Aus den Release Notes:
Improved performance for Sony files
Sony files load faster from the disk, enabling faster preview generation and rendering when zooming to 100%. The individual improvement will vary from system to system as it depends on disk speed, raw file size and other components.
This will be particularly noticeable if working from a network disk.
Cool. Bis dato war C1 auf meinem NAS ziemlich spaßbefreit. Mal sehen, ob das besser geworden ist.
