Steam Input deadzone settings
If Steam presents your pad as an Xbox 360 device, you are testing Steam until you turn that layer off.
What to check first
Steam’s inner deadzone swallows the center before the game sees it. The outer deadzone reaches full deflection early. Measure twice: once with Steam closed, once with your layout on. The second number is what the game receives. The first number is the hardware.
- Close the overlay if the browser never sees the pad.
- Gyro-to-mouse will not move the stick scope unless you route gyro to a stick.
- Write both radii down before you change a slider.
Confirm the reading on the live tester before you buy parts or change firmware. The number on that page is what your browser actually receives.
A practical next step
Repeat the same test after each change and write the resting radius down. A fix that does not move that number did not fix the sensor. If the offset stays above about 0.12 with your hands off the sticks, plan a module replacement rather than another software pass. Model notes live in the controller library.
Frequently asked questions
Does this page change my controller?
No. GamepadTesters only reads the Gamepad API in your browser. Calibration writes, firmware updates, and stick swaps happen in the maker’s tool or at a repair bench.
