Your comment” My first non-linear editor, a very simple program called D/Vision Pro, was actually far better at off-line editing than Resolve. Oh, when was that? A couple of decades ago? And with a very basic computer, by today’s standards” is very strange.
Decades ago you’d have been working with lower resolution video, possibly at lower framerates, very unlikely to have been using VFX/motion graphics etc.
It’s not at all a useful comparison.
