On AMD cards, it’s working out of the box since Mesa 23.1. I don’t know how it performs compared to Windows.

I may be wrong, but I think DirectStorage is just part of the D3D API and being translated to Vulkan with VKD3D.

I love physical media because it’s so easy to get rid of it whenever you want. Are you sick of a game or don’t want to touch it ever again? Resell on the used market for a few bucks or give it to a friend or a young neighbor that might appreciate it. I like to keep a lean collection of games that I actually care about and might replay eventually.
