Asdf Overlay: High-Performance Game Overlay Library for Windows with GPU Acceleration

Asdf Overlay: A High-Performance Game Overlay Library for Windows Asdf Overlay is a cutting-edge library designed to create overlays for Windows applications, particularly games. Its standout feature is its speed and ease of use, making it a valuable tool for developers and enthusiasts alike. By leveraging GPU acceleration, Asdf Overlay efficiently hooks into various rendering backends, allowing for high-performance overlay rendering without the overhead typically associated with framebuffer copies via the CPU. Supported APIs and Features API Support: - DirectX 9/10/11 - OpenGL - Vulkan Key Features: - Multiple Backends: Asdf Overlay supports a range of graphics rendering APIs, ensuring compatibility with a wide array of games and applications. - Blazingly Fast: Thanks to its GPU-accelerated design, performance remains consistent even when rendering large or complex overlays. - GPU Accelerated Shared Overlay Surface: This feature minimizes the need for CPU intervention, leading to smoother and more responsive overlays. - Input Capture Control: Developers can manage input capture, redirecting user input to specific windows or processes as needed. Notable Uses Alspotron: - Ingame Lyrics Overlay: Enhances the gaming experience by displaying song lyrics directly within the game. Tosu: - Ingame Overlay: Provides a versatile overlay solution that can be customized for various in-game needs. Prerequisites Before using Asdf Overlay, you need to have the following tools installed: - Node.js and pnpm package manager - Nightly Rust compiler (rustc), Cargo, and MSVC (x64, x86, arm64) - Ensure that the required Rust targets (x86_64-pc-windows-msvc, i686-pc-windows-msvc, aarch64-pc-windows-msvc) are installed. Installation Node Dependencies: Navigate to the project directory and install the necessary Node.js dependencies using: pnpm install Build Asdf Overlay: Use the following command to compile the Rust components: cargo build --release Examples Node.js Example: In-Game Browser Overlay Description: When you press and hold the Left Shift key followed by 'A', an in-game browser overlay appears, capturing all subsequent user input. Pressing the key combination again closes the overlay. Demonstration: A video showcasing this functionality is available in the examples directory. Rust Example: Glitching Squares Description: This example creates glitching squares that appear and disappear on the target process or application. Demonstration: Another video illustrating this effect can also be found in the examples directory. Rust Example: Input Blocking Description: This example demonstrates how Asdf Overlay can listen to and block inputs from a target process until it exits. Demonstration: A video demonstrating input blocking is included in the examples folder. Debugging For debugging purposes, you can run Asdf Overlay with a debug build: cargo build --debug To view detailed tracing logs of the injected process, use an external debug log viewer such as DebugView. Licensing Asdf Overlay is dual-licensed under the MIT and Apache-2.0 licenses, providing developers with flexibility to choose the license that best suits their needs. In summary, Asdf Overlay is a powerful and efficient tool for creating overlays in Windows applications. Its support for multiple rendering backends, GPU acceleration, and input capture control make it an excellent choice for enhancing user experiences in games and other real-time applications. Whether you're a game developer looking to integrate advanced features or an enthusiast wanting to customize your gaming setup, Asdf Overlay offers the performance and versatility required to achieve your goals.
