Lutris doesn't detect Vulkan when using Wine 9 compilled with wow64 and -abi_x86_32 on gentoo

[Amilton78]

Something on Vulkan support detection probably is trying to find something not strictly necessary to use DXVK and VKD3D, likely some 32bit version of a Wine dependency, I'm able to play GoW 2018 no problems outside Lutris, as it wouldn't let me enable DXVK

It works just fine in my system without those 32 bit versions of those .so files

[strycore]

find this bit of code in lutris/util/linux.py :

    @property
    def runtime_architectures(self):
        """Return the architectures supported on this machine"""
        if self.arch == "x86_64":
            return ["i386", "x86_64"]
        return ["i386"]

and replace return ["i386", "x86_64"] with return ["x86_64"]

This should solve it.

We have to add support for pure 64bit systems.

[Amilton78]

I hope pure 64-bit support gets added to lutris as wine gets better with 32 to 64-bit translation and versions like GE starts using it

[strycore]

Yes. it will get improvement.
Wine 9 is just out and it is not a version we support currently.
We support wine-ge-8-25 and that's what you should be using right now.

and replace return ["i386", "x86_64"] with return ["x86_64"]

This hack worked for me on my pure 64bit system.

It just came to my mind I could make a .patch/.diff for emerge to build the package with this, thanks!
