Hi, I have a large 1.89GB PNG that is [51k x 42k] pixels big, it's a large map. It takes GIMP about 90 seconds to open it and to get it ready for me to view and edit. I have 16GB of RAM and Windows Task Manager says GIMP uses 8.5GB of it to display this PNG. My Dell laptop was brand-new a year ago, so the CPU's pretty-good for a laptop; the GPU is a baked-in standard Intel one, that manages most things without a problem except for demanding games.
It's not a problem for me that it should be slow to load and edit this image, as I would otherwise cut the PNG up into smaller sections; but I'm curious as to what exactly the limitations are. If I had to guess I would say it is either the CPU or GPU that can't load the large file into GIMP more quickly than that, no matter how much RAM it had supporting it. the Irfanview app could not open the image, so GIMP is doing a better job than it at least. I don't know how other image-editing software would compare—Adobe etc. .
