Optimizing CPU-side Rendering Code
Summary
The article details CPU-side rendering optimizations in the Godot engine, including a structured profiling workflow with tools like Tracy and Superluminal, and concrete improvements such as updating existing meshes instead of recreating them. It presents two case studies—Polygon2D optimization and SPIRV to DXIL transpilation—highlighting measurement, testing, and tradeoffs between CPU and GPU workloads to achieve significant FPS gains.
