paint.net uses the hard drive to store temporary files related to editing history. Actual disk space requirements will depend on the type of actions performed and the size of the image.
paint.net is optimized for systems with multiple processors and/or multiple cores. Systems with multiple cores will experience higher performance than dual cores.

If visual artifacts appear, disable hardware acceleration (
