The creators of RAW digger & FastRAW Viewer are working on a software that should handle compressed Fuji RAW files much faster. Since this is something many X-shooters could profit from and Iliah is asking for feedback, I’m happy to share it here on FujiRumors.
We are preparing an open source release of decompressor as a part of LibRaw. That will allow raw converters, including open source ones like RawTherapee, Darktable, UFRaw to decode FujiFilm compressed raw files.
To thoroughly test the decoder they incorporated it into their FastRawViewer and RawDigger. Please do try it and let them know through email@example.com if there are any files that cause problems.
Up-to-date manual: http://updates.fastrawviewer.
In FastRawViewer, they suggests to use Preferences – Performance – Use high speed preview for Fujifilm X-Trans setting with this camera, unless you use a very fast computer.
After some beta testing of RawDigger and FastRawViewer with this decoder (5, maybe 10 days) they will publish the decoder as a part of LibRaw open source.
