Thanks for the tips. Honestly I don't remember explicitly installing vulkan or dxvk... I guess I thought they come along with steam? How are these games running at all if I don't have them installed? Or is it just that the AUR offers a newer version or something?

Anyway here's the output of "pacman -Qs vulkan:"

local/lib32-nvidia-utils 470.63.01-1

local/lib32-vulkan-icd-loader 1.2.184-1

local/vulkan-tools 1.2.184-1 (vulkan-devel)

I get no return on "pacman -Qs dxvk"so I guess that's not explicitly installed.

opengl, dxvk , vulkan are graphics libraries in chronological order.

DXVK is the linux equivalent to directx11 I believe, while vulkan is a step ahead.

First you have to install a graphics driver.
Then you have to install dxvk or vulkan (or both) depending on your hardware. This library sits on top of your graphics driver.

The games you are running are probably opengl based old games(I remember seeing winxp and win7 support).

You just have to clone the AUR repo, cd to it, and run : makepkg -si (as normal user).
It will do everything for you , including install deps , create dll overrides in wine etc.

ARCH has official support for both nvidia and amd based graphics libraries.

We need to know the errors you get when launching the game/application. Is your monitor freesync (amd) or gsync (nvidia) ?

What is the output of :

$ pacman -Q | grep -i dxvk
$ pacman -Q | grep -i vulkan

Vulkan doesnt come with steam anymore.

Steam is one way of playing games, there are other alternatives for running games like lutris , PlayonLinux etc.
Either way you can get most of the popular games running on your PC one way or another.

Sorry for not understanding but it would seem I clearly have some form of DXVK and Vulcan working via Steam if I'm able to play most games with Proton? Most games are running fine, MangoHud reports them running under dxvk, etc. I'm just trying to work out Rocket League in particular.

Does explicit installation of dxvk overwrite anything that Steam is doing? I don't want to mess up games that are working fine already.

You do not have dxvk installed from what I can tell.

If it was it would show in "pacsearch vulkan" as :
local/dxvk-bin 1.9-1 [installed]
A Vulkan-based compatibility layer for Direct3D 9/10/11 which allows running 3D applications on Linux using Wine (Windows DLL binary files)

Installing it wont affect your games or steam settings. You can uninstall with ./setup_dxvk uninstall command

Also you are not posting the error you are getting on manually launching the game from a terminal.

Here : I have a intel cpu and a AMD GPU , so

sudo pacman -Q | grep vulkan
lib32-vulkan-icd-loader 1.2.184-1
lib32-vulkan-intel 21.1.6-1

vulkan-intel 21.1.6-1
vulkan-mesa-layers 21.1.6-1
vulkan-radeon 21.1.6-1
vulkan-swrast 21.1.6-1


gives me this.
Both vulkan and vulkan-32bit are installed.

I realize that the pacman package isn't installed, but the game itself runs somehow, and MangoHUD reports that it's using DXVK. See the upper right of this screenshot.

As far as terminal output, it's a bit lengthy, but here you go:

what is the output of glxinfo command ?

Do you have mesa-demos installed ?

pacman -Q | grep -i mesa

Also you need the joyutils or linuxconsole package from the repository to make your game controller work.

I do not know how mangohud works, but I strongly suggest you install the dxvk from AUR.

glxinfo: Output is too long for the forum but you can see it here.



pacman -Q | grep -i mesa:

lib32-mesa 21.2.1-1
mesa 21.2.1-1
mesa-demos 8.4.0-4


My controller works just fine. It's just the performance of the game I'm trying to address. I will install dxvk from the AUR and report back if that changes anything.

Ok sure.


FYI I get this on steam store:

OK I installed dxvk from the AUR, rebooted, and then tried running RocketLeague again. The outcome seems identical to before - playable but sub-optimal framerates.

And yes - Rocket League was taken off of Steam recently by Epic. But it's still accessible to those who bought it on Steam in the past...

Just to clarify to the above:


This is not the case. OpenGL and Vulkan are graphics APIs; DXVK is a translation library (its an acronym of sorts: 'DirectX-to-Vulkan') from Direct3D to Vulkan, which enables DirectX 9+ titles to be translated to Vulkan. DXVK is included in Proton (and Valve actively supports its ongoing development). Vulkan is a 'next generation' API (along with Mantle API (which it is based upon), Metal, and DirectX 12) meant to replace legacy Direct3D and OpenGL (it runs on Windows too - same is true for DXVK as well). You shouldn't need to separately install packages for DXVK for a Proton environment. This would not appear in glxinfo or similar because, again, DXVK is not an API nor part of OpenGL.

Correct - you have DXVK installed as part of Proton's runtime. You would only need to load these packages manually if you were going outside of Proton (e.g. if you were manually installing Wine and building up from there). Vulkan is included by default in many distros these days, just as OpenGL is.

My completely cynical guess in light of this:
Is that there's some active anti-user/anti-linux/etc tomfoolery going on here - that seems to be par for the course with that developer these days...

That's what I had mentioned a few posts ago. I was not able to find Rocket League yet someone else was telling me that he was able to find it.
I have not bought Rocket League, so I guess, the searches gives nothing in my case.

For anyone looking for a "solution". I had switched back to Windows for a while, but I want to try Linux again.
I've installed POP OS 21.04 (with the NVidia drivers), and Rocket League seems to be working perfectly.
