Project P.I.T.T. Steam Deck Controller Selection
Steam Deck Controller Selection: The compatibility note explicitly mentions selecting external Bluetooth/USB controllers manually.
The compatibility note explicitly mentions selecting external Bluetooth/USB controllers manually. Check the active input device before rebuilding all bindings.
Check the specific platform state
Keep the built-in controls available while testing the external device. Record whether no inputs work or only a specific action is missing.

OFFICIAL HISTORICAL · checked 2026-09-26
Valve's compatibility record lists Steam Deck Verified, native runtime and a note about manually selecting external controllers.
Build relevance: Valve compatibility test August 6, mirrored configuration checked September 26
Limit: Not a new performance benchmark of 1.0.8.
Sources: Steam app launch configuration, mirrored by SteamDB ↗
Avoid a broader claim
An official listing establishes the fields it actually publishes. It does not validate every community workaround, future feature, performance expectation or cross-platform save assumption. Keep an older compatibility test dated instead of calling it a new gameplay run.

A reversible diagnostic record
Keep the selected platform/runtime, input device and exact action together. If a change fails, return to the prior configuration and preserve the save backup; do not combine a file restore, a controller reset and a renderer change in one unexplained experiment.
