I was wondering if Krita takes advantage of multi cores. I have a quad core, a gig of video ram and 24G RAM so I have plenty of horsepower but sometimes paintings tend to lag. That brings up another question that just now occurred to me.What's the maximum size hat Krita can work with?

Digital Painting is not one of the tasks that benefits from multiple cores or technologies intended for maths.

The reason why we're doing this campaign: https://www.kickstarter.com/projects/kr ... -than-phot
Is because we'll then be able to leverage a technology that'll allow us to speed up Krita by making use of the RAM.

Krita does use all of the cores e.g. https://slangkamp.wordpress.com/2010/10 ... rocessing/ It also does use SSE and AVX extensions. So more core helps, but currently we are more limited by memory access.

The maximum size is limited by the amout of RAM in your PC. After that the performance would got down.

Yeah, I know this type of software is really memory intensive, especially when smudging etc ans I tend to use big canvases. Just curious, no problem.
