I tried Proton 8.0-4 and Proton Experimental - same issue, same log output. I think it's something within the Steam itself (reaper or steam-launch-wrapper or runtime or I have no idea).
Hello @cprn, looking at your extended diagnostics information, it looks like you do not have a 32 bit Vulkan driver installed for your video card. Please add the lib32-vulkan-radeon system package and retest.
Oh, f... me! It works flawlessly now. I'm very very sorry, this can be closed. Why it worked without 32 bit driver when started by protontricks-launch, I have no idea.

Symptoms
Bear with me, please. The game doesn't start. It used to start for me with Proton without issues about 3 years ago but there were many updates since then and I changed the GPU from NVIDIA to AMD.
I read the attached Proton log and it seems to be failing due to missing
VK_KHR_surfaceextension but it doesn't make any sense since it's a very basic extension and other Vulkan games requiring it run fine (e.g. Ancestors: The Humankind Odyssey). Also it runs fine if I run it in terminal usingprotontrickswithout Steam like so:The only issue then is the Steam Controller doesn't work (as in: it works in kb+mouse desktop mode).
I tried many things but failed to find a solution.
When I run the game natively (without Proton) it starts, menus open fine but after starting the game the screen is black - I can move the mouse cursor, I hear shots when I click but nothing is rendered. When I was on NVIDIA I had that issue as well but back then I managed to resolve it by setting the game to the same resolution as the system (1440p) but it doesn't make a difference now (I'm in 4K now, tried in 1440p as well, still a black screen). Regardless, back then the native version was crashing to desktop after a few minutes, so I'm assuming it's unplayable on Linux without Proton anyway.
