Safe troubleshooting order
- Confirm the game is using Steam Input's default configuration.
- Open Quick Access and select the intended active controller.
- Reconnect the controller, then recheck player assignment before changing in-game binds.
- Test menus and gameplay separately because focus can differ.
What the rating does not establish
Partial Controller Support and Steam Deck Playable do not publish compatibility for every third-party controller, dock or remapping layer.
Evidence boundary
Exact values, requirements and edge cases stay marked as unverified until they can be checked in the current build.
