Input Devices: Polling, Wireless, and Why Consistency Beats Specs
Most “input problems” are not the mouse or controller. They are inconsistent timing: unstable polling delivery, wireless noise, or system load that changes day-to-day.
Baseline (Stability First)
- Use one device path and keep it stable (same port/dongle).
- Avoid stacked software layers while testing (one driver layer).
- Pick a polling rate you can keep stable under load.
- Remove background CPU spikes before judging feel.
- Retest the same scene/map to judge consistency.
Common Mistakes
- Chasing max polling while frametimes are unstable.
- Switching between USB ports or hubs and blaming the device.
- Testing wireless in a noisy environment without moving the dongle.
Rule: if your aim feels different day-to-day, suspect timing and stability before buying new hardware.
