Description Radium-bit 2020-08-29 14:35:46 UTC

SUMMARY
Hope to increase the CPU usage of the rendering process.

STEPS TO REPRODUCE
1. Perform oil painting filter rendering.

DESCRIPTION
In Krita, the CPU processing thread has been adjusted to the highest. But the CPU usage is still only about 25% during processing. I want it to increase the CPU usage as much as possible when processing images!
In order to take care of some other needs, maybe you can add a new option called the highest CPU usage setting in the performance menu.

Erm, well, what is going on is that the filter in question is not multithreaded, so it will always use only one of your cores. 

It looks to be a convolution-like filter, but it would need a closer look.

It's one of the older filters taking from a nineties thesis. It cannot be multithreaded because of the way it works, I'm afraid.
