 Godot gives you one `Skeleton3D` per character. Want 200 animals in a herd? That's 200 skeleton nodes, 200 draw calls, and 200 `AnimationPlayer` ticks every frame. Want 1,000? Now you're measuring in seconds per frame, not frames per second.
 
-We built a GPU skinned-instance renderer into Tinqs Engine that packs every pose into a single texture, uploads once, and draws every instance in one call. 25 crocodiles on screen right now. 1,000+ projected. Same bone count, same animation fidelity — a tiny fraction of the cost.
+We built a GPU skinned-instance renderer into Tinqs Engine that packs every pose into a single texture, uploads once, and draws every instance in one call. 25 crocodiles confirmed first. Then we threw 1,000 animals — 12 types mixed, random-walking — at it and the GPU didn't flinch. Same bone count, same animation fidelity, a tiny fraction of the cost.
 
 ## Why the engine needs to change

 In [Ariki](https://www.arikigame.com), the sim tracks animal migration across a 12km archipelago. `AnimalHerdRenderer.cs` groups sim `ViewerState.animals` by type, feeds positions to `skinned_herd.gd` (a reusable per-type herd backend), which drives the renderer. One `AnimationPlayer` animates a single driver skeleton; poses propagate to every instance.
 
-The crocodile herd scene is 25 instances, one draw call. The same pipeline projects to 200–1,000 before the GPU budget even notices.
+The crocodile herd scene was 25 instances, one draw call. The perf test scene does 1,000 animals across 12 types — Boar, Cow, Crab, Crocodile, Deer, Fish, Goat, Hen, Pig, Rabbit, Sheep, Tiger — each type its own GPU herd, all mixed, all random-walking, FPS holding steady.
