Problem rendering in Develop module when scrolling photo full screen

For Camera RAW CACHE Settings, 10 GB

Ok, I was half way expecting 5 GB. Adobe states that the default value of 5 GB is too small, to try at least 20 GB.

So you do have more than the default, but just 10 GB. Perhaps bump that up to 20 GB or more.

The Camera RAW CACHE limit will effect Develop Module edits. it will not effect Library module edits. It is where the Develop Module previews are created, so too small, poor performance. The larger the LrC session you have in terms of photos being edited, the larger this needs to be. Most people find they need to experiment with this as their are no fast and hard rules on it (how much is enough??)

P.S. the Camera RAW CACHE does not need to be in the default location. It can be on any hard drive, any folder. It does not need to be in the same location as the catalog or the photos.  Now the Camera RAW CACHE can take advantage of being on your fastest hard drive (as so does the catalog as well, but not the photos). You might see performance improvements if you take advantage of that. And on a Windows PC, some state to try to avoid placing it on the C drive where your Windows paging file is located due to the two completing with read/wrights, but that is a very small performance hit, and may not be worth the trouble.

Hi

I tried delete all the preview.  When preview are deleted then If I scroll then the word 'Loading' appear and stay like this forevever until I press a key like 'next' or 'back' .
