Report Rate & Sensor Architecture

1000 Hz

Configure USB bus polling interval. Higher report rates decrease input latency for tournament gaming.

Hardware Tracking Characteristics

HERO Optical Tracking Engine Pure 1:1 hardware pixel tracking. Engineered by Logitech with zero hardware smoothing, filtering, or artificial acceleration.
1:1 Raw Active
Angle Snapping (Path Prediction) Firmware 0x2240 query: The HERO 16K/25K sensor omits artificial angle snapping to preserve pure esports accuracy.
