I'm trying Krita for the first time (version 3.0), following this Bob Ross tutorial with some custom brushes: https://www.youtube.com/watch?v=aw9LwWcNSgY

Krita is very laggy and slow - such that I can't draw properly.

Is there anything I can do to fix this?

I found this topic: https://forum.kde.org/viewtopic.php?f=281&t=125170 but can't logon to post because the KDE forum is unusable - tells me "Error 403 Client rejected by automatic spammer detection system"

My pc is Windows 10, 16GB RAM, i5 3Gz.

My image is 18" x 20", 300 dpi. At 100 dpi it's slighty better, but the mouse still keeps jumping around unpredictably after I've moved it.

According to the conversation you linked to, disabling OpenGL can cause significant speed improvements in some systems.

Go to Settings > Configure > Display > Uncheck OpenGl

Im my case, Krita was responding very poorly until I unchecked OpenGL, as PieBie also mentions in his answer; once unchecked, however, I was able to move the screen around but the brushes weren't registering when I tried to draw. So I fiddled around and found another setting that was decisive for me:

increase the memory limit under Settings > Configure Krita > Performance

For what it's worth, I had the opposite experience with a Surface Go 2. The Go has a pretty basic cpu but a surprisingly good graphics card that seems to handle OpenGL (and other gpu-intensive software) surprisingly well. So the Go has maybe the opposite situation of many other Windows computers that have more powerful cpu's but just integrated or basic graphics.

Krita installed using "Direct 3D 11 via Angle" for the Display setting, and was unusably laggy. Switching to OpenGL made a world of difference. So I guess it depends on the graphics card in your computer which works best.
