The official Subnautica 2 PC system requirements have been confirmed, and they reveal a game with a broad target hardware range — from a minimum spec aimed at 1080p playability through to Ultra++ settings designed for 4K on the very latest GPU hardware. This guide breaks down the full Subnautica 2 PC requirements tier by tier, compares them against what the average player is actually running based on Steam hardware survey data, and helps you understand what settings and resolution you should expect to run the game at on your current hardware.
The Official Subnautica 2 PC System Requirements
Subnautica 2 publishes four tiers of PC system requirements, covering Minimum, Recommended, Ultra, and Ultra++ specifications. Each tier targets a different resolution and frame rate goal, giving players a clear picture of what hardware is needed for their preferred level of visual quality.
The Minimum specification targets 1080p gameplay and requires a GTX 1660 or equivalent GPU, 12GB of system RAM, and 6GB of VRAM. This minimum spec is notably higher than many survival games of comparable scope, reflecting the visual ambition of Subnautica 2’s alien ocean environments. Players with hardware significantly below this spec — a GTX 1060 or older architecture, for example — may encounter performance issues even at minimum settings.
The Recommended specification targets 1440p at 60 frames per second and requires an RTX 3070 or equivalent. The RTX 3070 was released in 2020 and remains a capable mid-to-high-end card for modern gaming, but it represents a meaningful step up from the 1080p minimum spec. Players targeting smooth 1440p gameplay will need to ensure their GPU at least meets this recommendation.
The Ultra specification targets higher visual settings and resolutions, requiring an RTX 4070 or equivalent. The Ultra++ specification, designed for 4K gameplay at the game’s highest visual settings, requires an RTX 5070 Ti or AMD RX 7900 XTX class hardware. These Ultra++ requirements place Subnautica 2 firmly in the category of demanding AAA-level PC games in terms of hardware needs at maximum settings.
How These Specs Compare to What Players Actually Have
The Steam Hardware Survey provides the most reliable data on what hardware the PC gaming community is actually running. As of early 2026, the most common GPUs among Steam users are mid-range cards from the GTX 1060 to RTX 3060 range, with the GTX 1060 itself remaining one of the most widely installed GPUs on the platform despite being released in 2016.
This creates a challenging situation for Subnautica 2’s early access player base. A meaningful proportion of Steam players have hardware at or below the minimum spec — a GTX 1060 with 6GB VRAM falls short of the GTX 1660 minimum requirement. These players will need to run the game at reduced settings, may experience performance issues, or may need to wait for optimisation patches before the experience is fully comfortable.
Players with RTX 2060 or RTX 2070 cards — common mid-range options from 2019 and 2020 — sit between the minimum and recommended specs. These cards should be capable of running Subnautica 2 at 1080p with reasonable settings, though hitting a consistent 60 frames per second at maximum 1080p settings may require compromises. The Recommended spec’s RTX 3070 requirement sets a clear target for comfortable 1440p gaming.
AMD GPU Considerations
AMD GPU users faced a specific challenge at Subnautica 2 Early Access launch — a DirectX 12 crash-on-startup issue affecting some AMD hardware configurations. This was addressed in the first hotfix, and AMD users who were experiencing crash-on-startup problems should ensure their game is fully updated and their GPU drivers are current before attempting to run Subnautica 2.
In terms of equivalent AMD hardware to the NVIDIA tier recommendations: the AMD RX 6700 XT is broadly comparable to the RTX 3070 at the Recommended specification level, while the RX 7900 XTX represents the Ultra++ tier alongside the RTX 5070 Ti. AMD’s RDNA 3 architecture cards (RX 7000 series) should run Subnautica 2 well across its target settings tiers.
RAM and Storage Requirements
Subnautica 2’s 12GB RAM minimum requirement deserves attention. RAM requirements have been climbing across the PC gaming landscape in 2025 and 2026, and 12GB represents a floor that some older systems may not meet without an upgrade. Players with 8GB of RAM may experience performance issues, stability problems, or reduced loading performance compared to systems meeting the 12GB minimum.
Storage requirements for Subnautica 2 should be confirmed via the current Steam store page, as Early Access games frequently see storage requirements increase as content updates are added. Ensuring you have sufficient SSD space is advisable — modern open-world games generally benefit significantly from SSD storage in terms of loading times and texture streaming performance.
Performance Improvements in the Early Access Roadmap
Unknown Worlds has confirmed that performance improvements are part of the Early Access roadmap. Hotfix 2 already delivered performance improvements specifically targeting Epic visual settings, which improved frame rates for high-end hardware users. Future optimisation passes are expected to improve performance across the hardware spectrum, potentially making the game more accessible for players running below the current minimum specification.
This is consistent with how Unknown Worlds handled performance in the original Subnautica, which improved significantly in performance terms over its Early Access period. Players on borderline hardware who find Early Access performance challenging should expect the situation to improve meaningfully as development continues.
Should You Upgrade Your Hardware for Subnautica 2?
If your hardware is at or above the GTX 1660 minimum, the game should be playable in Early Access, with performance likely to improve through future patches. If you are running a GTX 1060 or older hardware, you may want to test the game first if it is accessible through Game Pass before committing to a purchase, and await further optimisation updates before expecting a comfortable experience at reasonable settings.
For players targeting smooth 1440p gameplay, the RTX 3070 or equivalent represents the clearest hardware target. For players happy with 1080p at medium-to-high settings, hardware in the RTX 2060 to RTX 3060 range should provide a satisfactory experience after future optimisation patches land.
