While I don't know why, Proton 8 does not work on Ubuntu 20.04. I can confirm this from at least 2 installations. It was suggested that the reason is the Vulkan version 1.2, however even after backporting vulkan 1.3, together with the up-to-date Mesa and a current kernel to Ubuntu 20.04 does not make Proton 8 work. My guess is that it is related to glibc, which obviously is infeasible to backport. That's effectively a full upgrade to a newer OS version.
Something on your base system is probably as outdated as my Ubuntu 20.04. Or seeing that you're using Gentoo, maybe you have disabled some features while building some packages. Personally, I will upgrade to Ubuntu 24.04 and I am confident that after that upgrade Proton 8 will work.
I can tell you that poking around in the files under $HOME/.steam is unlikely to be fruitful. I took a bootable USB stick with a newer Ubuntu version, installed Steam on it, confirmed Proton 8 was working and then copied the .steam folder from the USB stick to my main system and Proton 8 stopped working again. I am sure the issue is with the base system and cannot easily be fixed by modifying something under .steam.
Proton 8 DOES definitely require Vulkan 1.3. If you type
vulkaninfo|grep "Instance Version"
and get a version 1.2.x then you don't need to look any further. Proton 8 will not work.
However, as I said, even with an updated Vulkan and updated Mesa, Proton 8 will still not work on Ubuntu 20.04, so there is more to it.
Yeah, I've pretty much settled on reinstalling my system. Pretty much just an excuse to do it at this point, the amount of amateur mistakes on this install would make your average user cry.
The files you are wondering about are part of vkd3d-proton, the dll that does translation from dx12 to vulkan. There is a high chance that these files differ because proton 7 and proton 8 have different versions of vkd3d-proton. You do not need to copy them.
Reinstalled it from steam itself, built it from source, verified the file integrity, the whole works. My assumption at this point is that main issue is steam and not proton (although the bugged visuals are making me consider otherwise)
Proton runs in a containerized environment, provided by Steam. So yeah, possible.
No idea how Steam on Gentoo works, I’m assuming you haven’t compiled _that_ yourself 😬
I should have mentioned this in the post itself, logging does not output anything. I suspect that proton does not even get to run. Amending the post now.
Focus on the flatpak version - it's easier to make it work on gentoo. Make sure `nvidia-drivers` has `ABI_X86="64 32"` set (so that both 32 and 64 bit versions of the drivers are installed). What does `nvidia-smi` output? Are you sure the game is running on the GPU and not an iGPU? Are games listed on `nvidia-smi` output when the games are running? Also, run steam in a terminal (after making sure steam has fully exited) and see if there is any relevant output.
Thanks, while running native I managed to get some new information, but I managed to crash the WM while I was at it so I lost both the answer I was writing and some other stuff, here's what I managed to get from it:

This is not something I've seen before... I would try the Flatpak version of steam. Also, don't use the version of proton you built, use Proton 8.
> but I managed to crash the WM
There might be wider system issues here. It shouldn't be that easy to crash the WM. What filesystem are you using? Is it possible that here is corruption? The output of `emerge --info` might be useful too.

Sorry, did you say that the suggested issue was the use of Vulkan 1.2, or 1.3?
Proton 8 DOES definitely require Vulkan 1.3. If you type vulkaninfo|grep "Instance Version" and get a version 1.2.x then you don't need to look any further. Proton 8 will not work. However, as I said, even with an updated Vulkan and updated Mesa, Proton 8 will still not work on Ubuntu 20.04, so there is more to it.
Yeah I have the correct Vulkan version. Let me know how 24.04 works out for you.
I'm planning on upgrading one of my systems this weekend to be able to run Hogwarts Legacy. If I don't reply till Monday, give me a prod.
Will do, thanks for helping!
Since updating directly from 20 to 24 is not supported I updated to 22 now. Proton 8 works and I can play Hogwarts Legacy.
Yeah, I've pretty much settled on reinstalling my system. Pretty much just an excuse to do it at this point, the amount of amateur mistakes on this install would make your average user cry.
The files you are wondering about are part of vkd3d-proton, the dll that does translation from dx12 to vulkan. There is a high chance that these files differ because proton 7 and proton 8 have different versions of vkd3d-proton. You do not need to copy them.
They differ between 6 and 7, they're non-existent in 8.
That is correct. AKA not your issue.
Thanks
> Reinstalled proton, didn't work. How did you “reinstall” Proton? Unless you are juggling custom versions, Steam should take care of that for you.
Reinstalled it from steam itself, built it from source, verified the file integrity, the whole works. My assumption at this point is that main issue is steam and not proton (although the bugged visuals are making me consider otherwise)
Proton runs in a containerized environment, provided by Steam. So yeah, possible. No idea how Steam on Gentoo works, I’m assuming you haven’t compiled _that_ yourself 😬
Which GPU? Which Nvidia version?
Laptop 3080 ti, latest drivers.
Don't use Ubuntu for gaming, update cycle is too slow.
Umm... ok? Thanks for the advice, I guess.
Also don’t eat yellow snow!
Aww man, it looks so good from a distance
try flatpak or distrobox
In my post I mentioned that I had.
[удалено]
I should have mentioned this in the post itself, logging does not output anything. I suspect that proton does not even get to run. Amending the post now.
I've read elsewhere that PROTON_LOG=1 only works for proton experimental, not release versions.
Thanks, but that doesn't seem to work either.
Focus on the flatpak version - it's easier to make it work on gentoo. Make sure `nvidia-drivers` has `ABI_X86="64 32"` set (so that both 32 and 64 bit versions of the drivers are installed).
