CHAPTER 2 · ENGINE DESIGN 03 / 12

How precision becomes instinct

1
The frame is the truth
16ms step windows verified at 60fps on every cabinet, home pad, and mobile build we ship.
2
Arrows arrive on time
Adaptive chart streaming syncs to the millisecond. A 4G blip never costs a combo.
3
The floor talks back
Stage LEDs mirror game state with zero perceptible lag from footfall to glow.
4
Every set is replayable
Full-session capture in 4K, with per-step timing heatmaps you can study or share.
