Babylon Native perf report

Cross-engine comparison. Lower is better for every metric.

Frame budget per asset: 1000 warmup frames (untimed for stats) + 2000 timed frames = 3000 frames total, identical for every .glb and .js.
Avg / Min / Max in the table are computed over the 2000 timed frames only; warmup is excluded.
Each Avg / frame cell shows avg ms (min - max); comparison engines appear in small text below with the same triple plus a percentage delta (green = displayed engine is faster, red = slower).
Click ▶ Graph on a row for an inline per-frame timing curve (all 3000 frames; warmup region shaded).
