[Strokes should not auto smooth as default]

Hi, i'm having the same problem i think. I set the brush and the controller to: Pressure, and even tried the controler: Brush Defaults... but i draw a line with my cintiq and it preview exactly the line i want, and when i let go it becames finner or changes in a way that i never know what to expect. Do you have a tutorial on how to customize the pressure so it is more acurate? Like in the ilustrator i set the brush and chose the variation, and in the affinity i think it was the same but it's not working! And this is a big thing guys!!! Please help! tks
