Pressure is always reported as 0

Rene-Damm commented on Jul 18
The Windows 7 touch API does not support pressure. I think what we ultimately want is Windows 8+ pointer API-based touch support. Unfortunately, as long as we haven't dropped Win 7 support (which likely won't be the case for quite a while), that'll mean that the touch codepath will get split in two, making it quite likely the old Win7 codepath will break more often.

Anyway, something to look into. For now, as long as we support pressure on pens, I'm not terribly concerned about not supporting pressure on touch.
