How Demanding Is Subnautica 2?
Subnautica 2 is a modest, mid-range-friendly game rather than a demanding one. Its official minimum targets hardware from around 2018–2019 — an Intel Core i5-8400 or AMD Ryzen 5 2600, 12 GB of RAM and a 6GB GeForce GTX 1660 or Radeon RX 5500 XT — while the official recommended spec is a Core i7-13700 or Ryzen 7 7700X with 16 GB of RAM and an RTX 3070 or RX 6700 XT. In practical terms, a current budget card clears the minimum comfortably, and a mainstream card from the last couple of generations covers the recommended tier. Underwater survival is not a CPU-heavy genre here: there is no large-scale simulation or massive multiplayer to feed, so a modern six-core chip is plenty, and four-player co-op and base building do not change that. The two places Subnautica 2 asks for a little more than you might expect are memory, where the official floor is 12 GB rather than the usual 8 GB, and storage, since the game wants 50 GB of space. The figures below are the official published requirements; the store page is the only place to check for updates, especially during Early Access.

Best GPU for Subnautica 2 by Resolution
1080p
For a smooth 1080p experience, the AMD Radeon RX 7600 (or a comparable card) is the sweet spot. It sits well above the official minimum of a GTX 1660 6GB or RX 5500 XT 6GB, so high settings are within reach with upscaling such as DLSS or FSR turned on for extra headroom. Current-generation alternatives in the same bracket include the GeForce RTX 5060 and Radeon RX 9060 XT, while older cards such as the RTX 3060, RTX 2060 or RX 6600 still meet or beat the official minimum for 1080p play.
1440p
Step up to the NVIDIA GeForce RTX 4070 SUPER for high-refresh 1440p at high or ultra settings. This is the resolution most PC gamers target, and this class of card sits a clear step above the official recommended RTX 3070 / RX 6700 XT, giving Subnautica 2 plenty of headroom. If you are shopping current-generation parts, the GeForce RTX 5070 and Radeon RX 9070 are the modern equivalents, and the official recommended cards — RTX 3070, RX 6700 XT and the RX 7800 XT — remain solid 1440p choices.
4K
For 4K, the NVIDIA GeForce RTX 4070 Ti SUPER is the realistic entry point, ideally paired with upscaling to keep frame rates high. Note that 4K goes beyond what the official requirements cover, since the recommended spec tops out at an RTX 3070 / RX 6700 XT, so treat it as an enthusiast target where a top-tier card and DLSS or FSR make the biggest difference. Current-generation options in this tier include the GeForce RTX 5070 Ti or RTX 5080 and the Radeon RX 9070 XT.
CPU, RAM and Storage for Subnautica 2
Pair your GPU with a capable processor: the official minimum is a Core i5-8400 or Ryzen 5 2600 and the official recommendation is a Core i7-13700 or Ryzen 7 7700X, so anything in that range is enough. The AMD Ryzen 5 7600 lands comfortably between the two and is excellent value for gaming, while the AMD Ryzen 7 7800X3D is the fastest mainstream gaming CPU if you want maximum frame rates. Intel fans can opt for the Intel Core i5-14600K, which is close to the recommended i7-13700 in games. For memory, 12 GB is the official minimum and 16 GB is the official recommendation, so 16 GB of DDR5 is the target; a 32 GB kit such as the Corsair Vengeance DDR5 32GB adds headroom for large bases and long co-op sessions but is not required. Storage is straightforward: Subnautica 2 asks for 50 GB of available space, and installing it on a fast NVMe SSD like the Samsung 990 Pro 2TB NVMe SSD will cut load times and reduce texture streaming stutter.
Recommended PC Builds for Subnautica 2
1080p budget build: AMD Radeon RX 7600 + AMD Ryzen 5 7600 + 16 GB DDR5 — clears the official minimum with room to spare and handles high-settings 1080p.
1440p sweet-spot build: NVIDIA GeForce RTX 4070 SUPER + AMD Ryzen 7 7800X3D + 32 GB DDR5 + 2TB NVMe SSD — exceeds the official recommended spec at every component, and it is the setup most players should aim for.
4K high-end build: NVIDIA GeForce RTX 4070 Ti SUPER + AMD Ryzen 7 7800X3D + 32 GB DDR5 + fast NVMe SSD — a tier above the official recommendation, for 4K with upscaling.
