Required Vulkan extension VK_KHR_surface not supported BUT all drivers/loaders/etc installed for 32+64 bits

[nzbtuxnews]

When I try to start one of the two games I managed to "install" in lutris, I get "Required Vulkan extension VK_KHR_surface not supported".

However, vulkaninfo seems to list the Vulkan extension VK_KHR_surface:

workstation-user@workstation:~$ vulkaninfo | grep VK_KHR_surface

This is on a brand new Mint 20.2 system (freshly installed) running NVIDIA 470 driver, and all vulkan/dxvk/whatever drivers and loaders installed (AFAIK). I have spent hours reinstalling stuff, searching on the web, unfortunately, most bug reports or forum threads end up never being replied by the OP's, or the solution is simply to install the vulkan 32 bit drivers or loaders which AFAIK I have already...

This is the logs of one of the faulty games:

My understanding is that DXVK is calling a function of vulkan and vulkan is replying that it cannot provide it. However, vkcube and other "demos" are running flawlessly on the host OS.

Please provide DXVK logs, both dxgi and d3d11/d3d9, full ones

Also run this please vulkaninfo | grep '^GPU id'

@nzbtuxnews I had to add libgamemode0:i386 libgamemodeauto0:i386 libgl1-mesa-dri:i386 gstreamer1.0-gtk3:i386 libgtk-3-bin:i386 librsvg2-common:i386 to "fix" that issue in wine games. The alternative is to run them with the system wine.
