Our Top Picks
Thinking about playing UBOAT on PC and wondering what hardware you actually need? UBOAT is a World War II submarine simulator that released on 2 August 2024, and it builds its tension out of detailed crew management, patrol routing and time compression rather than flashy effects. The good news is that its official system requirements are modest — this is a light, well-optimised game whose published targets stop at 1080p. This guide breaks down what the developer actually asks for, which GPUs make sense at each resolution, and complete build recommendations to hit your target frame rate.
How Demanding Is UBOAT?
Not very — UBOAT is one of the lighter simulation releases of recent years. The official minimum asks for nothing more than a GeForce GTX 750 Ti 2 GB, and the recommended tier tops out at a GTX 1070 8 GB running 1080p Extreme. There is no official 1440p or 4K target at all, which tells you plenty: a budget card from several generations ago can run this game at 1080p with sensible settings, and 1440p or 4K are comfortably within reach of a modern mid-range GPU. As with any simulation, the crew and ship logic leans on the processor, but the recommended CPU is a decade-old quad-core, so a modern six-core clears that bar without effort. The one genuinely heavy number here is storage: 71 GB of install space. The figures below are the developer’s own published requirements.

Best GPU for UBOAT by Resolution
1080p
At 1080p, anything from the official recommended tier upward is plenty. A AMD Radeon RX 7600 — or a current-generation card such as the GeForce RTX 5060 or Radeon RX 9060 XT — will run UBOAT at high settings with a large amount of headroom to spare. Older cards that still comfortably clear the published spec include the GeForce GTX 1060 6 GB, GTX 1660 Super and Radeon RX 580 8 GB, all of which sit at or above the recommended tier.
1440p
Step up to the NVIDIA GeForce RTX 4070 SUPER — or a current card in the same class, such as the GeForce RTX 5070 or Radeon RX 9070 — and UBOAT will run at 1440p with everything turned up and room to spare. Note that the developer publishes no 1440p target: the official recommended spec is written for 1080p High and 1080p Extreme, so treat 1440p as well inside this game’s comfort zone rather than a stretch. This is the resolution most PC gamers target, and this class of card gives UBOAT ample headroom.
4K
UBOAT has no official 4K target, and it does not need one: the game is light enough that a modern mid-range card handles 4K comfortably. The NVIDIA GeForce RTX 4070 Ti SUPER is far more than the game requires — a GeForce RTX 5060 Ti or Radeon RX 9060 XT 16 GB is already sufficient for 4K play, and anything above that simply adds headroom. Because the published specs stop at 1080p Extreme, there is no punishing 4K preset to fight, so a flagship card is never necessary here.
CPU, RAM and Storage for UBOAT
The official CPU requirement is refreshingly low: a Core i3 at 3.1 GHz or an AMD Phenom II X3 2.8 GHz gets you in the door, while an Intel Quad Core i7-3770K or AMD Ryzen 5 1600X is the recommended tier. Any current processor — the AMD Ryzen 5 7600, for instance — is far beyond what UBOAT asks for, though a chip like the AMD Ryzen 7 7800X3D will still help in the busiest moments, when the simulation is tracking crew, ships and torpedo solutions at high time compression. Intel fans can opt for the Intel Core i5-14600K. As with the GPU, treat all of these as headroom rather than a necessity.
Memory is where template advice usually goes wrong. UBOAT asks for 6 GB as a minimum and 8 GB as recommended, so 16 GB is a comfortable modern baseline for your whole system rather than something this game itself demands; a 32 GB DDR5 kit such as the Corsair Vengeance DDR5 32GB gives you room for everything else you run alongside it. Storage matters more than usual, because the install footprint is 71 GB. Put the game on an SSD — an NVMe drive like the Samsung 990 Pro 2TB NVMe SSD keeps load times and save reloads short during a long patrol.
Recommended PC Builds for UBOAT
1080p budget build: AMD Radeon RX 7600 + AMD Ryzen 5 7600 + 16 GB DDR5 — great for high-settings 1080p, and comfortably above the official recommended spec.
1440p sweet-spot build: NVIDIA GeForce RTX 4070 SUPER + AMD Ryzen 7 7800X3D + 32 GB DDR5 + 2TB NVMe SSD — the setup most players should aim for. For UBOAT specifically it is overkill in the best way: 1440p with settings maxed, plus plenty of room for heavier games.
