The Thrustmaster TH8A shifter is not explicitly listed as compatible with Forza Horizon 5 on PS5. The TH8A is generally compatible with PS5 games like DiRT 5 and WRC 9, but specific compatibility with Forza Horizon 5 is not mentioned in the available information. Forza Horizon 5 is a game typically associated with Xbox platforms, and its availability on PS5 is not standard. Therefore, it's unlikely that the TH8A would be specifically supported for this game on PS5.
