When the drivers are too outdated for you, you're using the wrong Distro. It's not like you're compiling Linux-next and you also didn't manage to fix your installation of newer drivers and no have broken dynamic linking in the userspace part of your gpu drivers. This is just what you get if you buy a GPU from the company that is so miserly with Linux devs that their Linux GPU drivers are only usable from 6 months after the product launch on. Or only buy their products when they're more than a year old. You wouldn't get your card running on Windows 7 or a very old Windows 10, either.
I'd strongly suggest you switch to Ubuntu 23.10, the most recent Fedora or Arch (archinstall is official now). Cinnamon desktop is in the repos for all of them, no need for Mint. The share objects that try to link wrong should be fixable but even if I'd sit in front of your Computer it'll may take some hours for me if I'm really unlucky.
https://ubuntu.pkgs.org/22.04/…1-0ubuntu3_amd64.deb.html should exist, maybe you don't have the universe Repo activated in the apt sources? sudo apt edit-sources and remove the comment around universe. If it's not in there, pls search on the internet on how to enable Ubuntu universe or get some guide how to do this on Mint if they deviate from Ubuntu there.
if i dont actively activate basalt shouldn't it just be silent or idle
I didn't care to check if it installs some layers so you may be right. Given that Tpf2 in OpenGL mode crashes with a seemingly not graphics related issue, we don't have to care about it yet. But Vulkan certainly loads it all the time or Steam wouldn't have picked it up.
Nr. 2 is a wrong assumption, I guess I didn't state the explicitly enough ;D You have both Snap and Flatpak installed but installed Steam via apt. Steam does still have its own runtime container with different libraries, though. Forget 2 and this for now.
