How I Built a Fast 2D Renderer (Sprite Batching)
In this video I break down how I built a high-performance 2D renderer capable of rendering thousands of sprites efficiently by batching textures and minimizing draw calls, a core technique used in modern game engines. I explain how dynamic batching, and GPU-friendly data layouts allow you to drastically reduce state changes and CPU overhead while keeping the renderer simple and scalable. If you are building your own 2D game engine or custom renderer and want to understand how professional engines achieve fast sprite rendering, this video shows a practical, engine-level approach to sprite batching, texture management, and efficient rendering architecture for real-time 2D graphics.
