The default driver used by Fedora is RADV. Steam/Proton does not choose your Vulkan driver. That’s why your games run well - you aren’t using the one made by AMD.
This suggests that both (most/all??) are bundled, and you could even run one program in one driver and another program with the other driver.
This was mentioned in that post/thread as well …
Also if you use AMD card RADV is the best for gaming and it’s the default for most distros so it’s an out of the box experience
Its also mentioned that environmental variables can be set at runtime to switch on the fly (at program startup) which is used. I just don’t know if Proton does any of that for you under the covers at startup or if you have to manually add the parameters to the properties for the Steam game to force it to use another one.
I don’t think AMDVLK is even installed by default with Fedora. It can definitely be installed, but there’s not much reason to as it’s a really bad Vulkan driver.

Alright. I remembered them switched around, but there was a migration a year or two ago from one to another, default wise.
Help me with >THIS< then?
