First, the PPI (not DPI because graphic programs don't have the ability to deal with DPI which is a printer function) of an image does not affect the file size of an image or have any other effect on editing the image itself. The relevant information you left out was the actual size of the file. If you look at Image>Image Information it will show you the size of the file on disc as well as the size in RAM, which might be helpful.mc_peko wrote:Support for large files.

I'm working on a 600 DPI, 6450 x 4740 px, 8 bits. That is not huge. Still just fixing a typo takes a whole hour, as in 60 minutes.
Can we please have GPU support too?
I have an image open in PSP2018 64bit of a quite busy Christmas scene (decorated tree, busy decorated fireplace, etc) that is 6450 x 4740, 8bit/channel. It is in .pspimage format and about 58meg on disc and 212 meg in RAM according to Image Information. (It's over 90meg on disc saved as an uncompressed TIF file but still the same size in RAM when opened). I have laid down several lines of vector text on several layers. I have no problems editing any of the text in real time. So if correcting a typo is taking a hour then I suspect that you must have other problems.
