I'm not a heavy duty LR user, by a long shot, but everything I've read is that LR and PS run faster in windows. I usually run LR with an external monitor and for me, the performance has been excellent on my X1E. I have no complaints, of course as I mentioned I'm not really pushing LR, and my image sizes are rather small compared to most full frame cameras - I'm using a Oly OMD EM5 and so images not that large.
I primarily work with larger 42mp Sony RAW images, and both the MacBook and iMac handle them much better with Camera Raw, Photoshop, and Luminar than Windows. Yes, 24mp and lower resolution jpeg files would probably fare better.
Performance wasn’t awful on Windows, but brushes often lagged when masking, opening a new b&w adjustment layer and turning it on and off (which I often use to check my color edits) would lag, zooming in and out was choppy, and using Luminar as a plugin within Photoshop took more time to open and export. I’m saving a good 10-30 seconds each way on the MacBook Pro, which adds up when you use the plugin a lot. That said, Skylum continues to up its plugin game, and this new flex plugin looks like it could speed up workflows within PS on both operating systems.
I really don’t use LR, but ACR is the same RAW engine, and Bridge is used daily for sorting, rating and opening my images.
