Ok, it’s fixed.
The drivers were loading and being utilized, just not by Steam. I didn’t realize that when running zypper dup, that I needed to also update my flatpak applications (like Steam) seperately.
So, I checked the versioning of my flatpaks and noticed that “freedesktop” was outdated, still running the 570 drivers, so there was a mismatch between my desktop and kernel’s versions of the drivers. I did a sudo flatpak update -y and got all the updates needed for freedesktop.
Afterwards, everything worked as expected. This was all my own fault for not realizing what zypper does and doesn’t do. But it’s fixed now.
