Why do all of the selection tools in Photoshop have a input lag

Why do all selection driven tools suffer from a delay on input? Marquee, lasso, patch, polygon, or any tool that creates selections, experience a significant delay when initially dragging, which is particularly noticeable with smaller scale selections. 

We know that Adobe knows about this. It’s been a problem across all platforms, hardware, and with all peripheral devices, as far back as 2020, if not prior. It is present in all file types, with all layer setups, and at any resolution. Can we stop beating around the bush and get an explanation as to why this behavior is seemingly now inherent and presumably unfixable, rather than some arbitrary aberration? 

What changes were made that caused this?

Is this the result of legacy code that is compromised by modern builds? Arbitrary driver incompatibility? What coded mechanism is the culprit here?
