A DirectX 12 hook implementation using ImGui and Kiero. This project allows you to inject custom ImGui interfaces into DirectX 12 applications.

Features

• DirectX 12 Hook implementation
• ImGui integration through Kiero
• Resizable window support
• Fullscreen support
• Minimal performance impact
• Doesn't crash when injected instantly (before window is created)

Requirements

• Windows 10/11
• Visual Studio 2022
• DirectX SDK
• CMake 3.15 or higher
• Git
