A Windows gaming companion. Beta 1.1 — 0.1.0-beta.1.1.
Serein shows what your PC is doing and lets you temporarily manage selected background apps while you play. It also helps you understand your hardware and find official driver support. There is no promised FPS increase: results depend on your PC, game and background workload.
- Open Releases.
- Download Serein-0.1.0-beta.1.1-win-x64.zip under Assets. The source-code archives are for people who want to build the app themselves.
- Extract the whole ZIP into a folder. Keep its files together.
- Open Serein.Gaming.WinUI.exe. No separate .NET installation is needed.
This beta has been tested on Windows 11, 64-bit. Windows 10 support is a target, but has not been validated. The app is unsigned, so Windows may show an unknown publisher warning. The release includes a SHA-256 checksum for checking your download.

New in Beta 1.1: choose installed games from Steam, Epic Games and GOG, with search and store filters. You can still choose your own EXE. If a game has several EXEs, confirm the actual game process.
- Watch your PC: live CPU, GPU and memory activity, charts, disk and network throughput. Unsupported sensors show an unavailable value.
- Set up a gaming session: choose a game and background apps you allow Serein to manage. Gaming lowers their priority; Extreme temporarily freezes them.
- Restore changes: use Restore all, or let the session restore its changes after the game exits or the timer expires. A separate watchdog handles controller failure; recovery still has limitations described below.
- Manage an app manually: search the process list and apply a temporary action to an eligible app. Windows, games, launchers and protected dependencies are excluded.
- Understand devices: installed drivers, manufacturers and hardware details. SSD firmware is shown separately from the Windows driver.
- Look for drivers: explicitly search Windows Update or open relevant official manufacturer support. A support link does not prove a compatible update exists.
- Make it yours: themes, accents, panel shapes, text size, dashboard blocks, image backgrounds and optional animated glass patterns.
- Choose a language: English is the default; Russian and German are included. Change it in Settings → App language. Changes apply immediately.
This is Beta 1.1, not a finished production release. Bugs and missing features are expected. Start with monitoring, then try gaming actions only on apps you can safely pause. Freezing stops downloads and file saves and can hold shared resources. Restoration is tested but cannot cover every crash or Windows failure.
Driver discovery does not install anything. Installation opens Windows Settings for your own selection. Windows Update does not cover every manufacturer; an empty result does not mean all drivers are newest. Device recognition has a limited curated catalog. Serein does not install SSD firmware.
AMD GPU sensors use an existing supported AMD driver. CPU temperature needs the separate supported AMD monitoring component and an explicit administrator-approved connection. Vendor components are not bundled. Other hardware may have fewer readings.
This download uses WinUI 3. Tray, cleanup, startup/service tools, integrated FPS capture and the complete driver installer have not yet been moved into this interface. Older WPF source is included for development; its wider feature set is not what this download ships.
Suggestions for improvements and new features are very welcome. You do not need to be a developer. Open an issue and explain what you would like to do, or what went wrong. Screenshots help; remove personal paths, serial numbers and other private information first.
Code fixes, translations and hardware-recognition improvements are welcome too. See CONTRIBUTING.md.
You need .NET 10 SDK, Windows SDK and Visual Studio's Windows/WinUI build tools.
The build is for Windows x64 and uses the SDK version in global.json.
In PowerShell, from this repository's folder:
powershell -NoProfile -File experiments/Serein.Gaming.WinUI/build.ps1 -TestThe app is written to artifacts/Serein-Gaming-WinUI/. Tests use mocks and their
own helper apps; they do not install drivers or tune unrelated desktop apps.
