DXGI Desktop Duplication is the Windows API that Skyrant uses for screen capture. Understanding why it's undetectable requires understanding what it actually does.
What is DXGI Desktop Duplication?
It's a Microsoft API introduced in Windows 8 that allows applications to capture the desktop composition — the final rendered output of all windows. OBS Studio, Discord screen share, Windows Game Bar, NVIDIA ShadowPlay, and hundreds of other legitimate tools use the exact same API.
Why Anti-Cheats Can't Block It
Blocking DXGI Desktop Duplication would break every streaming and recording tool on Windows. Anti-cheats cannot distinguish between OBS capturing your screen for a Twitch stream and Skyrant capturing your screen for AI analysis — they use the same API calls with the same parameters.
Performance
DXGI Desktop Duplication operates at GPU level with near-zero CPU overhead. Skyrant achieves 240+ FPS capture rates without impacting game performance. The captured frames go directly to GPU memory for YOLO inference via WinML.
