drawing line too much sensible in fresco

Hello, I have a problem which concerns the reaction time of the line between the moment when I draw with my style and the moment when the line is formed. Before there was a little time which allowed me to have less sensitivity in my line and therefore a sharper line and there the line is made at the same time as I draw so it takes into account all the tremors. I can't find the old setting, is it due to the software or my tablet? I'm lost...
