We are now at the point where lobbying looks like a moral option compared to this shit

No, AMDVLK is also a user space driver. You’re confusing it with AMDGPU, which is a kernel module.

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.

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.

You’re missing my point. AMD’s official Linux drivers are ALSO garbage. Try it. Go install AMDVLK and check how well games work. You’re almost certainly using RADV, which was not developed by AMD.

What does that have to do with AMD’s driver support? AMD’s Linux Vulkan driver (AMDVLK) was so late and bad that Red Hat and Valve had to make their own (RADV), which is the default in Fedora and SteamOS. AMD’s first party drivers are still garbage.

Mostly that it doesn’t work on Steam Deck. Hits memory limits IIRC.

Actually it works fine on Steam Deck. It uses VRR over DP to the dock, which then translates it to HDMI with VRR. The dock has proprietary firmware to do this.

Intel and Nvidia hardware with open source kernel drivers also do a similar trick where the HDMI part is in a firmware blob. Only AMD does not work with HDMI VRR.

It’s annoying all the articles are focusing on performance versus stock wine here when basically everyone uses Proton or a fork of it anyway, which has had fsync for years now that does similar performance uplift.

The story here should be that we’re getting fsync level performance with fewer bug and it can be upstreamed to wine. There is no relevant performance uplift for Proton users, but I guess performance gets clicks so that’s the story all the press are going with.

Now, if you want. There will probably always be tradeoffs between the two drivers so I doubt this will ever match Nvidia’s across the board, just have to pick your poisons.
