Thinking about switching to nouveau drivers since I don't really need nvidia's drivers (I'm not really gaming or anything, I'm just drawing) my biggest priority is to make sure Krita runs as well as it possibly can.

So I was wondering if anyone has tested whether Krita performs better under nouveau or under nvidia proprietary drivers on Linux.

Thanks.

In my meager knowledge, I think the Nvidia driver would be used to access OpenGL for the purpose of smoother scrolling. I had to disable OpenGL on the 3.01 Appimage version and enable Software Rendering so that the window's contents wouldn't corrupt after emerging from Hibernate. I have smooth graphics at the moment.

In my thinking, Software Rendering would be close to using the Nouveau driver. As long as your computer has enough RAM to avoid caching stuff on the hard drive, I'm sure your experience should be nice enough.

Hmm are you sure? Nouveau has OpenGL drivers too you know (it uses mesa)

And I require OpenGL for instant preview (can't live without it :O )

I use official Nvidia drivers on Linux and I don't seem to have any performance issues with it. I usually like to give Krita as much memory it can possibly have from the configurations. I usually allocate about 80% RAM out of the available 8GB, about 5942 MiB, and Internal Pool set to it's max of 1188 MiB (20%) and lastly have Swap Pool set to 1195 MiB (25.15%), setting file size limit to 6 GiB seems like enough for just about any work, might be a little excessive but you never know, but works if you got plenty memory to work with.
