Vertex initial smooth movement using the gizmo tool !?

Hi guys.
There is one thing that is always bugging me out.
In edit mode when i move a vertex using the “G” shortcut the vertex stars to move really smoothly. But when i use the gizmo to move it, there is like threshold distance to move the gizmo before the vertex starts moving and it just pops to the position where the gizmo is and this makes it a bit hard to fine tune a vertex position using the gizmo.

I am not sure if i managed to explain it well and not sure how to search for an option to “fix” this.
So anyone know how i cal deal with this - i am using a custom keys and have no the “G” shortcut available and actually do not really like to use it.

I simply would want to have smooth initial vertex movement when using the gizmo !

EDIT : actually this turns out to be related to to the case when you click and drag a vertex !

Thanks !

In User Preferences / Input you could try reducing the ‘Tweak Threshold’ value

Yeah, this is it !
Well it turns out that we can not set it to 0 but it’s better now !
Thanks !
