Stella Sora’s Steam listing specifies Windows 10 or 11 in 64-bit form, at least 8 GB RAM and 20 GB of available space. Its recommended RAM is 16 GB. The older official launcher FAQ instead lists 12 GB storage and 12 GB recommended RAM, so use the specification for the client you intend to install rather than combining those figures.
Steam requirements checked October 19, 2026; mobile and original-launcher specifications from the October 19, 2025 official FAQ. These are publisher/platform declarations, not performance tests or a measured package-download size.

Steam Windows requirements
Steam listing — minimum and recommended
Scroll the table sideways on a narrow screen.
| Field | Minimum | Recommended |
|---|---|---|
| Operating system | Windows 10 / 11, 64-bit | Windows 10 / 11, 64-bit |
| Processor | Intel Core i3 | Intel Core i5 |
| RAM | 8 GB | 16 GB |
| Graphics | NVIDIA GeForce GTX 750 or above | NVIDIA GeForce GTX 1060 or above |
| DirectX | 11 | 11 |
| Available storage | 20 GB | 20 GB |
The listing names Core i3 and i5 families without a specific CPU generation. It does not provide a frame-rate target or a benchmark showing every processor in either family performs identically. The platform flags in the captured Steam response list Windows, not native macOS or Linux support; that is not a test of Proton or an emulator.
Original Windows launcher FAQ specifications
Official 2025 release FAQ — Windows launcher
Scroll the table sideways on a narrow screen.
| Field | Minimum | Recommended |
|---|---|---|
| Operating system | Windows 10 / 11, 64-bit | Windows 10 / 11, 64-bit |
| Processor | Intel Core i3 | Intel Core i5 |
| RAM | 8 GB or more | 12 GB or more |
| Graphics | NVIDIA GeForce GTX 750 or higher | NVIDIA GeForce GTX 1060 or higher |
| DirectX | DX11 | DX11 |
| Storage | 12 GB or more | 12 GB or more |
These figures are tied to the dated original-client FAQ. They do not override Steam’s later 20 GB space and 16 GB recommended-memory listing. A client replacement or later content download can require following the current download prompt; do not treat the old table as a measured size of the latest installed game.
Mobile requirements in the original release FAQ
Dated Android and iOS publisher specifications
Scroll the table sideways on a narrow screen.
| Platform | Minimum | Recommended |
|---|---|---|
| Android | Android 9.0+; Snapdragon 865+; 6 GB RAM; 12 GB storage | Android 9.0+; Snapdragon 8 Gen 2+; 12 GB RAM; 12 GB storage |
| iOS | iOS 13; iPhone 12 Pro; 6 GB RAM; 12 GB storage | iOS 18.5; iPhone 16 Pro; 8 GB RAM; 12 GB storage |
The same 2025 FAQ documents a then-existing launch problem on devices whose system language was Turkish and suggests English as a troubleshooting step. That is a dated known limitation, not a verified statement that Turkish-language devices remain unsupported in the current client.
Required space is not the package download size
Steam’s 20 GB value describes available storage, and the older FAQ’s 12 GB value is also a storage requirement. Neither figure states the compressed installer size, network transfer for a particular update or the exact final size of every installed language/resource configuration. Use the client’s displayed download and space requirements for that installation.
This page does not convert the free-space figure into a bandwidth estimate. Check both the intended drive’s free space and the download shown by the selected client before beginning.
Use the official PC download routes for the client you intend to install.
