Thinking about playing Mouthwashing on PC and wondering what hardware you actually need? Mouthwashing is a short indie horror game released in September 2024, built around a deliberately low-fidelity, retro-styled presentation. That art direction is exactly why it runs on very modest hardware: the official requirements ask for nothing more than an older entry-level GPU, a modest processor and 3 GB of free space. This guide breaks down the official PC requirements for Mouthwashing, the best GPU for each resolution, and build recommendations that make sense for a game this light.

How Demanding Is Mouthwashing?
Not very. Mouthwashing is one of the least demanding games you can buy today. The published minimum is a GTX 560 — a card from 2011 — paired with an i5-6300HQ and 8 GB of RAM, and the recommended spec only rises to a GTX 1050 and 16 GB of RAM. In practice that means almost any gaming PC from the last decade can run it, and a modern laptop with integrated graphics can meet the recommended CPU. 1080p, 1440p and even 4K are all comfortably within reach of modest hardware, because the lo-fi art style simply does not scale into a heavy rendering load. It is also a short, linear, single-player experience with no simulation systems or large multiplayer, so it is not CPU-heavy and the processor is rarely the limiting factor. The exact published figures are reproduced below.
Mouthwashing Official PC System Requirements
| Component | Minimum (official) | Recommended (official) |
|---|---|---|
| OS | Windows 7 64-bit | Windows 7 64-bit |
| Processor | i5-6300HQ | i5-1135G7 |
| Memory | 8 GB RAM | 16 GB RAM |
| Graphics | GTX 560 | GTX 1050 |
| DirectX | Version 11 | Version 11 |
| Storage | 3 GB available space | 3 GB available space |
Source: the official Mouthwashing Steam store listing (app 2475490), checked October 2026. Publishers can update these specs after patches.
Two details are worth noting: the install is tiny at just 3 GB, and DirectX 11 is all the game asks for, with Windows 7 64-bit or newer listed for both tiers.
Best GPU for Mouthwashing by Resolution
1080p
At 1080p you are already well above what Mouthwashing needs. The official minimum — a GTX 560 — is enough to get the game running, and the recommended GTX 1050 clears 1080p without difficulty. Older cards such as an RX 560, GTX 1650 or GTX 1060 are more than sufficient. If you are buying new, an entry-level current-generation card such as the AMD Radeon RX 7600 is far beyond anything this game will ever use — it is really a card you buy for the rest of your library, not for Mouthwashing.
1440p
1440p does not change the picture much for a game this light. The same cards that handle 1080p handle 1440p, and a GTX 1050-class GPU will still run Mouthwashing at this resolution. If you want a card with genuine headroom for other games, a modern mid-range option such as the AMD Radeon RX 7600 — or a current-generation RTX 5060 or RX 9060 XT — is the sensible tier, and it leaves the game running at whatever your monitor can display.
4K
4K is more a question of your display than of the game. The low-fidelity art style does not turn into a heavy load at higher resolutions, and the NVIDIA GeForce RTX 4060 is already far beyond what Mouthwashing needs at 4K. You do not need a flagship card for this game. A current-generation RTX 5070 or RX 9070 is a fine choice if you want 4K headroom for other titles, but even older cards that comfortably beat the recommended GTX 1050 can drive Mouthwashing at 4K.
CPU, RAM and Storage for Mouthwashing
The official CPU figures — a mobile i5-6300HQ at minimum, an i5-1135G7 at recommended — tell you how little this game asks of a processor. Mouthwashing is a short, linear, single-player horror game: no simulation, no open world, no large multiplayer, so it is not CPU-heavy and almost any desktop CPU from the last decade will do. If you are building fresh, the AMD Ryzen 5 7600 is excellent value for gaming in general, the AMD Ryzen 7 7800X3D is the fastest mainstream gaming CPU if you want maximum frame rates elsewhere, and Intel fans can opt for the Intel Core i5-14600K. None of them are required for Mouthwashing specifically. For memory, 16 GB is the official recommended figure and 8 GB the minimum, so a 32 GB DDR5 kit such as the Corsair Vengeance DDR5 32GB is more than enough — just check your platform actually supports DDR5. Storage is the least of your worries: the game needs only 3 GB, and no SSD is listed in the requirements, so any drive works and load times are short either way. An NVMe drive like the Samsung 990 Pro 2TB NVMe SSD is a great system drive for everything else, but it is optional here.
