Updated a couple of times this week and now using version 3.05 on Windows 10 latest updates. Same process that I did before from TIF 16 bits to TIF 16 bits or from TIF 16 bits to jpeg takes forever from 6000px width > 12000px width.
Moved to a other computer for further testing with a Xenon processor also on Windows 10. Did try it with "Use dedicated Graphics Processing" shut off but no change. By the way the text: "Use dedicated Graphics Processing" is getting outside the drop-down menu, because of the too small fixed width of the drop-down.
Also noticed that at the end of the process the applications "in process icon" keeps turning and I have to close the application to stop it (the stop button doesn't work).
Did an other test on a laptop i7 16 gig Windows 10 from 6000px to 12000px Tiff 16 bits to Tiff 16 bits the process doesn't stop by it self again, I had to close the app to stop. From Tiff to jpeg stops like it should.
Tried to upload a screen video, but no luck.
