Undertale: PC System Requirements & Best Hardware to Run It (2026)

Undertale is one of the least demanding PC games you can play in 2026. Built with GameMaker and using retro-style 2D pixel graphics, it will run well on virtually any modern desktop or laptop, including budget office PCs, older integrated graphics, and handhelds. If your PC was made in the last 10 years and runs Windows 10 or Windows 11, you already have more than enough power for a smooth 60 FPS experience at any resolution. You do not need a dedicated graphics card, a gaming CPU, or more than a few gigabytes of RAM.

Undertale PC Requirements: Minimum and Recommended Specs

Undertale pc requirements are extremely low compared to modern AAA titles. The developer Toby Fox lists only a very modest minimum spec on the publisher’s store page, and there is no separate official recommended spec. The table below is approximate, based on the publisher’s store page, with a practical recommendation for a smooth experience on modern systems.

All figures above are approximate, based on the publisher’s store page on Steam. Undertale does not publish a demanding recommended spec because the minimum spec itself is enough for the full game. If you meet the minimum, you will get the intended experience. There is no need to chase higher specs for this specific game, and storage requirements have not changed since launch.

How Demanding Is Undertale Really?

Unlike modern 3D games, Undertale does not use complex shaders, high-resolution textures, ray tracing, or large open worlds that need to be streamed from storage. It is a 2D sprite-based RPG with a fixed resolution and simple effects, designed to run at 30 to 60 FPS even on very old hardware.

In practical terms, this means the GPU is almost never the bottleneck. Even basic integrated graphics from 2014 onwards can render the game at hundreds of frames per per second if uncapped. The CPU load is also minimal. There is no heavy physics simulation, AI crowd, or procedural world generation. RAM usage stays well under 1 GB during gameplay, and the entire game is smaller than a single high-resolution texture pack for a modern shooter.

Because the requirements are so low, performance testing from outlets like TechPowerUp, Tom’s Hardware, and TechSpot does not specifically benchmark Undertale on modern GPUs. There is no meaningful difference to measure between a budget and a high-end card. Approximate ranges from public outlet testing of similar 2D GameMaker titles show that any integrated GPU from the last decade delivers well over 60 FPS at 1080p, often in the 200-500 FPS range if frame rate is uncapped, while power draw stays under 15W.

You should think of Undertale as a game that runs on the class of hardware, not a specific hardware tier. If your PC can browse the web and play YouTube videos smoothly, it can play Undertale.

GPU Recommendations by Resolution: What to Expect

You do not need to buy a GPU for Undertale alone, but if you are building or buying a PC and want to know what to expect at different resolutions, here is a general guide. All expectations are for a locked 60 FPS, which is the game’s intended cap.

1080p (Full HD)

At 1080p, any integrated graphics will do. Intel UHD Graphics 620, Intel UHD 730 / 770, Intel Iris Xe, AMD Vega 3 / Vega 6 / Vega 8, and AMD Radeon 610M / 780M all run Undertale flawlessly at 60 FPS with headroom to spare. If you have a dedicated card like an NVIDIA GeForce GTX 750 Ti, GTX 1050, RTX 3050, or any AMD Radeon RX 460 and newer, the game will be completely effortless. Public testing of lightweight 2D games on these iGPUs typically shows approximate ranges of 120-300+ FPS uncapped at 1080p.

1440p (QHD)

1440p does not meaningfully change the load for a 2D pixel game. The same integrated graphics listed above still deliver a locked 60 FPS without drops. There is no high-resolution texture cost, so VRAM usage remains under 300 MB. A dedicated GPU offers no visible benefit for Undertale at this resolution. If you use a 1440p monitor for work or other games, Undertale will scale cleanly with black bars or stretched pixels depending on your display settings.

4K (Ultra HD)

Even at 4K, Undertale remains trivial to run. The game’s native resolution is low and it is upscaled to fit your display, so rendering cost barely increases. Integrated graphics from the last 5-6 years can still hold 60 FPS at 4K. Dedicated GPUs are overkill. The only consideration at 4K is integer scaling if you want perfectly sharp pixels. This is a display setting, not a performance issue, and has no impact on frame rate on modern hardware.

In short, for Undertale alone, do not base a GPU purchase on resolution. Choose your GPU based on the other games you play. Undertale will run perfectly on whatever you choose.

CPU, RAM and Storage Notes That Actually Matter for Undertale

CPU

Undertale is not CPU-bound. Any dual-core processor at 2.0 GHz or faster is sufficient. This includes old budget CPUs like the Intel Celeron, Pentium, Core i3, and AMD A-series or Athlon chips. Modern CPUs like the Intel Core i3-12100, Core i5-12400, Core i5-14400, AMD Ryzen 5 5600G, or Ryzen 5 7600 are vastly more powerful than needed and will sit at 1-5% utilization. You will not see higher FPS from a faster CPU because the game is already capped and easily reaches that cap. Background tasks, streaming, or Discord will not affect Undertale performance on a modern system.

RAM

The official requirement is 3 GB, but 4 GB is the practical minimum for Windows 10 or 11 itself. Undertale uses very little RAM on its own, typically 200-500 MB. There is no benefit to having 16 GB or 32 GB for this game specifically, though 8 GB or more is recommended for general use in 2026 so Windows can run comfortably alongside a browser and other apps. Dual-channel RAM or high RAM speed makes no difference here.

Storage

Undertale needs only 200 MB of free space. It will run from a hard drive, SATA SSD, or NVMe SSD with no difference in frame rate. An SSD will make the initial launch slightly faster, but load times between rooms are near-instant on any drive because the assets are so small. There are no open-world streaming issues, texture pop-in, or shader compilation stutter to worry about. Mods and fan content like Undertale Yellow or Deltarune chapters also remain very small and do not change storage requirements meaningfully.

