Stick Drift, Deadzones, and Aim Assist
Aim-assist rules, deadzone scales, response curves, and input processing vary between games and can change with updates. A small browser-visible offset cannot prove when or how aim assist activates.

What the browser result means
Gamepad Test App can document repeated normalized stick-center offset and sweep coverage. It does not read a game's aim-assist state, calculate a rotational aim-assist threshold, measure electrical sigma, or recommend deliberate drift.
Safe decision path
- 1
Separate idle drift from aim behavior
First confirm whether the camera, cursor, or character moves with both sticks untouched and aim assist disabled where the game permits.
- 2
Record the game settings
Capture inner and outer deadzones, response curve, acceleration, aim-assist mode, platform, frame-rate mode, and controller profile.
- 3
Repeat the browser center check
Use a stable surface and a complete hands-off sample. Treat the result as context for the game symptom, not an aim-assist measurement.
- 4
Return to a default baseline
Restore the game's recommended defaults, then change only one setting at a time.
- 5
Use the smallest practical deadzone
Increase the affected stick deadzone only until unintended idle motion stops while deliberate small movement remains controllable.
- 6
Evaluate in the actual game
Use a repeatable practice area and the same target, distance, frame rate, and input method. Do not generalize one title's behavior to another.
Verification standard
The chosen settings should stop unintended idle movement and preserve intentional control in that specific game. Repeat after game, firmware, profile, or controller changes.
Before advanced work
Do not seek a universal zero-deadzone or drift amount to force aim assist. Such behavior is game-specific, can change, may reduce control quality, and cannot be validated by this browser tester.
Common questions
Does stick drift keep aim assist active?
There is no universal answer. Games use different activation rules, and the browser cannot observe the game aim-assist state.
Should I use zero deadzone?
Use the smallest game-specific value that avoids unintended movement and remains controllable. Zero is not automatically optimal.
Can circularity predict aim-assist strength?
No. Browser circularity depends on sweep coverage and normalization and does not measure an aim-assist system.
