Quick answer: Windows GameInput API delivers stick values that feel sluggish around center? The API doesn’t apply a deadzone — you receive raw readings. Apply your own deadzone curve.

A racing game on Windows feels sticky when you nudge the stick slightly. GameInput returns the raw analog value with no quantization to zero near center.

Apply a Radial Deadzone

float magnitude = std::sqrt(x*x + y*y);
if (magnitude < 0.10f) { x = y = 0; }
else { float scale = (magnitude - 0.10f) / (1 - 0.10f) / magnitude; x *= scale; y *= scale; }

Radial deadzone with re-scaling so the usable range is 0..1 outside the dead area.

Sensitivity Curves

Layer a curve (e.g. cubic) over the deadzone for fine control. Players appreciate the precision near center; flat linear feels too twitchy on action games.

Per-Controller Calibration

Drift varies by controller / wear. Expose deadzone sliders in settings — old controllers may need 15-20%.

Triggers Too

Triggers have analog resting positions too. Apply a small deadzone (~5%) so a slight press doesn’t register.

Verifying

Sticks feel responsive past the dead area, dead-quiet inside it. Players don’t report drift complaints.

“GameInput is raw. Build your own deadzone + curve.”

Make deadzone player-configurable from day one — controller wear varies, and shipping a fix mid-life is much harder than shipping a slider.
