Thinking about playing Across the Obelisk on PC and wondering what hardware you actually need? The short answer is: not much. Across the Obelisk is a co-op roguelite deckbuilder released on August 16, 2022, in which you craft decks, plot your party’s path through the kingdom of Senenthia and fight deep tactical, turn-based battles alone or with up to three friends. Because it is a 2D, card- and interface-driven game with turn-based combat, it runs happily on hardware that most modern titles would laugh at. This guide covers the official PC system requirements, what each GPU tier realistically means at 1080p, 1440p and 4K, and sensible build advice for a game that simply does not need a powerful PC.
How Demanding Is Across the Obelisk?
Across the Obelisk is very light on PC hardware, and the official minimum specifications prove it. The developer asks for a 2.0 GHz processor, 2 GB of RAM, a graphics chip with 1 GB of video memory that supports OpenGL 3.0, Windows 10 and just 1 GB of free storage. There is no published recommended specification, and that is telling. This is a turn-based deckbuilder, so the engine is drawing 2D art, card frames and interface panels rather than a fully simulated 3D world: there are no large-scale battles to simulate and no open world to stream, so it is not CPU-heavy, and there is little for a GPU to do either. A laptop with integrated graphics, a small form-factor PC or a decade-old desktop will run it at 1080p, and the same hardware will happily output 1440p or 4K, because the workload barely changes with resolution on 2D art. If you already own any gaming PC, you are well past what this game needs.

Best GPU for Across the Obelisk by Resolution
1080p
At 1080p, Across the Obelisk is content with almost anything. Any GPU that clears the official bar — 1 GB of video memory and OpenGL 3.0 support — will do, which includes integrated graphics on recent Intel and AMD chips as well as older cards such as the GTX 1050 or RX 560. You do not need a discrete card for this game at all. If you are shopping for a card anyway and want something that also handles modern 3D titles, the AMD Radeon RX 7600 — or a current-generation equivalent such as the RTX 5060 or RX 9060 XT — is enormously more than Across the Obelisk will ever ask for, so treat it as an investment in other games rather than in this one.
1440p
1440p changes very little. The game renders 2D art and interface, so the card is mostly being asked to output a larger framebuffer rather than to draw more geometry or lighting. The AMD Radeon RX 7600 is a fine sweet spot for a general-purpose build, but again it is far beyond what is required here: much older cards in the GTX 1660 or RX 5600 class, and even anything meeting the official OpenGL 3.0 requirement, will handle 1440p in this game. Upscaling is not something you should need to think about at this resolution, and an RX 9070 or RTX 5070 would be pure overkill.
4K
4K is where the official minimum starts to feel slightly thin, but only slightly: 1 GB of video memory and OpenGL 3.0 is enough to run the game, and any card with a couple of gigabytes of VRAM and a modern display output will drive a 4K panel without trouble. The NVIDIA GeForce RTX 4060 is comfortably more than the game needs, and there is no scenario in which Across the Obelisk requires a high-end GPU or upscaling at 4K. Older cards such as the GTX 1660 or RX 5600 output 4K for a 2D title just as well, and if you are buying new, an RTX 5060 or RX 9060 XT is already well past the point of diminishing returns for this game.
CPU, RAM and Storage for Across the Obelisk
Across the Obelisk is not a CPU-heavy game. The official requirement is a 2.0 GHz processor, and because combat is turn-based with no background simulation, a modern quad-core is already overkill. If you are building a general-purpose gaming PC, the AMD Ryzen 5 7600 is excellent value, the AMD Ryzen 7 7800X3D is one of the fastest mainstream gaming CPUs, and Intel buyers can look at the Intel Core i5-14600K — but none of that is necessary here, and an older Ryzen 3, Core i3 or low-power laptop chip will run the game perfectly well.
Memory is a similar story. The official minimum is 2 GB of RAM, which is a genuine reflection of how little the game needs; in practice Windows wants more than that, so 8 GB is a comfortable, inexpensive target and 16 GB covers gaming in general. A kit such as the Corsair Vengeance DDR5 32GB is far more than Across the Obelisk will ever use. Storage is simpler still: the install is about 1 GB, so any drive with a gigabyte free will do, and an SSD is a nice-to-have rather than a requirement. If you are buying storage anyway, a fast NVMe drive like the Samsung 990 Pro 2TB NVMe SSD speeds up loading across your whole library, though this game’s own load times are short either way.
