Is there a way to decrease the load times for the viewer pane? It's very slow at loading the preview ... up to as 1-2 seconds it feels ...It prevents you fromo quickly looking through files when wanting or needing a preview
What kind of files? Some involve third party viewers.
How fast do they load in File Explorer’s viewer pane?
Mp4 and png mostly.... high bitrate / file size normally.. I use MPV because itrs worked best for me as in viewability... is there a way to override the default player/viewer and implement your own?
See Alternative movie playback plugins at the top of HOW TO: Enable/fix playback of various media formats in Opus for a potential quick fix for MP4 files.
PNG images should not be any slower than any other viewer.
