Learn how controllers really work
Short, honest explainers that go straight from a question to a test you can run in your browser. Where numbers appear they come from our published measurement dataset — not from a marketing page.
What Is Stick Drift?
A controller stick moves or aims on its own, even when untouched. Learn what the drift percentage means and when it is worth fixing vs tuning around.
Read guide →Controller Deadzone Explained
A deadzone is the region of stick travel a game ignores. Here is how inner vs outer deadzones work and how to set them without guesswork.
Read guide →Gamepad Polling Rate (Hz)
How often your controller reports its state to your device. 125Hz vs 250Hz vs 1000Hz — what changes in feel, and what does not.
Read guide →Controller Input Latency
Where the delay in input → pixels actually lives, and the part a controller can and cannot control.
Read guide →Hall-Effect vs Potentiometer Sticks
The two dominant stick sensors, and what our 140,000+ measurement dataset shows about how they age.

Sticks, triggers, buttons and the digital report your device actually receives — the 10-minute mental model.

None of this matters if your stick already drifts. Run the Stick Drift Detector now — it takes two minutes and gives you a 0.1%-precision number to tune against.
