I verified that my controller’s rumble worked fine, yet I had no controller rumble in Silksong. I fixed it by forcing Proton 9.0-4 in Silksong’s settings:

  1. Navigate to: Steam Library>Silksong>right-click>Properties>Compatibility
  2. Check “Force the use of a specific Steam Play compatibility tool”
  3. Select “Proton 9.0-4” from the dropdown.

It seems that Silksong has inherited the same controller rumble issue as Hollow Knight with the native build [1].

    No rumble on native version

    I enabled proton 9.0-4 (steamdeck btw), and loaded up my save and let myself take damage a couple times, still no rumble. […]

    Maybe Silksong unfortunately just has poor support for the Steamdeck at the moment. I found this which seems to support that theory:

    I’m not sure if it’s possible on the Steamdeck, but have you tried enabling Steam Input?
