Third party support has a lot to do with how Linux works though. There's a reason Valve basically abandoned the idea of native Linux games and invested in Proton instead, for instance. It's because everything above the kernel in Linux is kind of a garbage fire when it comes to consistency and compatibility. You usually can't even run a binary compiled for Ubuntu 20.04 on 22.04 despite them theoretically being the same OS two years apart.

Driver support is hindered by the lack of stable driver ABI, basically forcing drivers to be FOSS and mainlined. Granted, this also has some advantages.

Valve isn't abandoning the idea of native Linux games. It is up to the game manufacturer. There are probably about 150 games in my Steam library with native support.

I think the issues you are referring to about compatibility have to do with dynamic compilation and something like glibc, which mostly is a compilation risk that you end up taking but the only times I've encountered it the other packages were already available in my distro and so it was just a matter of updating packages. That is why you should find a distro that is quick to update.
