Very slow to load new Presets (LUT's)

[Geoff Stokes]

If you create a new Presert (LUT's) from an external *.cube file the next time you start Photo and select LUT from the Adjustment menu the program is very slow to load the new LUT.

At times it can also result in the program failing and requiring a reboot.

This slow reaction is worse the more new Presets (LUT's) you create.

If you create the new Preset (LUT) using the "Infer LUT" option, and using a reference and sample *.png files the problem does not seem to occur.

Hey Geoff,

I have reproduced this - thanks. You're also correct about Infer Lut. I'll get this back to the developers.

Many thanks for the feedback

Same here (on Windows 10 Pro 64-bit, Ryzen 9 3900X, 64 GB of RAM, fast SSD).

Imported a pack of 80 "*.cube" LUT files when I saw you can do that, and now when I select "LUT" on the adjustments panel, AP becomes unresponsive for a few minutes (!). It doesn't help that the application has no general concept of properly indicating it's busy doing something and showing progress, the greatest niggle I have with the entire tool suite... To me, it seems like all those files are loaded from somewhere as soon as one clicks that option, instead of them being loaded individually only when selecting a specific LUT.

Sorry to hear you have the same problem, I think its being investigated. I have stopped trying to add *.cube files, use individual ones from an external directory for the time being.

Did manage to install eight Fuji Film LUT's but this was using first the "Infer" option (with *.png files) and them saving that as a new preset.
