As computers increase in speed, what is the point of bulking up the size the previews take on the media up when preview size is largely irrelevant.
After installing version 16.3.1, I regenerated catalog previews to the Capture One recommended size of 5120 for my Mac Studio monitor. Capture one is running on a 24 core Mac Studio Ultra with 128GB RAM. Because most of my older files had smaller previews, this increased the size of my catalog (catalog size is largely dependent on preview storage).
I cloned some of the 45K Canon R5 RAW file images and regenerated the preview's size for the clones to 640. There was no difference in the minuscule time to view the image at full resolution and I cannot see any difference in going back and forth between the image with the higher resolution preview and the lower one.
I have been doing this experiment since I started Capture One on my 2009 Mac Pro, and later with my iMac Pro. Decreasing preview size made a difference in time to show a full resolution image on the Mac Pro, but had little effect with the iMac Pro and now has no effect on the Mac Studio. Image quality is identical.
So what is the context in which preview size is relevant?