Recommended PC Builds for Mouthwashing
1080p budget build: AMD Radeon RX 7600 + AMD Ryzen 5 7600 + 16 GB DDR5 — far above the official recommended spec; a GTX 1050-class card would already run the game at 1080p, so treat this as a build for your wider library.
1440p sweet-spot build: AMD Radeon RX 7600 + AMD Ryzen 7 7800X3D + 32 GB DDR5 + 2TB NVMe SSD — more than enough for 1440p in Mouthwashing, and comfortable for more demanding games.
4K high-end build: NVIDIA GeForce RTX 4060 + AMD Ryzen 7 7800X3D + 32 GB DDR5 + fast NVMe SSD — for 4K, though Mouthwashing itself is within reach of much cheaper hardware.
Is It Worth Upgrading Your PC for Mouthwashing?
Probably not on Mouthwashing’s account alone. The game asks for a GTX 560 and 8 GB of RAM at minimum, so a PC built at any point in the last decade almost certainly meets or beats the spec, and a dedicated upgrade just for this title would be money wasted. The one exception is a genuinely old machine that falls below the official minimum. If you are upgrading anyway for other games, the graphics card still delivers by far the biggest jump in gaming performance, so start there; the CPU matters much less for a game like this, and moving to 16 GB of memory is a cheap, sensible addition. Rather than replacing everything at once, target the weakest link in your build.
Can You Play Mouthwashing on a Laptop or Handheld?
Easily. The recommended processor is itself a laptop chip — an i5-1135G7 — which means a modern thin-and-light laptop with no discrete graphics card can meet the recommended CPU requirement, and integrated graphics of that class are enough for this game. Any gaming laptop from the last several years will run Mouthwashing without breaking a sweat, and battery life will be limited more by the screen than by the game. On handhelds like the Steam Deck and ROG Ally, it is a comfortable portable pick. Because it needs only 3 GB of storage, you can keep it on a microSD card or a small SSD without worrying about space.
How to Boost FPS in Mouthwashing
If frame rates are low in a game this light, the cause is usually something other than the game itself. First check that the game is actually running on your discrete GPU rather than integrated graphics, and that a laptop is plugged in and set to a performance power profile. Keep your GPU drivers up to date, close background apps, and lower your display resolution if you are on a high-refresh monitor. If you are near the minimum spec, lowering the overall quality preset or dropping resolution will ease the load further, and resolution is the most effective single change. A stable frame rate always feels better than maxed-out visuals with stutter.
Frequently Asked Questions
Can my PC run Mouthwashing?
If your PC meets the official minimum — an i5-6300HQ-class processor, 8 GB of RAM, a GTX 560-class GPU with DirectX 11 support and 3 GB of free space — it can run Mouthwashing. To match the recommended spec you want an i5-1135G7-class CPU, 16 GB of RAM and a GTX 1050-class GPU. That is a very low bar, so most PCs from the last decade qualify.
Is Mouthwashing demanding on PC?
No. It is one of the lightest games around: the minimum GPU is a GTX 560 from 2011 and the whole install is only 3 GB. Any modern budget PC, and most laptops, will run it without trouble.
What GPU do I need for Mouthwashing at 1440p 60fps?
Nothing exotic — 1440p does not change much for a game this light. A GTX 1050-class card will run Mouthwashing at 1440p, and if you want a card with headroom for other games, a AMD Radeon RX 7600-class card is a solid modern choice.
How much RAM does Mouthwashing need?
8 GB is the official minimum and 16 GB is the official recommended figure. In practice 8 GB is enough to run the game, but 16 GB is the sensible target for a modern gaming PC, since it also covers everything else you play.
Do I need an SSD for Mouthwashing?
No. The official requirements list 3 GB of available space and no SSD, so the game will run from a hard drive or a microSD card. An NVMe drive like the Samsung 990 Pro will make the game and your whole system feel snappier, but it is optional here.
