Hmm. Strange. Shows all the info about my card, except for the shaders.

Can’t be arsed to watch it, but let me guess: the “old computers” in question are ones with dual- or quad-core CPUs and no hyperthreading, DDR3 RAM and (probably most importantly) pre-Vulkan GPUs?

Having to clean my real cat’s sandbox is gross enough that a game about it is quite unappealing. ;0

Bearing in mind that should you be running an LTS release, you’ll still have to add a PPA to run the very latest variant of Mesa.

Other than Mint (which ships with Mesa 23.0.4, even with the “Edge” ISO release which has kernel 6.2), is there any other distro whose current version is using a 6.x kernel that isn’t running the required Mesa version?

The only real reason that AMD is considered better on Linux is that, due to the drivers being in the kernel, they’re less fiddly to get set up than nVidia cards since you just need to plug 'em in and you’re good to go (with the only real caveat being that you need a 6.x kernel if you want to put in an RX 7000-series card).

Otherwise, it’s philosophical differences (closed vs open source) and performance issues (for both manufacturers) that are mostly on an application-by-application basis rather than general.
