**Problem description**

After updating to Leap 16.0, the removal of 32-bit libraries forced me to switch to the flatpak. I added the existing steam library under `~/.local/share/Steam` as a drive, gave the flatpak permissions (`flatpak override --system --filesystem=~/.local/share/Steam com.valvesoftware.Steam`) although most of my games were broken and had to be reinstalled, and steam cloud no longer works. Some games also do not work, for example CS2 complains about some missing signatures.

Onto my current problem, running COE33 I noticed many missing textures, and all white/red/black cutscenes depending on the proton version, as well as terrible FPS.

Using the following launch options:
```
PROTON_LOG=1 %command% -d3d12
```
I am met with the following output:

Without specifying `-d3d12`, I am instead met with the following, indicating it falls back to d3d11:

I can run `flatpak run --command=$HOME/.local/share/Steam/ubuntu12_32/steam-runtime.old/amd64/usr/bin/vulkaninfo com.valvesoftware.Steam`, but truthfully I'm not quite sure what I should be looking for.

I attempted using Proton-GE, but it is worth noting that a few days ago, I performed a `zypper up && zypper dub` and was actually able to run the game with `-d3d12` and everything worked great, so I not sure what caused it to start working and what caused it to stop again.

I highly suspect that DX12 is broken for me entirely, and may be why I had to reinstall some games previously. I'd love to get steam cloud working as well, but I need to back everything up first before reenabling it.

**Does this issue reproduce with native Steam**

Have not tested due to no official package on Leap 16.0, but going to assume no as it was working on 15.6.

Start by reproducing the issue in the Steam Flatpak on openSUSE Leap 16.0, comparing the PROTON_LOG output with and without -d3d12 and inspecting the output from vulkaninfo. Trace the Vulkan device-creation failure and the reported texture, cutscene, and performance problems across the tested Proton versions. Done means documenting a reproducible cause and confirming that DirectX 12 works for Clair Obscur: Expedition 33.
