## What it is
Magpie is a lightweight, general-purpose window upscaler for Windows 10/11 that enlarges any window using GPU-based scaling algorithms. It ships with built-in effects such as Anime4K, FSR, and CRT shaders, and offers a WinUI-based interface with multi-monitor support.

## Use cases
- upscale old games that don't support high DPI
- enlarge a windowed game to fullscreen with better filtering
- apply Anime4K to anime video playback windows
- use FSR upscaling on any application window
- make low-resolution apps readable on high-resolution monitors
- scale windows with CRT shader effects

## When to choose
- you need to upscale arbitrary windows or older games on Windows 10/11
- you want GPU-accelerated algorithms like FSR or Anime4K without per-app integration
- you prefer a free, open-source alternative to paid scaling tools

## When to avoid
- you are not on Windows 10 v1903+ or Windows 11
- your GPU lacks DirectX feature level 11
- you need to upscale content on Linux or macOS
