It’s very unfortunate this problem isn’t addressed. The problem is not that the software cusor is bound to FPS. The problem is that it’s position is interpolated. Thats why it always laggs behind the actual hand movement, even in high FPS it’s very noticable.
We just need an option to disable interpolation on software cursors. This will make them jump to new position on low FPS but would feel much more responsive and accurate.
