This is because it is a software performance issue not a hardware problem - there will obviously be improvements with diminishing returns with better hardware but at the root of it is Layout.
For example - I went from a MBP with integrated graphics but with an SSD to a desktop with high-end discrete graphics and an SSD.
SU performance was transformative, Layout performance was a little better but only what you might expect from going from a 5 year old i7 to a current i7 NOT a magic bullet. Its why I have stuck on 2019 version - from experience that seems to be the most “performant” version (I have a 2020 license but don’t use it)
From what I understand Layout performance is comparable across platforms. Sluggish and problematic is an accurate description.
It goes way back - here is the mother of all threads…
