Crooked camera control

I don’t remember how it was in my childhood, it’s the same or normal, but now on the PC, controlling the camera with a mouse is just hell
, there is neither smoothness nor accuracy, and it feels like it’s a crooked port from the console , the mouse movement speed does not affect the camera rotation speed ,
etc.
me a pirated repack of poor quality or is it the game itself?
is there a fix?
