Interesting. My system is an Apple Mac mini (2018-2019 version) running latest macOS (Catalina 10.15.5). It has a 3.2GHz Intel i7-6 core processor and 32G RAM, and an Intel UHD Graphics 630 display driver with 1536 MB on-board RAM and a 1T SSD. Catalogs and data are all on an external USB-3.1 bus connected to a hub and enclosure all supporting USB-3.1.
I did a test of rendering out 100 Hasselblad 907x 50 Mpixel raw files with the GPU graphics acceleration on and off, zero difference (~3 min 35 seconds or about 2 seconds each). RAM usage in the system activity monitor never exceeds 7 Gbytes, and the GPU indicator is never non-0. If I import 12 new raw files and step through them at 1:1 display view scaling, there is about a 1.5 second delay per exposure the first time as the previews are built, otherwise no delay at all. I don't know how to relate this to the performance you're reporting. Operation when editing seems fast and smooth to me. You piqued my curiosity so I looked up Loupedeck+. It looks interesting but I'm not sure what advantage it might have for me, for still photo editing. My muscle memory for LR is such that a long, complex rendering adjustment really takes only at most 90 seconds per frame. I suspect that it might be more useful for video editing, maybe…? just don't know.
