I recently built a new pc and since I switched from Windows to Lunux (Kubuntu) I got an amd gpu (6700 XT). Because people told me it is less of a hassle than Nvidia. It works fine out of the box, but the choice of drivers confuse me. For gaming is the default amdgpu good enough? Is amdgpu-pro the same as the official Radeon drivers from amd? Are they better for gaming? Is Mesa yet another driver or something in addition to a driver? Why are there no settings/gui anywhere (using the default amdgpu)?
Yes, it even works through flatpak-sandboxed Steam. I had to install a GE-version of Proton to make it work in the early days, but I guess it will now work with the default Proton version shipped with Steam.
