Hi Niels,
I’m reluctant to install those drivers as it says they’re for surface pro machines and also the pen works with all other software.
I have since improved things considerable by turning off “Game mode” in my huion graphics tab prefs…. I didn’t even know game mode was a thing?
Any way it is much improved however further testing has shown that the stepping still happens if I’m zoom out on the canvas but if I zoom in I can produce lovely smooth lines.
Cheers
Jim
