Performance degradation when editing photos

[satiche]

After I have been editing a number of photos (50 or more, say) I notice the performance of PSP 2021 begins to slow down and it takes longer to complete actions, refresh the palettes etc. as time goes on it gets worse (never to a totally unusable state, though). Coming out of PSP and reloading it clears the problem, which leads me to think there is something in memory/cache not being cleared each time a photo is completed and closed/saved.

I do tend to keep PSP open and available, as I use it every day.

There was the same issue with PSP2020 and the version I had before that (the latter on a different PC)

Has anyone else encountered this? If so, is there a solution? I'm running with 8GB RAM and PSP is running off a 256 GB SSD drive (the photos are loaded either from the SSD or a 1TB HDD) - so there should not be any resource constraints. Nothing else is competing for system resources.

My educated estimate is that you need more RAM. I would suggest 16GB at the very least. I hope you're not loading all 50 images into PSP at once.

Do you have Scratch disk enabled? (File/preferences/general program preferences/scratch disk)
I don't know if it works, but I read a long time ago that it's preferable to set your scratch disk to another disk than your system disk if possible. Or try turning it off if it's on and see if that helps.

Thanks for the suggestions. The memory usage is OK (checking on system resources) so it does seem to be something within PSP - will investigate the scratch disk placement - though I think I tried this before, with little effect.

How many images do you open at the same time?
