Recently bought a RX7600XT and experienced lagging in Krita and flickering in blender since. I installed the drivers from AMD’s website, and ROCm.

I am unsure and totally overwhelmed as to what could cause these issues. ChatGPT always wants me to edit /etc/default/grub, but I am not sure why and what the bootloader has got to do with it?

These are quite a lot of questions and few information. If you need anything I am more than happy to provide any information.

    You should not ask chatgpt for these things, you should look for documentation and forums. A good place to understand how things work is the arch wiki, even if you don’t use arch, most of the stuff is valid for other distros… except instructions on installing packages, that you should look in your distro’s specific documentation and forums.

      If you read the documentation you would know that:

      • Drivers have a part in the kernel and some others outside the kernel
      • The part inside the kernel is called amdgpu most likely already installed and you don’t need to do anything
      • For the parts outside you can use either amd’s (the ones you tried to install) or the community made ones (mesa)
      • Amd’s own stuff is better only in raytracing and worse in everything else, so unless you are doing raytracing you should avoid it and use mesa
      • Mesa is likely already installed and you could have just done nothing, if not look up how to install that
      • If you still want amd’s own stuff, or if you want rocm, you should look that up on mint documentation and forum

      Footnote: it is possible to install both mesa and amd’s software, and set up some games to use one and some and everything else to use the other, this allows you to always use mesa, except for those games with raytracing, but seeing that you are already overwhelmed I would avoid that for now, and maybe try if when you are more experienced.