4K high-end build: NVIDIA GeForce RTX 4070 Ti SUPER + AMD Ryzen 7 7800X3D + 32 GB DDR5 + fast NVMe SSD — for 4K play. Since UBOAT has no official 4K target, this build is about headroom for other titles as much as it is about this one.
Is It Worth Upgrading Your PC for UBOAT?
Honestly, only if you are below the official minimum. If your graphics card is roughly a GTX 750 Ti or weaker, a modest upgrade will get you into the game at 1080p; if you already own anything from a GTX 1060 6 GB upward, you are at or above the recommended tier and have no reason to spend money for UBOAT’s sake. The 71 GB install is the one practical hurdle — if your system drive is small or still a mechanical hard drive, adding an SSD is the upgrade that will actually change how the game feels. A modern CPU helps only in the busiest simulation moments, and 8 GB of RAM is the official target, so a memory upgrade is really about your wider library rather than this title. Rather than replacing everything at once, target the weakest link in your build.
Can You Play UBOAT on a Laptop or Handheld?
Yes, easily. Because the recommended GPU is a GTX 1060-class desktop card, a gaming laptop with a modern mobile GPU such as an RTX 4050 or RTX 4060 will run UBOAT at 1080p with settings turned up, and battery life and thermals will be the only real compromises. Handhelds are a particularly good fit: the Steam Deck, ROG Ally and similar devices comfortably exceed the official minimum and can run this game at sensible settings, making it a genuinely good portable pick for long patrols. The catch is storage — 71 GB is a lot on a handheld’s drive, so plan for the space or use a fast microSD card.
How to Boost FPS in UBOAT
On a game this light, frame-rate problems usually point at something other than raw GPU power. Start by updating your drivers, closing background apps and making sure the game is installed on an SSD rather than a mechanical drive — with a 71 GB install, slow storage is a common cause of hitches. If you do need more performance, upscaling is the single biggest lever: use an in-game upscaler if one is offered, or your GPU driver’s equivalent, such as FSR or NVIDIA Image Scaling, if it is not. Beyond that, drop the most expensive settings first — typically shadows, reflections and post-processing — before lowering overall resolution. A stable frame rate always feels better than maxed-out visuals with stutter.
Graphics Settings That Matter Most in UBOAT
UBOAT is not a game where you need to agonise over the options menu. If it is not hitting your target frame rate, shadow quality, reflections and post-processing effects are the usual suspects and the first things to lower for a visible gain.
Keep textures as high as your VRAM allows — the official minimum only calls for 2 GB, so most cards have room — and use upscaling on a Quality setting if the game or your driver offers it. Because the published targets stop at 1080p, there is no need to chase a punishing preset at higher resolutions; a sensible mix will look good and run well.
Frequently Asked Questions
Can my PC run UBOAT?
The official minimum is a Core i3 at 3.1 GHz or AMD Phenom II X3 2.8 GHz, 6 GB of RAM and a GeForce GTX 750 Ti 2 GB, along with 71 GB of free storage and a DirectX 11 compatible system. For the recommended experience the developer lists an Intel Quad Core i7-3770K or AMD Ryzen 5 1600X, 8 GB of RAM and a GeForce GTX 1060 6 GB or GTX 1070 8 GB. Meet the minimum and you can play at 1080p on lower settings; meet the recommended tier and you can run 1080p at High or Extreme.
Is UBOAT demanding on PC?
No. UBOAT is light by modern standards — its recommended GPU is a GTX 1060/GTX 1070-class card and its published targets stop at 1080p, so most gaming PCs built in the last several years will run it without difficulty.
What GPU do I need for UBOAT at 1440p 60fps?
There is no official 1440p spec, but the game is light enough that a NVIDIA GeForce RTX 4070 SUPER-class card — or a current-generation equivalent such as the RTX 5070 or RX 9070 — is more than enough for 1440p at 60fps or higher with settings maxed. Cards well below that tier, including the official recommended GTX 1060 and GTX 1070, already handle 1080p Extreme, so 1440p is not a stretch.
How much RAM does UBOAT need?
The official figures are 6 GB minimum and 8 GB recommended. 16 GB is a sensible modern baseline for a gaming PC in general, but UBOAT itself does not require it, and 8 GB is sufficient for the game as published.
Do I need an SSD for UBOAT?
It is not listed as a hard requirement, but with a 71 GB install an SSD is strongly recommended to keep load times and save reloads short. An NVMe drive like the Samsung 990 Pro is ideal.
