However, even during my quick testing, the MyPaint brushes in GIMP lagged quite badly when used in a high-resolution image, even on my extremely powerful desktop computer. It’s hard to paint when your brush stroke appears 3-4 seconds behind your cursor position, which sort of defeats the purpose of having such fancy brushes.īy comparison, Paint Tool SAI’s brushes only started to lag slightly when I pushed them to their very highest quality and complexity. This may not be an issue if you only want to paint for the screen, but if you’re ever planning to print your artwork, you’ll need to work in a high-resolution format. Paint Tool SAI also offers specialized Linework layers that use simple editable vector lines to help sketch/map your painting project. GIMP also allows you to use multiple layers, but it doesn’t have vector support beyond very basic paths, which I find to be quite frustrating in practical usage. GIMP offers a huge range of flexible brushes and options but can lag severely when working on high-resolution images.

Paint Tool SAI has near-perfect responsiveness at large sizes, although it doesn’t offer as many brushes by default. Most digital artists prefer to work with a tablet and stylus, which provides far better control than a standard computer mouse.
