PPI and performance

[ferze]

So I noticed that Artstudio pro doesn't have Dpi? but instead have ppi
my problem is that when I just want to doodle I usually resize the canvas to make it bigger
And that's make the app crash so I try to change the dpi but i only found ppi in the resize image settings
The question is Is it affect the performance at all when I scale down the ppi?
And where is dpi

PPI, DPI, sometimes also Resolution - it is the same.

The performance depends on canvas size in pixels and number of layers. You can check size in pixels in File > Information, or when creating a new image, or in Image > Resize Image.
