I posted this as a reply to a comment here but I felt it would be better to ask as a separate comment -
Does anyone (especially from MS) know why later versions of IE and pre-chromium Edge were so good and snappy with scrolling? The level of accuracy and speed was incredible (on touchpads at least) - it was probably the last time I had an interaction on a computer that made me go "wow".
I agree the input lag and scroll curves in later IE was some of the best I’ve seen. Firefox was as good for a time but is now (slightly) worse after changing to a more chrome-like curve
They really went all out on input lag reduction for Windows 8 touch interfaces. I remember some videos from the time where they showed off such low input lag that scrolling and drawing almost perfectly tracked finger movement. Perhaps not so impressive today with iOS as a benchmark, but Windows is still king for desktop input lag
