Phoronix: AMDVLK 2019.Q1.1 Radeon Vulkan Driver Build Now Available For Ubuntu

AMD developers have now offered up an AMDVLK Vulkan driver build for Ubuntu as a Debian package based upon yesterday's source drop...

Just tried AMDVLK for the first time now. Was mostly interested in seeing if it was affected by that x.org 1.20 bug that prevents fullscreen Vulkan apps from running in Wayland sessions, but Dark Souls III launched just fine so I guess that's just RADV. Yaay, now I can use DXVK on Wayland

spelling.

Does this driver fix issues seen with AMD RX 590?

[Brisse]

debianxfce I've got i3 installed alongside GNOME for those times when I want simple, and I agree GNOME on Wayland isn't quite good for gaming yet although it's gotten a lot better recently with things like HW Presentation Timing being implemented (that patch is already included in mutter on Debian Sid).

Also, interestingly, it seems DXVK with AMDVLK is running as a native Wayland application. When I run 'xlsclients' the only application I can see is Steam.

After spending some time testing AMDVLK with Dark Souls III and NieR: Automata I have concluded that it stutters quite a lot more on Wayland. On x.org things are smooth, similar to RADV but I did get a GPU hang in NieR: Automata after a while so I guess RADV is still more reliable, at least for DXVK/Proton.

Tried setting ShaderCacheMode,2 in /etc/amd/amdPalSettings.cfg ?

[Brisse]

ernstp Nope. I don't seem to have this file. Is it something I could create or could it be somewhere else? What is this setting supposed to do?

It's in the README here: https://github.com/GPUOpen-Drivers/AMDVLK

It caches shaders to disk.

ernstp Now it's making sense. It did feel like I was having some shader compilation stutters and if runtime cache is the default then I guess that's going to be the case every time I restart the game.

Doesn't explain the GPU hang or the Wayland stutters though. The latter is probably not a driver problem though because I get that in a lot of games and not just Vulkan games either.
