Cant change graphic quality

i have a problem, everytime i change the graphic quality to fastest, it always turn back to fantastic, and my laptop is not that best to play on fantastic. Always it changes to fantastic when i start the game (in the launcher)

Thank you for comments!

Change the slider in the options menu instead

So the slider ingame in the options menu? Alright i will try

Nope, still lagging. Can i do something for it? I cant play the game and i payed 18,99€ <.<
