Quickly verify if your controller works with any game or platform. Our tool supports all major brands, ensuring a smooth and error-free gaming experience every time.
Detecting Hidden Hardware Degradation
Most gamers don’t realize their controller is failing until it’s too late. Software-level auto-calibration in modern consoles often ‘hides’ early stick drift or sensor jitter by expanding deadzones without your knowledge. This leads to a ‘mushy’ feel and inconsistent aim that ruins competitive gameplay.
Expert Solution
At GamepadScan, we provide the raw, unfiltered telemetry that professional eSports players use to calibrate their gear. Unlike standard testers, our system isolates the report rate and 16-bit axis resolution to ensure your hardware is physically capable of peak performance. Whether you are verifying a new Hall-Effect sensor or troubleshooting a legacy membrane button, our data-first approach removes the guesswork from your setup.
