# Optimize Three.js Games
Measure before changing behavior, then validate the same gameplay path after every optimization.
## Establish a repeatable scene
Choose a deterministic representative encounter and record device, viewport, quality level, player position, enemies, active effects, frame-time sample, draw calls, triangles, texture count, and warnings. Compare like with like.
## Diagnose the limiting side
- Suspect CPU when simulation, allocations, React work, pathfinding, or per-frame scans grow with actors.
- Suspect GPU when resolution, overdraw, shadows, transparent particles, post-processing, draw calls, geometry, or texture bandwidth dominate.
- Inspect before optimizing; do not lower quality blindly.
