paint.net 4.3.2 is now available! in Paint.NET Discussion and Questions Posted Friday at 02:23 PM The 14MB one? I guess we have an attachment limit. Let me send the 14MB (3200x1280 res) one first to serve as a control but how do I send it? I just re-attempted to open the 29MB PDN now with the memory cleaner turned off this time and it went to a whooping almost 1.3GB usage. This file has 3000x2500 resolution by the way. I don't think I ever had a time that PDN's RAM usage went this high, at least that I know of. The 14MB (3200x1280 res) file still uses up the 800MB range when I opened it again now. I also opened other files with the following stats: (7.28MB file 200MB usage 1344x960 res) (13.1MB file 260MB usage 1600x1280 res) (//should have been closer to the 14MB file but no?) (20.9MB file 570MB usage 3000x2500 res) I guess we might have a resolution size threshold before it starts using too much RAM based from what I was able to gather but with some oddities.
