Just wanted to share a problem that i had with the crosshair while drawing.
Regardless of drawing complexity my crosshair didn´t match the movement of my mouse.
Tried every listed sloution only to find out that a cheap old Logitech M90 mouse works perfect.
The problem was with the Microsoft Intellimouse.
Thanks for letting me know.
This was one of the (many) articles i read trying to fix it.
As mentioned the mouse seemed to be the problem for me, havent had the lagging crosshair yet.
