This is my signature. There are many like it, but this one is mine.
Do explain exactly what you think I don’t understand?
Of the two of us Ash, one is a professional photographer who with 5 other professional photographers developed a suite of Photoshop plug-in’s, one dedicated to sharpening images (PhotoKit Sharpener). The sharpening workflow and sharpening routines were licensed BY Adobe for use IN both Lightroom and ACR. For over a decade! One of us knows what's going on under the hood in terms of this sharpening.
One of us not only reads both release notes (before installing software) and manuals, one here has worked on writing both release notes and manuals for software.
You want a primer on how LR/ACR sharpens, start at the very beginning:
As to manuals, be happy to send you the one on sharpening from PhotoKit Sharpener if you'd read it, but the introductory concept that’s important is how/where you view sharpening. Page 4 of the PKS manual discusses this and shows it:
Now there is another major difference in our posting agenda, certainly in two Adobe forums. One of us is trying to assist users with both older or newer Adobe products and has done so for many years. Another is mostly spending his time whining about a new version of one product and our posting histories are a paper trail anyone can examine. I should feel guilty hearing about your sadness and displeasure caused by the nonfulfillment of hopes and expectations from ACR but I’m struggling to do so.
It appears that Camera Raw is now applying significant sharpening with no control now at removing this. Even if we choose 'Camera Settings' for the 'Raw Defaults' we can't seem to get rid of this extra sharpening. Any ideas?

I have no idea why your preview looks so awful, something is very wrong there.
Maybe your GPU is messing up
Should be very clean with GPU off, almost identical to the final output.
I'd suspended my adobe sub until this feature is added back.
I left some feedback day one of 12.3 release, there was a fix rumoured
You are right, for very high levels of sharpness the two won't match.
You had to use silly sharpening levels to prove a point.
12.2 show the 2560px result at 100% and shows the sharpening at that size.
E.g. You can see how the sharpening and noise reduction looks at 100% for a set of say 4K images.
I make a point based on my actual usage of the software.
On most images at the sharpening levels I use, it is close enough to be a useful feature.
The funny thing is, you can use the ALT key to preview the masking and other sliders on the reduced 100% view.
Leaving the warning to say it might not be identical would be OK, an improvement perhaps, but taking the feature away completely is not OK.
In 12.2 I can judge if the sharpness of an image is acceptable as it will be delivered at 4K. Simple as that.
I'll leave it there and we can see how 12.4 turns out.
Andrew, with a sigh I will ignore your approach to me and my professional work, and instead thank you for the offer of further education.
Meanwhile the actual issue of 12.3 being apparently unable to display final output size with sharpening remains.
I'd love to read your manual for PKS, thanks.
1. As I mentioned in the 2nd post of this thread, the only accurate way to view capture sharpening (and that's key to state; capture sharpening) is at 100% preview (Develop in LR, or main window ACR). Odd zoom ratio's greater, depending on display can be iffy.
Library module now uses nearest neighbor interpolation same as the export module.
Andrew Rodney said "Library module now uses nearest neighbor interpolation same as the export module."
Andrew, bad copy and paste–I never said that!
Library module previews were created using bicubic interpolation same as the export module.
How can we improve?
