Kerbal Space Program 2: PC System Requirements & Best Hardware to Run It (2026)

Kerbal Space Program 2 is a physics-driven spaceflight simulation — you assemble rockets, spaceplanes and landers out of individual parts, then fly them — and it arrived on February 24, 2023. That genre matters more than usual when you are picking hardware, because the load grows with whatever you build and fly: a small probe and a sprawling orbital station are very different workloads. This guide covers the official PC system requirements, the best GPU for each resolution, and complete build recommendations so you know which components actually matter before you spend anything.

How Demanding Is Kerbal Space Program 2?

Kerbal Space Program 2 is a simulation rather than a graphics showcase, and its load is unusually lopsided between CPU and GPU. The official requirements are on the steep side for this art style: the published minimum asks for an RTX 2060, GTX 1070 Ti or RX 5600 XT with 6–8 GB of VRAM and 12 GB of RAM, and the recommended spec moves up to an RTX 3080 or RX 6800 XT with 16 GB. What those numbers reflect is not heavy visual effects but the cost of keeping a physically simulated scene stable. Part count, the number of vessels in flight, atmospheric flight and docking all add CPU work, and that work does not shrink when you lower your resolution or turn down shadows — which is why a strong processor and a decent amount of memory matter at least as much as the graphics card here. For most players a modern mid-range card clears 1080p comfortably, the recommended class of GPU is the sensible target for 1440p, and 4K wants something above that. The official figures are the only requirements worth planning around.

Best GPU for Kerbal Space Program 2 by Resolution

1080p

At 1080p you are essentially clearing the official minimum, which names the RTX 2060, GTX 1070 Ti and RX 5600 XT. Those cards still do the job, as do newer equivalents such as the RTX 3060, RX 6600 and RTX 5060. The NVIDIA GeForce RTX 4060 sits comfortably above that floor and is the sensible pick if you are buying today: it will not be the part holding you back at 1080p, and it gives you room to raise visual settings without running short of VRAM. Just remember that frame rates in busy scenes are still decided largely by your CPU, not by the card.

1440p

1440p is where the official recommended tier becomes the reference point, and the published spec names an RTX 3080 or RX 6800 XT. The NVIDIA GeForce RTX 4070 SUPER is a current-generation card in that performance class; if you are shopping newer, the RTX 5070 and RX 9070 are the direct modern equivalents, while the RX 7800 XT is an older option that still meets the recommended bar. This is the resolution most players should target for KSP2 — the extra pixels cost GPU headroom, but they do not change the simulation load, so a build at this level stays balanced.

4K

4K sits above the official recommended spec, so plan on something faster than an RTX 3080 or RX 6800 XT. The NVIDIA GeForce RTX 4070 Ti SUPER is a reasonable entry point, and current-generation options such as the RTX 5070 Ti, RTX 5080 and RX 9070 XT give you more margin. Enabling upscaling, where the game and your driver stack offer it, eases the GPU load at 4K — but resolution scaling does nothing for the simulation side, so a large, complex craft can still be CPU-limited even when the GPU has headroom to spare.

CPU, RAM and Storage for Kerbal Space Program 2

The official CPU minimum — an AMD Athlon X4 845 or Intel Core i5-6400 — is a pair of old quad-cores, and the recommended list moves up to a Core i5-11500 or Ryzen 5 3600. Because KSP2’s workload scales with how much you build and how many vessels you have flying, a fast processor pays off more here than in most games, and the AMD Ryzen 5 7600 clears the recommended spec with room to spare. If you want the strongest mainstream chip for simulation-style work, the AMD Ryzen 7 7800X3D is the one to look at, since its large cache suits exactly this kind of physics-heavy, CPU-bound load. Intel builders can go with the Intel Core i5-14600K. Memory matters too: the official minimum is 12 GB and the recommendation is 16 GB, so 16 GB is the floor for a comfortable build, and a Corsair Vengeance DDR5 32GB kit gives you headroom for large saves and mods. Storage is the least dramatic part of the spec — 45 GB free at minimum and 60 GB recommended, with no drive type stated — but installing on an SSD such as the Samsung 990 Pro 2TB NVMe SSD noticeably shortens load times.

Recommended PC Builds for Kerbal Space Program 2

1080p build: NVIDIA GeForce RTX 4060 + AMD Ryzen 5 7600 + 16 GB DDR5 — comfortably above the official minimum and a good match for 1080p.

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, matching or beating the official recommended spec on every line while keeping the CPU strong for complex craft.

