Reduce draw calls by batching sprites\/meshes that share a material, packing textures into atlases so fewer bind calls happen, sorting the render queue by texture\/shader before draw order, and avoiding per-object uniform or texture switches inside the render loop.<\/strong><\/p>\n

Draw calls and texture binds are expensive because each one is a round trip between your JavaScript\/engine code and the GPU driver. The fix is almost always the same: group objects that share a material and texture, and submit them in one call instead of many.<\/p>\n
