Stars Reach System Requirements: Can Your PC Run It?

The official requirements

The RAM figure is the one to pay attention to

A 16 GB minimum and a 32 GB recommendation is notably demanding, and it is a more meaningful constraint than the GPU requirement for most people.

The GPU floor is undemanding by 2026 standards — a GTX 1070 is a card from 2016, and an RX 580 from 2017. Plenty of machines clear that bar. Far fewer clear 32 GB of RAM, which remains above the typical configuration for a mainstream gaming PC.

Why so much memory? The most plausible explanation is the terrain simulation. Stars Reach maintains a voxel-style world where terrain is a modifiable volume rather than a surface, with water that flows, fires that spread, and lava that hardens into new land. Simulated volumes of that kind are memory-hungry by nature, and the world persists rather than resetting.

The practical reading: if you are choosing what to upgrade in order to play this game, RAM is likelier to be your bottleneck than your graphics card.

How the requirements compare to other 2026 releases

Context makes a spec sheet easier to read, so it is worth placing these numbers against what else is being asked of PCs right now.

The GPU floor is genuinely low. A GTX 1070 launched in 2016 and an RX 580 in 2017, which means a card approaching a decade old clears the minimum. Very few 2026 releases set the bar that low, and it tells you the studio is not leaning on visual fidelity to sell the game.

The memory requirement points the opposite direction. 16 GB minimum is above what many mainstream gaming PCs shipped with until recently, and a 32 GB recommendation is genuinely demanding — it is the kind of figure normally associated with simulation and content-creation software rather than with games.

Read together, this is the specification of a game that is CPU and memory bound rather than GPU bound. That is exactly what you would expect from a continuous world simulation with modifiable terrain, flowing water and spreading fire, and it is a useful signal for anyone deciding where to spend upgrade money.

Why a simulation game reads differently on a spec sheet

It is worth understanding what the game is actually asking your computer to do, because it explains an otherwise odd-looking specification and helps you predict where you will run into trouble.

Most games render a world. The geometry is fixed, authored by artists, and the machine's job is to draw it convincingly from wherever you are standing. That workload is dominated by the graphics card, which is why most spec sheets lead with the GPU.

Stars Reach simulates a world. Terrain is a modifiable volume rather than a surface — you tunnel through it with the Terraformer and the hole stays. Water flows and floods. Forests burn, and the land is different afterwards. Lava hardens into new material and new land masses. Carving channels through terrain redistributes water flow. Species populations rise and collapse based on how much players hunt them.

All of that has to be held in memory and kept consistent, and none of it is work a graphics card does. It is CPU and RAM work, and it continues whether or not anyone is looking at that part of the world.

This is why the specification looks the way it does — an ancient GPU floor alongside a demanding memory requirement. It is also why the game is hard to keep stable on a single shared server, and why performance problems have dominated the Early Access launch. The thing that makes Stars Reach interesting is the same thing making it difficult to run.

For your purposes as a buyer, the takeaway is practical: judge your machine on RAM and CPU, and do not assume a strong graphics card means you are fine.

Meeting the specs does not mean smooth play

This is the part a requirements page normally cannot tell you, and it currently matters more than the hardware.

The most common complaints about the Early Access build are jerky movement, constant rubber-banding, stuttering and server lag interrupting actions. On 21 August 2026 Playable Worlds stated publicly that they are not where they want to be on server stability and general game performance, and a hotfix addressing a wide list of bugs followed on 22 August.

Rubber-banding and desync are network and server-side symptoms. They do not improve when you upgrade your graphics card, and they will affect a high-end machine and a minimum-spec machine alike.

So there are two separate performance questions here, and conflating them wastes money. 'Can my PC render this' is answered by the table above. 'Will it feel smooth' is currently answered by the state of the servers, and that is not something you can buy your way out of.

Platforms: what exists and what does not

Stars Reach is a Windows PC release. That is the extent of what is officially confirmed.

No console version has been announced. Despite reasonable search interest in whether Stars Reach is coming to PS5 or Xbox, we could not find any official commitment from Playable Worlds either way, and we are not going to manufacture a roadmap from silence.

Steam Deck compatibility has not been rated or addressed officially at the time of writing. Given a 16 GB minimum against the Deck's 16 GB of unified memory, plus a game with confirmed optimisation problems, we would not expect a good experience — but that is reasoning from specifications rather than a verified result, and we present it as such.

If either changes, this page gets updated. Until then, the honest answer to 'what can I play this on' is a Windows PC.

Everything in this section

The pages below go deeper on the performance side. If the game is running badly for you and your hardware clears the table above, start with the lag and stuttering guide — most of what people are experiencing right now is not a hardware problem.

What to upgrade if you want to play this specifically

We would put the last item first if it did not read strangely as advice. The most common reason people consider upgrading for this game is a problem that upgrading cannot solve.

1. RAM first, and by a wide margin. Going from 16 GB to 32 GB addresses the requirement the game is most demanding about, and memory pressure is the local bottleneck most likely to be hurting you.
2. An SSD next, if the game is currently on a mechanical drive. Streaming a persistent open world off spinning storage produces long freezes when entering new areas.
3. CPU third. A continuous world simulation is CPU-heavy, and the spec sheet's low GPU floor points at where the real load sits.
4. GPU last. The stated minimum is a card from 2016. If your graphics card is newer than that and you are still having problems, the graphics card is not your problem.
5. Nothing at all, if your symptom is rubber-banding. That is server-side, and no amount of hardware fixes it.