Example Builds for Undertale in 2026 (General Price Ranges)

Since almost any PC can run Undertale, these builds are not Undertale-specific but show what kind of general-purpose PC will handle it perfectly, plus other tasks.

Budget / Office-Level PC (General Range: $250 – $450 for a new system, much less used)

This class is more than enough for Undertale at 60 FPS at any resolution. Think of a refurbished office desktop or a budget laptop with an Intel Core i3-10100 / i3-12100, Intel N100, AMD Ryzen 3 3200G / Ryzen 5 5600G, 8 GB RAM, integrated graphics, and a 256 GB SATA or NVMe SSD. No dedicated GPU is needed. This level will also handle web browsing, office work, indie games, and emulation up to the PS1 era without issues.

Mainstream 1080p Gaming PC (General Range: $600 – $900 for a new system)

If you also play modern games, a mainstream build like an Intel Core i5-12400 / i5-14400 or AMD Ryzen 5 5600 / Ryzen 5 7600, 16 GB RAM, a 512 GB NVMe SSD, and a GPU such as an NVIDIA GeForce GTX 1660, RTX 3050 / RTX 4060, or AMD Radeon RX 6600 / RX 7600 is a balanced choice. For Undertale, this hardware will be essentially idle. The benefit here is for AAA games, where such a system can deliver approximate ranges of 60-100 FPS at 1080p high settings according to public testing from Hardware Unboxed and Gamers Nexus, while Undertale will remain locked at 60 FPS with minimal power usage.

You do not need a build stronger than this for Undertale. A high-end gaming PC with an RTX 4070, RTX 4070 Super, RX 7800 XT or better offers no advantage for this title.

Laptop and Handheld Suitability: Steam Deck, ROG Ally and More

Undertale is an excellent fit for laptops and handhelds, and is a great game for portable play.

Laptops: Any Windows laptop from the last 8-10 years with integrated graphics will run it perfectly, with silent fans and long battery life. Even thin-and-light laptops, Chromebooks running Windows via dual-boot, and budget school laptops hold 60 FPS. Battery drain is minimal, often under 10W total system power.

Steam Deck: Undertale is Verified on Steam Deck and runs flawlessly on both the LCD and OLED models. It holds a locked 60 FPS at the Deck’s native 1280×800, with very low power draw and around 6-8 hours of battery life in testing. Controls work with the built-in gamepad, and the text is readable on the 7-inch screen. No settings changes are needed.

ROG Ally, Legion Go, MSI Claw and similar: All Windows-based handhelds run Undertale without issue at native resolution. Like the Steam Deck, they will deliver a locked 60 FPS at minimal power. You can comfortably play on battery at a low TDP limit (e.g., 10-15W) for extended sessions.

Older handhelds and low-power tablets: Because the game is so light, even devices like the GPD Win, older Surface tablets with Intel Atom or Core m3 chips, and budget handheld PCs can play it well.

Settings That Actually Raise FPS in Undertale

Undertale has very few graphics settings, and most systems will not need to tweak anything. If you do experience frame drops, which is usually due to vsync or background software rather than hardware power, these options help:

• Run in Fullscreen vs. Borderless Window: Fullscreen can reduce input lag slightly on some systems, while borderless windowed is more stable for alt-tabbing. If you see tearing or stutter, try toggling between them. Undertale’s performance is identical in both modes on modern Windows, but vsync behavior can differ.
• Enable vs. Disable VSync: Undertale is designed around 60 FPS. If you have screen tearing, enable VSync in your GPU control panel. If you have stutter on a high-refresh monitor (144 Hz / 240 Hz), try forcing VSync off or setting the display to 60 Hz while playing. This is the single most effective fix for perceived choppiness.
• Disable Unnecessary Background Apps: On very old PCs with 3-4 GB RAM, closing a browser with many tabs can free up RAM and CPU cycles. Undertale itself will not max out your system, but Windows can feel sluggish if RAM is full. This helps maintain a consistent frame time more than raising average FPS.
• Use Your GPU Control Panel for Integer Scaling (4K): For sharper pixels at 4K, enable Integer Scaling in Intel Graphics Command Center, NVIDIA Control Panel, or AMD Adrenalin. This does not raise FPS, but it improves image clarity with no performance cost and is the best visual tweak for high-resolution displays.

There are no texture quality, shadow, or anti-aliasing settings to lower in Undertale. If the game still does not reach 60 FPS on a modern PC, check for Windows Game Mode, outdated graphics drivers, or a forced frame rate limit in your GPU software rather than upgrading hardware.

Frequently Asked Questions

Can I run Undertale without a graphics card?

Yes. Undertale runs perfectly on integrated graphics alone. You do not need a dedicated NVIDIA or AMD graphics card. Intel UHD, Iris Xe, and AMD Radeon integrated graphics are all more than enough for 60 FPS at 1080p, 1440p, and 4K.

How much RAM do I really need for Undertale?

The game itself needs less than 1 GB, but you should have 4 GB minimum for Windows and 8 GB for comfortable general use in 2026. More than 8 GB does not improve Undertale performance.

Does Undertale run on Steam Deck and at what frame rate?

Yes, it is Steam Deck Verified. It runs at a locked 60 FPS on Steam Deck, ROG Ally, Legion Go, and similar handhelds, with very low battery drain.

Do I need an SSD for Undertale?

No. An SSD makes Windows and game launches faster, but Undertale loads instantly even on a hard drive. Any storage type works, and the game only needs 200 MB.
