I don't understand this. When it is preparing shaders it has a some blurb saying this only happens on first run of the game, when you change your graphic card, or update your graphics driver. But it does this every time I start the game. On top of this there is an option to turn off preparing shaders in the graphic options, which I have done, but it still prepares shaders anyway on game start up. Is this bugged? Is this happening to everyone?
