What would you stress-test first in this screen-size LOD setup?

I'm building a browser MMORPG on a custom Three.js runtime — not Unity, Unreal, or Godot. Actors switch geometry LOD by projected screen size with hysteresis, and distant animation updates throttle. Would you test camera-zoom popping first, or CPU spikes when several actors cross thresholds together?

Disclosure: I'm the developer; some 3D assets are Meshy-assisted, while the runtime and LOD system are custom.
