When I open a Nikon NEF file directly from PhotoShop I get the same poor performance of ACR processing. This problem is now isolated to just PhotoShop and ACR. It is taking up to 6 seconds to get a brush cursor in ACR after selecting the Adjustment Brush tool. It now takes over 60 seconds to turn on and off Adjustment Brush masking. Moving the Exposure adjustment slider takes 12 seconds to see the results.
My system:
Photoshop version 21.2.1
ACR 12.3
Nikon NEF files
Windows 10 Pro, version 1909 64 bit
Intel Core i9-9900K @ 3.6GHz
32GB of memory
GeForce RTX 2080 Ti GPU
NVIDIA Studio Driver Version 451.77 released 7/16/20
If you are creating a Smart object using Photoshop, then why are you using the Camera Raw filter instead of Camera Raw? If you're just using the filter there isn't much sense in creating the Smart object. Even though you have taken the time to create the Smart object, the Camera Raw filter won't give you access to the raw data like double-clicking on the object in the layers panel will.
Thanks for your response Jim. I am new to this workflow. I normally just use LRC to do my raw file editing but I thought I would try a workflow method recommended by Aaron Nace. Anyway, once in PS I create a smart object but when I double click on it in the layers panel I get a new editing panel that is just PhotoShop's editing panel not ACR editing panel. Is this correct? I guess I need to figure out what I am doing with smart objects.
In LrC, in Preferences, in External Editing, what are your settings for Edit in Photoshop? One issue being file type. And very important, any compression selected.
Thanks for your response David. My LRC External Editing preferences are as follows: TIFF file, ProPhotoRGB color space, 16bits @ 240PPI. I get the same results using both a compressed and uncompressed TIFF file.

Be aware, starting at v9.3 (or was it 9.2) selecting to compress the TIFF actual does such, before, it did not really accomplish that. Resultant TIFF sent over to PS will then take longer, sometimes much longer tp load
Yes David, I removed Lightroom from my workflow and I am now opening a Raw file directly from PhotoShop. I am experiencing the same issues in slow processing with ACR so Lightroom handoff has nothing to do with the problem. I moved the discussion to the PhotoShop thread.
David, one of the options in Lightroom "Edit In" is to launch PS is to "Open as a Smart Object". If you do this with a RAW file ACR automatically starts so you can edit it.
That isn't the way it works on my computer. If I choose to open a raw file from Lightroom as a smart object then it will open into the Photoshop editing screen "normally". In the layers panel the little icon (not that lettering) indicates that this is an object, and if I double-click on that icon then Camera Raw will open. This isn't the Camera Raw filter, but rather Camera Raw and gives me access to the raw data in my file. So I can move back and forth between the converted RGB data in Photoshop and the raw data as needed until I'm satisfied.
