Vitae Windows Save Big File Video
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.
