As advertised in Parallels Desktop 14 (and 15) release note, the trackpad's pressure sensitivity support was introduced : Support for pressure sensitivity in Windows. You can draw in Windows apps like Microsoft PowerPoint, Leonardo or Photoshop depending on the pressure you apply to the trackpad or using a Wacom tablet connected to Mac or using apps like Astropad. https://forum.parallels.com/threads/parallels-desktop-14-for-mac-updates-summary.345229/#post-843283 In Parallels 19 and Windows 11 Pro guest on Apple Silicon, pressure doesn't seem to work. Neither does it work in Parallels 18 and Windows 7|10|11 on Intel. Where did it go ? I tried searching the forum but found no thread discussing this, only of users using Wacom which is not about trackpad.
I could confirm that the trackpad pen sensitivity actually does work (by pressing fn) on this page : Scribble Demo for Javascript (githack.com) What doesn't work is pressure in Photoshop as advertised. Anyone has a clue how to setup things so that Ink/WinTab works ?
