports a missing 4K resolution-option issue. The low-risk tested path is switching to fullscreen, applying the change, and restarting before trying advanced UI scale, DPI override, or config-file edits.

Will performance improve after Early Access launch?

It can. Early Access builds often change performance, settings, and bugs across updates.