Is It Worth Upgrading Your PC for Subnautica 2?
If your current graphics card is a GTX 1660 6GB, an RX 5500 XT 6GB or anything newer, you already meet the official minimum and do not need to upgrade just to play Subnautica 2 — you would be upgrading for higher settings, higher resolutions or higher refresh rates. If your card is older than that, the graphics card delivers by far the biggest jump in gaming performance, so upgrade the GPU first. The official recommended tier is an RTX 3070 / RX 6700 XT-class card, which is the sensible target if you want to play at 1440p. On the CPU side, anything from a Ryzen 5 2600 or Core i5-8400 upwards is within spec, and this game is not CPU-bound enough to justify replacing a modern processor, so you can usually keep it. Memory is the one area where Subnautica 2 asks for more than many older builds carry — 12 GB minimum, 16 GB recommended — so topping up RAM is a cheap, worthwhile upgrade, as is moving the game onto an SSD with 50 GB free. Rather than replacing everything at once, target the weakest link in your build for the best value.
Can You Play Subnautica 2 on a Laptop or Handheld?
Gaming laptops with a discrete GPU in the RTX 3060 or RTX 4060 class can run Subnautica 2 well at 1080p, since the official minimum is a desktop GTX 1660 6GB / RX 5500 XT 6GB, though expect shorter battery life and more heat than a desktop. Handhelds are a different story: the official minimum calls for a 6GB desktop-class graphics card, which is more than the integrated graphics in devices like the Steam Deck or ROG Ally deliver on paper, so expect to drop resolution and settings noticeably, and results are not guaranteed. Higher-end handhelds with stronger integrated graphics get closer to the minimum. If portability matters, prioritise a device with a capable GPU and pair it with a fast microSD or SSD for storage.
How to Boost FPS in Subnautica 2
If frame rates are low, enable upscaling (DLSS on NVIDIA, FSR on AMD, or XeSS on Intel) which offers the single biggest performance gain, and turn on frame generation if your GPU supports it. Drop the most expensive settings first — shadows, volumetric effects, and post-processing — before lowering overall resolution. Keep your GPU drivers up to date, close background apps, and make sure the game is installed on an SSD. Because Subnautica 2’s official minimum is a modest 6GB card, most systems have headroom to trade visual quality for smoothness; lowering settings to hit a stable frame rate almost always feels better than chasing maxed-out visuals with stutter.
Frequently Asked Questions
Can my PC run Subnautica 2?
If your PC has at least a GTX 1660 6GB or RX 5500 XT 6GB-class GPU, an Intel Core i5-8400 or AMD Ryzen 5 2600, 12 GB of RAM and 50 GB of free storage, it meets the official minimum and can run Subnautica 2 at 1080p with adjusted settings. For the recommended experience, aim for an RTX 3070 / RX 6700 XT-class card, a Core i7-13700 / Ryzen 7 7700X-class CPU and 16 GB of RAM.
Is Subnautica 2 demanding on PC?
No — Subnautica 2 is a modest game to run. Its official minimum is a GTX 1660 6GB / RX 5500 XT 6GB with 12 GB of RAM, and the recommended tier is an RTX 3070 / RX 6700 XT with 16 GB, so mid-range hardware handles it comfortably at 1080p and 1440p.
What GPU do I need for Subnautica 2 at 1440p 60fps?
The official recommended card is an RTX 3070 or RX 6700 XT, and that tier is the sensible baseline for high-settings 1440p in Subnautica 2. A NVIDIA GeForce RTX 4070 SUPER-class graphics card sits a step above the official recommendation and gives you comfortable headroom, especially with upscaling enabled. Cards in this tier give you extra room for future titles too.
How much RAM does Subnautica 2 need?
12 GB of RAM is the official minimum for Subnautica 2 and 16 GB is the official recommendation, so 16 GB is the practical target for a modern gaming PC. Builds with 8 GB fall below the official minimum. Faster DDR5 memory also helps in CPU-limited scenes.
Do I need an SSD for Subnautica 2?
Yes, an SSD is strongly recommended for Subnautica 2 to reduce load times, and the game requires 50 GB of available space. An NVMe drive like the Samsung 990 Pro is ideal for modern games.
