PC System Requirements
The PC system requirements below are the storefront tiers listed on October 8, 2026. Both require a 64-bit processor and operating system and a broadband internet connection. The current listing does not attach resolution or frame-rate guarantees to these tiers. Requirements may change during Early Access.
Component | Minimum | Recommended |
|---|---|---|
Operating system | Windows 10/11 (64-bit) | Windows 11 (64-bit) |
CPU | Intel Core i5-8400 / AMD Ryzen 5 2600 | Intel Core i7-13700 / AMD Ryzen 7 7700X |
Memory | 12 GB RAM | 16 GB RAM |
Graphics | GeForce GTX 1660 6GB / RX 5500 XT 6GB | GeForce RTX 3070 8GB / RX 6700 XT 8GB |
DirectX | Version 12 | Version 12 |
Network | Broadband internet connection | Broadband internet connection |
Storage | 50 GB available space | 50 GB available space |
Earlier provisional Early Access guidance listed a GTX 1660 minimum tier targeting 1080p at 30 FPS on Low, and an RTX 2060 or RX 5600 XT recommended tier targeting 1440p at 60 FPS on Medium, with around 25 GB of storage. Those were provisional targets rather than measured performance guarantees for the current requirements.
Requirements Notes
Requirement | Notes |
|---|---|
12 GB minimum RAM | Reflects Unreal Engine 5's memory footprint and the larger world. |
DirectX 12 required | Both tiers require DirectX 12, so DirectX-11-only GPUs are not supported. This aligns with Unreal Engine 5's rendering pipeline. |
50 GB available storage | The current storefront lists 50 GB of available storage for both tiers. The earlier provisional estimate was around 25 GB. |
Handheld Performance
Subnautica 2 supports two handheld targets in the launch build: Valve's Steam Deck and the ROG Xbox Ally line.
Steam Deck
Steam Deck carries an official Verified rating. The default preset is the lowest graphics tier with ultra-performance upscaling, locked to a 30 FPS target.
ROG Xbox Ally and Ally X
The ROG Xbox Ally and Ally X ship with a dedicated graphics preset enabled by default. The preset is tuned for handheld power limits and can be adjusted up or down. Approximate launch performance figures:
Device | Resolution | Power | Frame Rate |
|---|---|---|---|
ROG Xbox Ally X | 1080p | 30 to 35 W | Averages 50 to 60 FPS, drops into the 40s in heavy scenes. |
ROG Xbox Ally X | 1080p | 20 W | Averages 40+ FPS, drops into the 30s. |
ROG Xbox Ally | 900p | 18 W | Averages 40+ FPS. |
Supported Languages
Subnautica 2 supports the following languages at launch:
English
German
Korean
Portuguese (Brazil)
Spanish (Latin America)
French
Japanese
Simplified Chinese
Italian
As of October 8, 2026, the current storefront also lists Russian and Ukrainian, bringing the listed language total to eleven. English is the language marked for full audio support. The nine-language list above records the launch offering.
Additional language support may be added during the Early Access period.
Cross-Platform Multiplayer
Players on different PC storefronts (Steam, Epic, Microsoft Store) and on Xbox Series X|S can play together in the same up-to-four-player co-op session through full crossplay. See Crossplay for supported platforms and current limitations.
Performance Considerations
As an Early Access title built in Unreal Engine 5, performance is an ongoing area of optimization throughout development. Players should expect iterative work across these areas during Early Access:
Draw distance and level-of-detail transitions in large open biomes.
Loading times when transitioning between biome areas.
Memory usage with extended play sessions.
Multiplayer network performance with up to four players in the same world.
System requirements may be updated during the Early Access period as the game is optimized and new content is added.
On PC the game supports NVIDIA DLSS upscaling and Frame Generation. A June 1, 2026 patch upgraded the integration to DLSS version 4.5 and resolved crashes and settings-persistence problems tied to it, along with restoring Frame Generation availability on builds where it had been missing.
October performance and crash fixes
Buddy System Hotfix 2 on October 6, 2026 changes VSync so it is disabled when DLSS Dynamic Frame Generation is selected. It also fixes an Xbox memory leak caused by audio commands accumulating while the game is paused or constrained.
The hotfix updates crash diagnostics and stack-trace collection, re-enables crash reporting and crash-on-launch logging after hang issues were resolved, and updates supporting components across supported platforms. Players using community mods were asked to disable them after updating until the mod creators update compatibility.
