What its author says it does

Copied from the file, not written here

Use for PixiJS v8 performance: FPS, jank, draw calls, batching, GPU memory, destroy patterns, cacheAsTexture, GCSystem, PrepareSystem, Culler, pooling, resolution.

Use this when a PixiJS app is slow, memory-heavy, janky, or leaking resources.

Triage Order

Measure FPS, frame time, draw calls, texture memory, and object counts before changing code.
Remove per-frame allocation, Graphics.clear() redraw loops, and unnecessary texture creation.
Fix batching blockers: many base textures, filters, masks, blend-mode switches, and render groups.
Cull offscreen work only when culling cost is lower than rendering cost.
Destroy and unload resources deliberately during screen/level transitions.

Rules

Static complex vector art: consider cacheAsTexture, then turn it off before destroy if needed.
Dynamic repeated objects: pool containers/sprites; avoid creating/destroying in the hot loop.
Many simple sprites: use atlases and, when feature tradeoffs fit, ParticleContainer.
Dynamic text: prefer BitmapText or reduce text updates.
GPU upload spikes: use PrepareSystem or preload before the object appears.
Same-tab app recreation: coordinate app.destroy(...), Assets.unload(...), and releaseGlobalResources.

Common Fixes

Redrawing Graphics every frame: animate transforms or move to sprites/mesh.
Memory leak after scene swap: destroy display objects and unload assets that are no longer referenced.
Culling makes things slower: remove it for small/simple object counts.
