Hardware Oscilloscope Latency Test: 400 DPI vs 1600 DPI vs 3200 DPI
By hooking up a high-precision rotary encoder and digital oscilloscope to an automated test rig, we measured the exact millisecond delay between physical displacement and the first USB packet broadcast.
Test Results Summary
At slow micro-adjustment speeds (5 cm/s):
- 400 DPI: 12.7 ms delay to register first count.
- 800 DPI: 6.3 ms delay.
- 1600 DPI: 3.1 ms delay.
- 3200 DPI: 1.6 ms delay.
Conclusion: Raising your hardware DPI to 1600 or 3200 DPI cuts initial motion latency by more than 9 milliseconds.
