it worked before
recently i redownloaded game but game crashed after launch with special k
i had same issue with batman arkham knight but after downloaded latest special k issue never reproduced i guess need update for this game
I believe Far Cry 5 is one of those that makes use of EAC, and so needs it disabled before SK can even begin to work:
