Hello,
I found out what did not work and I guarantee that the problem was just about installing my graphics tablet. Not in "Artrage 5 demo"
1- In the preferences of "artrage 5 demo" I set "Input Device -> Precise Tablet"
2- I updated the drives to the Windows version - Driver 6.3.23-1 of 07/07/2017
3- Now I start the program always with the click from the graphics tablet pen: I have the idea that windows 10 puts intuos 4 in standbay and that artrage does not recognize it. It's possible?
Now all tools work without latency.
I continue to do my tests with "ArtRage 5 Demo", but I am definitely going to buy the new version of Artrage! Great new version!
Thank you,
