Pen lag has massively improved in OS 27. The stabilization is terrible without smoothing.
I do use an iPad Pro to animate with, i guess I’m not understanding why he Apple Pencil goes form the great asset it is on the iPad to the performance of an MPP pen when connected to a Mac.
The single-user app-dedicated iPadOS design uses a very different internal system architecture than does the multi-user multi-processing macOS architecture, and device responsiveness is part of that.
The compromises made in every operating system design can go in different directions here.
Log some feedback with Apple.
FWIW, having done a whole lot of hardware-level interface work, interrupt responsiveness of a multiuser system always lags that of a dedicated or embedded system that has I/O-designated resources. In a multiuser system of my acquaintance, we ended up designating cores and bus paths to specific interface activities to get decent I/O performance, taking those cores and those bus connections out of general use. This in addition to the cores and firmware in the external hardware involved. It wasn’t a simple undertaking.
