Faster Stacking, StackCheck on Autostack & Lightroom, Adjustments using arrow keys!

Version 2026.09.04

Faster stacking!
Note that stacking performance is very particular to your computer (OS, memory, GPU, etc.) In general, camera-raw mode (Raw DNG output, using the Adobe DNG Converter) stacks are nearly twice as fast as they used to be, on both Mac and Windows. On Windows machines without a strong graphics card (meaning they mostly stack on the CPU), normal-mode stacks are roughly 10%-40% faster, and older machines should see the most improvement. In general, the best thing you can do to speed up stacking is to close apps you aren’t using, to free up memory. And in general, Macs are faster than Windows at stacking. Every Apple Silicon Mac's GPU can use all of the computer's memory, so stacking runs on the GPU on every Mac. On Windows, that depends on the graphics card having enough memory of its own (roughly 4 GB or more for a 24 MP camera, more for higher resolutions), and machines whose card falls short stack on the CPU instead.

StackCheck works with Autostack and Lightroom
If you have enabled StackCheck in Preferences, then Lightroom-exported stacks and Autostack will now show StackCheck recommendations.

Adjustment sliders using arrow keys
Hover over a slider or click its text box and press Up or Down. Hold Shift to step ten at a time.

Trial user “remaining days” countdown
Trial users get a countdown, and buying before the trial ends now upgrades the licence you already have instead of issuing a second one.
