Hi,

I was recently completing a commission of 6 pieces of art, all of around 4K and I created a ptg file with all 6 in a grid of 3x2 During the process of finalising the art I noticed that the save time for the file was 5 minutes plus!, is this normal?, scaling the image to 50% with perspective cut the save time down to 20 seconds, I decided to investigate by creating a simple test, see below:

This test of saving times was performed on a Samsung Galaxy Book Flex 1 i5 (the rest of the computer info can be see on the video)

I am running on Windows 11

Note that Windows Best Performance mode was activated.

For saving an image file size of 15435x6223 pixels it takes around 4:50 to save a file with a single layer, the video shows a test of just dragging a file of this size into a new file and saving as a ptg file.

Then scaling down the whole image by resizing to 50% so the image has 75% less overall information to 7718x3112 pixels it takes around 22 seconds.

Cheers!