Recommended PC Builds for Across the Obelisk
1080p budget build: AMD Radeon RX 7600 + AMD Ryzen 5 7600 + 16 GB DDR5 — a strong 1080p machine that treats Across the Obelisk as a trivial workload. For this game alone you could spend a fraction of that: any PC with a 2 GHz CPU, 2 GB of RAM and OpenGL 3.0 graphics is enough.
1440p sweet-spot build: AMD Radeon RX 7600 + AMD Ryzen 7 7800X3D + 32 GB DDR5 + 2TB NVMe SSD — the setup most players should aim for if they play demanding games too, since Across the Obelisk itself would be perfectly happy on far less.
4K high-end build: NVIDIA GeForce RTX 4060 + AMD Ryzen 7 7800X3D + 32 GB DDR5 + fast NVMe SSD — for 4K output in a 2D deckbuilder this is far more than required, and it makes sense mainly as a living-room or multi-purpose system that also handles heavier titles.
Is It Worth Upgrading Your PC for Across the Obelisk?
Honestly, not for Across the Obelisk. If your PC meets the official minimum — a 2.0 GHz CPU, 2 GB of RAM and a graphics chip with 1 GB of video memory and OpenGL 3.0 support — you can already play it, and no part of this game rewards a faster GPU or CPU. Upgrade only if the other games you play need it, and if you do, the graphics card still delivers the biggest jump in general gaming performance. Where this game is concerned, the cheapest fixes are the useful ones: keep Windows and your GPU drivers up to date, and on a laptop make sure the game is using the right graphics processor rather than falling back to a slower one. Spending money specifically to improve Across the Obelisk is not a good use of a budget.
Can You Play Across the Obelisk on a Laptop or Handheld?
Across the Obelisk is close to an ideal laptop and handheld game. Because the official minimum asks for only 2 GHz, 2 GB of RAM and OpenGL 3.0 graphics, almost any laptop sold in the last several years — including thin-and-light models with integrated graphics — will run it at 1080p. Gaming laptops with a discrete GPU such as an RTX 4060 or better are wildly overqualified. On handhelds like the Steam Deck and ROG Ally it runs comfortably, and its low hardware demands mean long battery life and little fan noise compared with a 3D action game. Storage is a non-issue too: at around 1 GB the install fits easily on internal storage or a microSD card. If portability matters, prioritise screen and battery quality over raw GPU power, because this game will not use it.
How to Boost FPS in Across the Obelisk
Most players will never need to touch a single setting, but if the game feels sluggish, start with the basics. Make sure your graphics drivers are up to date, close background applications, and on a laptop confirm the game is running on the discrete GPU rather than integrated graphics where both are present. Lowering the output resolution is the most reliable lever on very old hardware, and if the game exposes options for effects or similar visual quality toggles, reduce those rather than dropping everything at once. V-sync and frame caps are worth experimenting with, since a stable, capped frame rate usually feels smoother than an unlocked one that fluctuates. Finally, keep the game on whichever drive you use for everything else — at roughly 1 GB it makes almost no difference — and avoid heavy background tasks while you play.
Frequently Asked Questions
Can my PC run Across the Obelisk?
Almost certainly. The official minimum is a 2.0 GHz processor, 2 GB of RAM, a GPU with 1 GB of video memory and OpenGL 3.0 support, Windows 10 and 1 GB of free storage. Any PC or laptop from the last decade that meets those numbers will run the game, and there is no published recommended tier to worry about.
Is Across the Obelisk demanding on PC?
No. It is one of the lightest games you can install — a 2D, turn-based deckbuilder with a 2 GB memory requirement and a 1 GB install. Mid-range and high-end hardware is far beyond what it needs.
What GPU do I need for Across the Obelisk at 1440p?
Any card that supports OpenGL 3.0 with 1 GB of video memory will output 1440p, because the workload barely grows with resolution in this game. An AMD Radeon RX 7600-class card is far more than enough and really only makes sense if you also play demanding 3D titles.
How much RAM does Across the Obelisk need?
The official minimum is 2 GB of RAM. In practice Windows itself uses more than that, so 8 GB is a comfortable amount for a modern machine and 16 GB covers gaming generally. There is no scenario in which this game needs more.
Do I need an SSD for Across the Obelisk?
No. The game installs in about 1 GB and loads quickly from any drive. An NVMe drive such as the Samsung 990 Pro is a sensible upgrade for your whole library, but it is not a requirement for this game.
