No pen pressure in Photoshop without "ink" in wacom settings.

The Ink option make may pen slow an lagging,  win10 sometimes shows annoying ripples and circles , I had trembling cursors  etc.     Get rid of ink years ago and never had an issue.  So not sure why Photoshop  needs it really .   I recall there were some hack to make it work with  older option.  But I can't recollect what it was .  Would be appreciated if anyone know and could tell.
