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].

      I never had an issue on hollow knight. Both on PC Linux and steamdeck. […]

      I’m not sure what the exact replication bounds are for the bug; maybe your configuration simply doesn’t experience the issue? Or perhaps you inadvertently configured Steam to force proton somewhere?

        Actually, I remembered that on PC at least (arch btw) it wouldn’t even launch natively, so I forced proton.
