Performance

Memory usage and performance Group

 Decoded RAW cache size – the number of decoded RAW files that are kept in the operational

memory (RAM) to boost the speed of the browsing.

 JPEG cache size – the number of JPEG files that are kept in the operational memory to boost

the speed of the browsing.

 Number of simultaneous RAW decode threads – the number of concurrent processes of

RAW decoding.

 Downscale JPEGs larger than NN Mpix – JPEG files larger than the specified size will be down-

sampled during the decoding process, so less memory will be required, while decoding and

display will happen faster.

 Do not decode RAW files larger than NN Mpix – RAW data with a pixel count more than the

specified will not be decoded; only an internal JPEG will be shown (if it exists)

All changes made to this group of settings come into effect only after restarting FastRawViewer.
