Covers destroy patterns (cacheAsTexture(false), releaseGlobalResources), GCSystem and TextureGCSystem, PrepareSystem, object pooling, batching rules, BitmapText for dynamic text, culling (Culler, CullerPlugin, cullable, cullArea), resolution/antialias tradeoffs, low-level wins (transient MSAA render textures, render bundles, partial buffer updates). Triggers on: FPS, jank, draw calls, batching, object pool, GCSystem, PrepareSystem, Culler, cacheAsTexture, memory leak, destroy patterns, render bundle, transient, MSAA, Buffer.update, WebGPU performance, TexturePool, repeatEdgePixels, bind group.

SKILL.md

Profile before optimizing. PixiJS handles a lot of content well out of the box; browser DevTools Performance + GPU profiling should be your first move. Once you've found the bottleneck, apply the targeted pattern below (destroy, pool, batch, cache, or cull).

Quick Start

container.cacheAsTexture(true);
container.updateCacheTexture();
container.cacheAsTexture(false);
container.destroy({ children: true });

import { CullerPlugin, extensions } from "pixi.js";
extensions.add(CullerPlugin);

offscreenContainer.cullable = true;
offscreenContainer.cullArea = new Rectangle(0, 0, 256, 256);
