The size of the caches can be changed on the fly, without restarting FastRawViewer. Flush decoded RAW/JPEG caches on file/folder forced reload (this setting has been moved from the Other performance settings group on the same tab): if the checkbox is checked (by default it’s not), then when using Menu – File – Reload - … caches will be cleared.4 megabytes per megapixel for RGB files (JPEG, TIFF, HEIC, etc.).16 megabytes per megapixel for full-color in floating point (HDR composites and the like).
8 megabytes per megapixel for “full-color” (Linear DNG, Sony ARQ, Pentax 4-shot).2 megabytes per megapixel for “regular Bayer files”.When setting the cache size, it’s important to take into account the amount of memory that is occupied by data:.Default values are set based on the amount of available memory.RAW:, RGB files: size of the cache of decoded files (in files).This tab has been noticeably reworked (in the upper part) Settings for monitoring folder changes and the depths of file Prefetch have been moved to a new Preferences - Performance – Slow Media tab (see below). The Check for folder updates each … setting has been transferred here from the old Performance tab Removable Media Tab New and Changed Performance Settings File Handling Tab Non-RAW files: file type is guessed based on file header.Intel/AppleSilicon Universal binary (single binary for both processor types).Reading (prefetch) of files can happen in the ‘while idle’ mode (‘idle’ here means that there are no other file activities going on in FastRawViewer).When changing the current folder, it will not immediately read too many files at once.When flipping through files, by a magnitude of 1.5-2x (again, when not running into disk data throughput limitations).When reading previews and metadata, by tens of percent (when not running into disk data throughput limitations).Multi-threading can be set separately for each media type (disk, network volume, and even subfolder), and now settings do not need to be pegged to the slowest disk.
