Senior C++ Developer for MMORPG Overlay

@appmechanic

Hello, I hope you're having a great day. I bring hands-on C++ work for Windows desktop applications, having delivered multiple projects that focus on low-latency rendering and responsive UI using modern C++ (C++20) and Win32 foundations. I built a lightweight overlay for a video-conferencing tool that needed sub-16ms frame updates, DirectX 11 rendering, and ImGui-driven controls, solving stutter caused by threading contention and synchronizing per-frame state from an external process. I'd usually start by profiling the target game's process interaction, then scaffold a small prototype with DirectX11 + ImGui to validate render timing and input hooks, and add a worker-thread design for game-state parsing to keep UI responsive. If you have ten minutes, I'd like to compare notes on how you expect game state to be exposed and what update cadence you need. I have some questions regarding the project: 1. Should the overlay read memory, use an IPC stream, or accept telemetry from a plugin? 2. Do you prefer DirectX11 or DirectX12 as the primary renderer for compatibility? 3. What hotkey handling model do you want (global hooks or in-process shortcuts)? Thank you, Paramjot Singh

I can help with this, Hi, I will build your MMORPG companion overlay using C++20, ImGui, and DirectX 11/12, delivering a transparent, hotkey driven UI that reads live game state and surfaces intelligent recommendations with minimal frame impact. On a similar real time overlay project, keeping the render loop on a dedicated thread and batching ImGui draw calls kept CPU overhead under 2% even during heavy combat scenarios. I will architect yours the same way. Questions: 1) Are you hooking into the game's rendering pipeline directly (e.g., swapchain present hook) or running as a standalone transparent window on top? 2) Will the JSON configuration system need cloud sync for profile management, or is local storage sufficient for launch? Looking forward to your response. Best regards, Kamran
