Library Module should be as fast as Develop Module when Previews aren't pre-rendered

[jjjdfkdiiiejsjnxniie]

If previews aren't rendered, when in Library Mode, images "clear up" much faster in Develop Module than in Library Module. In fact, Library Module can take several seconds just to clear up enough for you to make sure you nailed the focus! It's so bad, that I either have to render Previews (and twiddle my thumbs or find something else to do for a while), or just go into Develop Module to begin with.

When Previews haven't been rendered, why not have Library Mode just load the full-images the same way Develop does, since it's so much faster? Seems like that would be more efficient for those of us with massive libraries, who have to occasionally go through old folders. Maybe have it recognize that the Preview isn't rendered, so rather than taking its sweet time rendering previews while the user stares at a fuzzy image for several seconds, then it can load the entire image in a second or two like Develop Module! Then maybe in the background, it can make a preview for if you go back to it within a certain period of time.

If you haven't done so turn off the GPU option in the Performance tab of the LR Preferences and test.

It sounds like the previews have not already been rendered for the Library module. If you are doing this immediately after import, then the computer will take time as it renders ALL of the previews of the newly imported photos, and yes, I think it's reasonable behavior on the part of Lightroom in this situation to be slow showing you the previews in Library module, because the computer has a lot of work to do.

You can set preview prefs to minimal previews e.g. only thumbnail size previews get generated on import. But previews are really designed to be available for when working with the output modules such as slideshow, web galleries, books etc. I use standard previews in the Library for making initial picks/rejects but agree the Develop module can often be better for more critical issues like checking focus. The develop module dose start with the available preview and updates with original image data from the camera raw cache or fast load data in the case of optimized DNG files.
