Hello...

I can´´t Play the game with my Gamepad, it´s not recognized by the game. The calibration was fine but during the game nothing happend with the pad.

greetings reef

same problem...

bought pad today specialy for Witcher and at Windows it works.
But Witcher3 does not know my PS4 pad.
Is there someting i have to do? Some spechial Butons to push?

(Using it with USB-cable)

I've got the same problem with my xbox 360 gamepad. The game only detects mouse+keyboard

DS4-Tools are said to emulate XBox Input.

I know this might sound obvious but have you tried the controller in any other game so you can confirm it's a problem with the Witcher.
If you have done the above try re-installing the driver for your controller, make sure you have the latest driver

Take look at that :)

FOUND ANOTHER SOLUTION FOR THE PROBLEM WITH GENERIC CONTROLLERS.
HAVE A GENERIC X360 THAT DIDN'T WORKED, JUST RESTARTED MY PC WITH THE CONTROLLER PLUGGED IN (IT WILL RECOGNIZE AS FIRST CONTROLLER), THEN STARTED THE WITCHER AAAAAAND (HERE IS THE REAL THING) STARTED THE NEW GAME. AS I STARTED MOVING GERALT AROUND, THE CONTROLLER WORKED PERFECTLY.
