We had the pleasure of presenting at DevFest Nantes 2025 our experience on optimizing legacy web user interfaces in an AAA game engine.
Context
Some AAA game engines use web interfaces (HTML/CSS/JavaScript) for their menus and cockpits. These interfaces, often inherited from previous versions, must run at a constant 60 FPS in a context where every millisecond counts.
