Thinking about playing X4: Foundations on PC and wondering what hardware you actually need? Released on 30 November 2018, X4: Foundations is an action, simulation and strategy sandbox in which you begin behind the controls of a single ship and build a space empire — exploring, trading, fighting and constructing fleets, stations and entire economies in a living universe that keeps simulating whether you are watching it or not. Despite that scale, the official PC requirements are modest for a game of this age: an NVIDIA GTX 1060 or AMD RX 5300-class card and 8 GB of RAM will get you started, while an RTX 3060 / RX 6700-class GPU and 16 GB of RAM is what the developers recommend. This guide breaks down the official system requirements, the best GPU for each resolution, and complete build recommendations for X4: Foundations.
How Demanding Is X4: Foundations?
On the graphics side, honestly not very. X4: Foundations arrived in 2018, and its official minimum GPU is a GTX 1060 or RX 5300 — both several generations old — with an RTX 3060 or RX 6700 recommended. In practice that means most gaming PCs built in the last five or six years will run it, and a modern budget card can comfortably push past 1080p. This is not a title that punishes older hardware, and it is nowhere near the hardest game of its era to run.
Where X4: Foundations does ask for something more is the processor. It is a simulation and strategy game built around a fully simulated universe: ships, stations and factories are tracked and traded with in real time, so the more your empire grows, the more work the CPU has to do. Early on you will be GPU-limited like in any other game, but once you are commanding large fleets and dozens of stations, the simulation itself becomes the bottleneck — and no graphics setting will fix that. If you are deciding where to spend money, a strong CPU and enough memory will do more for a large late-game save than a faster graphics card. The figures below come straight from the game’s official store page.

Two details from the official notes are worth repeating. First, the graphics requirement is about API support as much as raw speed: X4: Foundations requires a GPU with Vulkan 1.4 support, which any reasonably modern card and driver provides. Second, the memory figure changes with your install — 8 GB of RAM covers the base game, but 16 GB is required once all expansions are installed.
Best GPU for X4: Foundations by Resolution
1080p
At 1080p you clear the official requirement with anything from a GTX 1060 / RX 5300 upwards, and the recommended RTX 3060 / RX 6700 tier is already more than the game needs. Current-generation budget cards such as the RTX 5060 or RX 9060 XT sit comfortably above that, and the NVIDIA GeForce RTX 4060 listed here belongs in the same class. If you already own an RTX 3060, RX 6700 or anything comparable, there is no reason to upgrade for X4: Foundations at 1080p.
1440p
1440p asks for a step up from the official recommendation, but still nothing extreme. Cards in the RTX 5070 / RX 9070 bracket handle it without drama, and the NVIDIA GeForce RTX 4070 SUPER named here sits well above what this 2018 title needs at this resolution. The official recommended RTX 3060 / RX 6700 class can also handle 1440p if you are willing to trim a few settings, particularly in the early game before the simulation load builds up.
4K
4K is the one resolution where X4: Foundations benefits from a genuinely fast GPU, though even here it is far from the heaviest game you could run. An RTX 5070 Ti or RX 9070 XT-class card is a sensible target, and the NVIDIA GeForce RTX 4070 Ti SUPER fits that bracket. Upscaling helps at 4K, and it is worth remembering that once a save grows large, the CPU may limit you before the graphics card does.
CPU, RAM and Storage for X4: Foundations
The official CPU requirements are an Intel i5-4590 at minimum and a Core i7-6700 recommended — both old quad-cores, which tells you the game does not need much raw processing power to launch. What it does reward is consistent single-thread performance for the simulation, and that is where a modern chip pays off. The AMD Ryzen 5 7600 is excellent value and comfortably clears the recommended spec, while the AMD Ryzen 7 7800X3D is one of the fastest gaming CPUs you can buy and the best pick if you intend to run a sprawling late-game empire. Intel builders can consider the Intel Core i5-14600K.
For memory, the official recommendation is 16 GB, with 8 GB listed as the minimum for the base game only — the store page specifically notes that 16 GB is required if all expansions are installed. Treat 16 GB as the sensible floor, and a 32 GB kit such as the Corsair Vengeance DDR5 32GB as headroom for very large saves and long sessions. Storage is straightforward: 35 GB of space at minimum and 50 GB recommended. An SSD is strongly recommended even though the official requirements do not insist on one, and installing the game on a drive like the Samsung 990 Pro 2TB NVMe SSD keeps load times short and avoids stutter as the game streams in new sectors.
Recommended PC Builds for X4: Foundations
1080p budget build: NVIDIA GeForce RTX 4060 + AMD Ryzen 5 7600 + 16 GB DDR5 — comfortably above the official recommended spec, so high settings at 1080p with room to spare.
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, with a CPU that keeps a large empire ticking over.
4K high-end build: NVIDIA GeForce RTX 4070 Ti SUPER + AMD Ryzen 7 7800X3D + 32 GB DDR5 + fast NVMe SSD — for 4K with upscaling enabled.
Is It Worth Upgrading Your PC for X4: Foundations?
Because the official requirements are so low, X4: Foundations is rarely the reason to buy a new graphics card. A GTX 1060-class card or better already meets the minimum, and an RTX 3060-class card matches the recommendation. The more interesting question is your processor: an old quad-core like the minimum i5-4590 will run the game, but large late-game saves with many ships and stations can bog down on a chip that age, and that upgrade changes how the game actually feels. If you already have a modern six-core or better, put the money into memory instead — 16 GB is the recommended figure, and 8 GB is only enough for the base game without expansions. Moving the install onto an SSD is a cheap and worthwhile change if you are still running a mechanical drive.
Can You Play X4: Foundations on a Laptop or Handheld?
Yes, and the modest official requirements help here. A gaming laptop with a GTX 1060-class mobile GPU or better will run X4: Foundations at 1080p, and a machine with an RTX 4060 mobile GPU is well beyond the recommended RTX 3060, leaving room for higher settings and resolutions. Expect the usual laptop trade-offs — more heat, more fan noise and shorter battery life than a desktop. Handhelds are a different story: the game can run on devices like the Steam Deck or ROG Ally, but the simulation is CPU-bound, so small fleets and early saves are fine while sprawling late-game empires may struggle regardless of graphics settings. If portability matters, prioritise the strongest CPU you can get and install the game on internal storage rather than a memory card.
How to Boost FPS in X4: Foundations
Start by working out what is actually limiting you. If the GPU is the bottleneck — usually the case early on and in busy combat — enable upscaling if it is available on your hardware, then reduce the most expensive effects such as shadows, reflections and post-processing before dropping resolution. If you are deep into a save with a large empire, the CPU is more likely to be the limit, and lowering graphics settings will not help much; there, closing background applications, keeping drivers current and making sure the game sits on an SSD will do more. Either way, a stable frame rate is worth more than maximum settings in a game you may play for hundreds of hours.
Frequently Asked Questions
Can my PC run X4: Foundations?
Very likely. The official minimum is an Intel i5-4590, 8 GB of RAM, a GTX 1060 / RX 5300-class GPU with Vulkan 1.4 support and 35 GB of storage, so most PCs from the last several years qualify. The official recommended spec is an i7-6700, 16 GB of RAM, an RTX 3060 / RX 6700-class GPU and 50 GB of storage.
Is X4: Foundations demanding on PC?
Not by modern standards. It is a 2018 release whose recommended GPU is an RTX 3060-class card, so mainstream hardware handles it comfortably. The one exception is a very large late-game save, where the simulation becomes CPU-bound and a faster processor matters more than a faster graphics card.
What GPU do I need for X4: Foundations at 1440p 60fps?
A NVIDIA GeForce RTX 4070 SUPER-class card gives you plenty of headroom at 1440p, but you do not need to go that far — the official recommended RTX 3060 / RX 6700 tier can handle this resolution with a few settings reduced, particularly in the early game. Upscaling helps if you want to keep settings high.
How much RAM does X4: Foundations need?
The official minimum is 8 GB, but the developers note that 16 GB is required once all expansions are installed, and 16 GB is also the recommended figure. 16 GB is the sensible target for anyone playing seriously; 32 GB is comfortable headroom rather than a necessity.
Do I need an SSD for X4: Foundations?
Not strictly — the official requirements only ask for 35 GB of free space — but an SSD is strongly recommended. An NVMe drive like the Samsung 990 Pro cuts load times and helps avoid stutter when the game streams in new content, and it is one of the cheapest upgrades you can make.
