Magpie

Magpie is a free, open-source Windows utility for enlarging windowed or fullscreen content with selectable image-processing methods. It is best suited to PC users who want to tune presentation quality and visual effects themselves. Choose it for flexible post-processing at no cost; look elsewhere if frame generation or a broader performance-optimization suite is your priority.

Overview

Magpie treats upscaling as an image-quality task rather than a way to create extra frames. It can scale either a window or the entire display, which makes it useful for games and other content that do not offer the desired native resolution or presentation. Multiple-monitor support helps it fit more complex desktop layouts, while the WinUI interface offers light and dark themes.

The project is GPLv3-licensed and downloads are provided through GitHub Releases. Its FAQ describes a non-intrusive design and says there have been no reported bans for using it, but users are still told to consider the risks of their particular games and services. Direct3D screen capture can also capture RTSS performance-monitor overlays, potentially leaving two OSD layers on screen.

Key features

• Windowed and fullscreen scaling: You can enlarge either a selected window or fullscreen content. That flexibility suits games and applications with different display modes, although it leaves the user responsible for choosing the appropriate capture and scaling arrangement.
• Several algorithms and filters: Built-in options include Anime4K, FSR and CRT shaders, among others. Anime4K and FSR address different visual priorities, while CRT shaders target a deliberately retro presentation; the range is valuable when one default look does not suit every game.
• SGSR for 3D content: The release notes describe SGSR as a lightweight upscaling algorithm designed for 3D material. It gives 3D-focused users another option without changing Magpie's emphasis on image processing.
• Composable, adjustable effects: Effects can be combined and most expose customizable parameters. Users who know HLSL can add effects, making the tool unusually adaptable for technically confident users, while newcomers may face more decisions than with a fixed preset.
• Touch and multi-display support: Touch input has been supported since version 0.11, and multiple monitors are supported. These details matter for touch-capable Windows devices and desktops where content and controls span displays.
• Screenshot hotkey: A screenshot command defaults to Alt+Shift+S, and screenshot filenames can be customized. It is a practical capture convenience, though the Direct3D overlay caveat still applies to what appears in captured content.
• No frame generation: The FAQ says frame generation is not planned because it prioritizes visual quality and considers the added latency of post-processing frame generation undesirable. Magpie therefore complements a frame-rate strategy rather than replacing one.

Pricing

Magpie is free, with a Free plan listed as free. It is an open-source Windows window upscaler, with no paid tier or trial period to evaluate. That makes it suitable for anyone who wants the full project without subscriptions or seat charges; the trade-off is that the product's value is concentrated in its scaling and effect controls rather than bundled optimization or support plans.

Platforms

Magpie runs on Windows 10 version 1903 or later and Windows 11, and requires DirectX feature level 11. It is not presented as a cross-platform application. Confirming both the Windows version and DirectX capability is essential before choosing it for an older or non-Windows device.

Who it's for

Magpie is a strong fit for Windows players and desktop users who want to improve how lower-resolution or windowed content looks, compare multiple algorithms, or build effect chains. HLSL familiarity makes the customization depth more useful, while touch support and multi-monitor handling broaden its hardware fit. It is a weaker choice for anyone specifically seeking frame generation, automated system tuning, or a tool that avoids all capture-overlay considerations.

Pros and cons

Pros

• Free and open source: The 0.00 USD plan removes subscription and trial constraints, and GPLv3 licensing permits an open project model.
• Broad visual control: Anime4K, FSR, CRT shaders, SGSR and other filters provide meaningful ways to tailor image treatment.
• Deep customization: Effects can be combined, parameters are adjustable, and HLSL users can add their own effects.
• Flexible display handling: Windowed or fullscreen scaling, multiple monitors and touch input cover varied Windows setups.

Cons

• Windows and DirectX dependency: Windows 10 version 1903 or newer, Windows 11 and DirectX feature level 11 are required, excluding other platforms and unsupported hardware.
• No frame generation roadmap: Users wanting generated frames must use another approach because Magpie deliberately focuses on scaling and post-processing.
• Overlay and game-policy caveats: RTSS overlays may be captured twice, and the non-intrusive design does not remove the need to consider risks in individual games.
• Technical tuning overhead: Combining effects and adjusting parameters offers control but demands more involvement than a single fixed scaling mode.

Alternatives

TargetFPS is a free web option when you prefer browser access rather than a Windows upscaler. FrameCoach suits users wanting a free optimizer, settings guides and a Windows desktop app. Choose Gaming Optimizer instead for a free, MIT-licensed Windows project. Hone is a Windows freemium alternative with a capped free tier, Balanced Game Mode and standard Boost-Ups, plus ads. Intel VTune Profiler is the better direction for Linux, Windows or self-hosted performance profiling. NVIDIA ShadowPlay fits Windows users with a supported GeForce setup who want the NVIDIA App. PULSE offers Windows monitoring and FPS/frametime features through free and paid options. SteelSeries Moments is another free Windows choice.

Verdict

Its main reason to choose it is the breadth of visual tuning in a free open-source package. Look elsewhere if you need frame generation, cross-platform support, or a more automated performance-optimization workflow.