4K build: NVIDIA GeForce RTX 4070 Ti SUPER + AMD Ryzen 7 7800X3D + 32 GB DDR5 + fast NVMe SSD — beyond the recommended GPU tier, for 4K with upscaling where available.

Is It Worth Upgrading Your PC for Kerbal Space Program 2?

Whether an upgrade is worth it depends on where you sit relative to the official spec. If your GPU is below the minimum — anything slower than an RTX 2060, GTX 1070 Ti or RX 5600 XT — the graphics card is the first thing to fix, because without it you are not meeting the published floor at all. If you already clear the minimum, though, the calculation is different from most games: because Kerbal Space Program 2 becomes CPU-bound once your craft gets complicated, an aging processor is often the real limiter, and a CPU and platform upgrade will do more for large builds and busy scenes than another GPU tier. Memory is worth a look as well, since the official recommendation is 16 GB and going beyond that helps with heavy saves and mods, and moving the game to an SSD shortens load times for very little money. Rather than replacing everything at once, work out which component is actually holding your builds back.

Can You Play Kerbal Space Program 2 on a Laptop or Handheld?

On a laptop you need a discrete GPU at least in the official minimum class — an RTX 2060, GTX 1070 Ti or RX 5600 XT equivalent, alongside 12 GB of system memory — because integrated graphics come nowhere near the published requirements. A gaming laptop with a modern mid-range discrete GPU and 16 GB of RAM is the practical starting point for 1080p, and expect the usual trade-offs: more heat, more fan noise and shorter battery life than a desktop. Handhelds like the Steam Deck or ROG Ally are a harder sell, less because of the GPU than because of the simulation’s CPU cost — keep your craft small, expect to lower settings, and treat the official minimum spec as the honest benchmark rather than something a handheld will comfortably beat.

How to Boost FPS in Kerbal Space Program 2

Because this game is simulation-bound rather than effects-bound, the usual graphics tweaks only get you so far, and it helps to know which side of the load you are fighting. If you are GPU-limited, turn on upscaling where the game and your GPU support it (DLSS on NVIDIA, FSR on AMD, XeSS on Intel) and then reduce the most expensive visual settings — shadows, volumetric effects and post-processing are the usual suspects — before dropping overall resolution. If you are CPU-limited, which is common once a craft carries a lot of parts or several vessels are in flight, visual settings will barely move the needle: simplifying what you are flying, keeping the number of simultaneous vessels down, closing background applications and making sure you have enough RAM will do more. Either way, keep your GPU drivers current and install the game on an SSD so asset streaming is not adding to the problem.

Frequently Asked Questions

Can my PC run Kerbal Space Program 2?

Compare your build against the official numbers above. The published minimum is Windows 10 64-bit, an AMD Athlon X4 845 or Intel Core i5-6400, 12 GB of RAM, an RTX 2060, GTX 1070 Ti or RX 5600 XT, and 45 GB of free space. For a smoother experience, the recommended spec calls for a Core i5-11500 or Ryzen 5 3600, 16 GB of RAM, an RTX 3080 or RX 6800 XT, and 60 GB of space. Meeting the minimum gets you running; the recommended tier is the better target, especially once your craft get complex.

Is Kerbal Space Program 2 demanding on PC?

Not in the way a big-budget graphics showcase is — KSP2 does not lean on heavy visual effects, and it is an older release rather than a new one. But its published requirements are on the steep side for its art style, and it is genuinely CPU-heavy: the more parts and vessels you simulate, the more processor performance you need. Clearing the official minimum is the real bar.

What GPU do I need for Kerbal Space Program 2 at 1440p 60fps?

A card in the official recommended class — an RTX 3080 or RX 6800 XT, or a modern equivalent such as the NVIDIA GeForce RTX 4070 SUPER, RTX 5070 or RX 9070 — is the right target for high settings at 1440p. Keep in mind that in this game the CPU sets the ceiling once your craft gets complicated, so pair that card with a strong processor and at least 16 GB of RAM.

How much RAM does Kerbal Space Program 2 need?

The official minimum is 12 GB and the recommended figure is 16 GB, so 16 GB is the sensible target for a modern build — 8 GB does not meet the published requirement. More than 16 GB is optional, but it helps if you fly very large craft, keep long-running saves, or use mods.

Do I need an SSD for Kerbal Space Program 2?

The official requirements only specify free space — 45 GB minimum and 60 GB recommended — and do not name a drive type. That said, an SSD shortens load times and asset streaming pauses noticeably, and an NVMe drive like the Samsung 990 Pro is a good fit for a modern build.
