That is not true. Back when the game came out, they did hack the game to find that poise was multiplied by a constant that was set to 0, and that making it equal to 1, the effects of poise became visible. So they spread it on the internet that poise was turned off. Then, after more research, they discovered that this constant changed depending on what you're doing in game. If you are just standing or moving, it is equal to 0. If you are attacking, however, it becomes a constant that depends on the weapon you're using. Poise does work, it just does not work how it worked on DS1.
