VK_ERROR_INITIALIZATION_FAILED: Shader library compile failed error: use of undeclared identifier 'spvSwizzleConstants'

[ezamelczyk]

So I'm trying to run Gothic with GD3D11 renderer and I'm really out of ideas on how to troubleshoot this.

These are the steps I've taken:

• I've created a wrapper using Wineskin Winery 2.9.2.0 with engine WineskinCX 23.7.1
• installed the GOG version of Gothic
• installed GD3D11 renderer
• installed dxvk_master, dxvk_master_dxgi, directmusic, vcrun2010 and also added manual override ddraw=n,b needed for GD3D11 to work

And this is the setup I'm stuck with because the game launches with a black screen but it definitely works under there because I can from memory select new game and I hear that it launches.

The problem is that the vulkan pipeline fails to initialize with this message:

[mvk-error] VK_ERROR_INITIALIZATION_FAILED: Shader library compile failed (Error code 3):
program_source:86:34: error: use of undeclared identifier 'spvSwizzleConstants'
    constant uint& s_imageSwzl = spvSwizzleConstants[0];
                                 ^
program_source:87:34: error: use of undeclared identifier 'spvSwizzleConstants'
    constant uint& s_gammaSwzl = spvSwizzleConstants[1];
                                 ^
.
[mvk-error] VK_ERROR_INVALID_SHADER_NV: Fragment shader function could not be compiled into pipeline. See previous logged error.
err:   DxvkGraphicsPipeline: Failed to compile pipeline

I have no idea where that spvSwizzleConstants comes from as many people used the same setup as me and it works even on steamdeck. I've scoured the whole internet in search of an answer but I failed miserably.

Can anyone help me troubleshoot this?
