Version of ArtRage: 4
Windows 10

I'm not sure if this is necessarily at technical problem, but when I begin drawing a picture, I can never get enough detail in it. I'll be drawing something, and then I'll zoom in to make a portion of the picture a bit more detailed. However, it just comes out fuzzy. I figured that increasing the pixels per inch would solve this problem. But when I try to increase the pixels by inch portion to allow for more detail, the program crashes.

So, I guess what I'm asking is (for anyone and everyone who can help) what is the best canvas, page length/width, and pixels per inch to allow for a decent bit of detail without the program crashing all together? Or if you don't know at what point it will start crashing, then what are your guys' favorite settings to use in general?

Thanks for anyone who can help.
