System requirements

Quick answer

Steam currently attaches no Windows, macOS or Linux requirements to I Have Known You. The store lists all three platforms, but the requirements panels are empty — normal for an unreleased app whose build is still changing.

The system requirements panels on the I Have Known You store page are empty. Not vague — empty. Steam lists the game for Windows, macOS and Linux, but attaches no minimum or recommended hardware to any of the three.

What the store page currently shows

Platform	Minimum	Recommended
Windows	Not listed	Not listed
macOS	Not listed	Not listed
Linux	Not listed	Not listed

That is not unusual for an unreleased title. Requirements are usually filled in when the build is locked and the developer has tested a range of machines, which for a February 2027 release means late 2026 at the earliest.

Why the panels are empty

Three plausible reasons, all normal:

The build is still changing. A visual novel's requirements are mostly about video playback and resolution. Until the art pipeline is final, numbers would be guesses.
The demo is the test. A studio with a live demo can point at it instead of publishing specs: if the demo runs, the full game will run.
Store pages are filled in stages. Price, requirements and languages are often finalised together, shortly before launch.

The practical upshot is the same: use the demo as your compatibility test.

What this genre actually needs

A story-driven visual novel is not a demanding genre. The load is images, audio and text, not 3D rendering or physics. Across the genre, the pattern is consistent:

Component	What matters	Why
Storage	A few GB	Full-screen art, voice or music, and the script
RAM	Modest	Mostly asset streaming and the script engine
GPU	Anything recent	2D art at 1080p or above
Display	1080p or better	Text-heavy interface; small text is the real constraint
Input	Mouse or trackpad	Visual novels are click-driven, with keyboard shortcuts

Those are genre expectations, not numbers published by this developer. Treat them as a sanity check rather than a specification.

How to test your machine before February

The demo is the cheapest compatibility test available, and it costs nothing.

Install the demo and play for twenty minutes, including one free-roam section.
Open the character screen and scroll the roster. That screen is the densest interface in the game.
Turn the resolution up to your monitor's native setting and check that the text stays crisp.
Try your default window mode. If you play windowed, check that the dialogue box and quick menu stay readable.

If the demo runs smoothly at your resolution, the full game almost certainly will. If it does not, the requirement panels being empty is your signal to wait for published specs rather than assume.

Resolution and text size

The interface in the demo is built around a dialogue box, a quick menu with seven controls, and a character screen with a list and a dossier. All three are text-dense, which means the practical requirement is not GPU power but screen size and eyesight.

Setup	What to expect
1080p monitor	Comfortable; interface designed around it
1440p or 4K	Sharper art; check whether the interface scales
Laptop 1366×768	Workable, but the dossier text gets dense
Steam Deck	Verify text size before committing to a long session

Steam Deck and handhelds

Steam does not list Deck compatibility for the app yet, and the requirements panels being empty means there is no official statement either way. A 2D visual novel with click controls is usually a good fit for a handheld, but "usually" is not a promise, and the character screen is the part to check first.

What to do if your machine is marginal

Play the demo at a lower resolution first. If the text is legible, the game is playable.
Prefer a desktop or laptop with a discrete GPU if you plan to play at 4K; integrated graphics handle 1080p 2D art comfortably.
Keep an eye on the store page. Requirements panels are usually filled in a few months before release, and this one has until February 2027.

For the release facts, read release date and platforms. For the interface you will actually be reading, read controls and settings.

Mac and Linux notes

All three platforms are listed, which is a stronger commitment than a "coming to PC" line. Two practical points follow.

Apple Silicon. The store page does not state whether the macOS build is native or translated. If you are on an M-series machine, the demo is the test: install it and check whether the game runs natively in Activity Monitor rather than under Rosetta.

Linux. A native Linux listing usually means a build the developer intends to support, not a Proton-only note. The demo is the fastest way to confirm it launches on your distribution.

Steam Deck. Steam does not list Deck compatibility for the app, and the empty requirements panels mean there is no official statement either way. A 2D visual novel with click controls is usually a good fit, but the dossier screen is text-dense, so check legibility before planning a long session.

The absence of requirement data was checked against the official Steam app data for 3944610 on 3 November 2026; the genre expectations are labelled as such and are not developer specifications.
