We are always trying to improve Krita’s performance in every area. Last year’s big performance project was multi-threading the pixel brush engine. Krita is now smart enough to let each of your computer cores calculate the dabs separately, and also have them work together. You can decide how many cores Krita will try to use for this in the performance settings! These changes only affect the pixel brush engine for now, but we can later expand this out to other engines like the color smudge.

Speaking of performance improvements, all brushes now have an “Instant Preview threshold” property. This probably sounds confusing, but this speeds up a lot of smaller brushes where Instant Preview didn’t have any performance improvement. Instant Preview will automatically turn on when a brush’s size gets big enough. You can right click the “Instant Preview” checkbox in the bottom of the brush settings to change this.

The work on multi-threaded brushes was sponsored by Intel.
