No change in Texture Paint Brush Sensitivity on changing Pressure Curves In Blender2.79b/Windows10-64bit,stroke's painted with mouse,using the texDraw brush(Strength = 1,Blend = Mix ) on the default DiffuseColor layer(No Alpha) work fine . 

However on switching to a pressure sensitive tablet(on latest drivers),the stroke is suddenly next to invisible.On changing the Pressure Curve  for the brush from the  Original [origin (0,0,)end(1,1)] to a New[origin (0,1),end(1,1)],the tablet stroke still remains next to invisible.  

Normally, if the software recognises the MouseStroke it means the machine's hardware is able to compute the stroke realtime but when it does not detect the pressure sensitivity of the tablet ,it does mean that the machine is not able to compute and render the Pressure sensitive stroke realtime.

On disabling pressure sensitivity by changing the PressureCurve to a Flat (0,1)(1,1) this issue is normally solved.
However in this case ,the solution is not working. 
Is there any other way to completely turnoff pressure sensitivity ?
In Blender2.79 ,Texture Paint has an "Accumulate" Option[Texture Paint Mode->Tools->texDraw brush-->Accumulate] which allows the TexDraw brush to daub strokes on top of the previous daub.This makes the brush daub thicker and hence visible.  

However,this option is "OFF" by default. By toggling it "ON" the Accumulate featured is turned "On" and a visible brush stroke is rendered (also pressure sensitivity is supported) .
