PS4 Controller Help

Can someone please help me get my PS4 controller working? I have selected use Xinput non-steam controller in the menu but it is not responding.

What am I missing?

If you want to keep a backup of your keybindings, you find then in …\My Games\Grim Dawn\Settings.

This is a fresh install. The controller is not responding at all.

PS4 controllers are D-input (or DirectInput) and NOT X-input.

To use it on Steam properly there are some guides.
