Astrophotography Stack Unbelievably Slow! 1.9.1

[ds.johnston]

Hello,

I updated Affinity Photo today from 1.9 to 1.9.1

With 1.9 the Astrophotography Stack feature just crashes and didn't work at all.

With 1.9.1 the Astrophotography Stack feature is incredibly slow. I have taken a screenshot of the status bar after 30mins.

I'm only stacking a small number of frames consisting of:

Lights frames = 22 x 4min @ ISO500

Darks = 17, Bias = 50, Flats = 50.

All frames are CR3 Raw files.

My laptop is an i7 quadcore so it's not exactly slow.

My complaint is that your YouTube videos show the Astrophotography Stack feature completing the processing in seconds. 

Can you address why you have made advertising videos showing this feature working so quickly when the reality is extremely different? This seems really disingenuous and is false advertising. 

If you're going to sell a product with a feature like this then it should definitely outperform free products such as Deep Sky Stacker, which can complete the stacking process much quicker (never had any problems with Deep Sky Stacker).

I would really appreciated hearing from an Affinity developer on this issue.
