After O3DE’s 18 ms frame-graph readback made 30 FPS streaming impossible, we tried Godot. It got us there — eventually. This is the full path from 105 FPS on nothing to 50 FPS per camera with three live RTP streams, including every wrong turn and every underdocumented Godot behavior we hit on the way.
Exploring whether O3DE can replace Unity as the render engine for a drone simulation that streams multiple 1080p camera feeds via GStreamer. From first scaffold to three live RenderToTexture pipelines in a single session.
A detailed technical walkthrough of profiling and optimizing a headless Unity simulation from 21 to 25 FPS — covering NVENC GPU encoding, batch camera rendering, GPU instancing, static batching, and the failed URP migration. Every measurement, every dead end, every lesson.
How I replaced flat brown terrain and solid-color sky in a headless Unity 6 Docker simulation with real satellite imagery, SRTM topography, and a custom panoramic skybox — all fully air-gapped, no runtime network dependency. Includes NVENC GPU encoding, custom shaders, and every dead end along the way.
A detailed technical account of containerizing a Unity 2019.4 drone simulation with GPU-accelerated rendering, dual RTSP camera streaming via FFmpeg/mediamtx, and MAVLink drone control — including every obstacle encountered and how it was solved.
