Update DXVK for nvidia GPU

[Kreyren]

You might need

Run your game with VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.x86_64.json for AMD 64 bit or with VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json for nvidia.

Works now -> DXVK verb update is required

Originally posted by @Kreyren in #965 (comment)

VK_ICD_FILENAMES variable has to be set depending on end-user system for games to work.

We need a way to guess the main GPU on a system and a way to update the _environment variable of the QuickScript from the DXVK verb.

[Kreyren]

@ImperatorS79 Why guess? we can grab the vendor from linux environment

EDIT: Worst case scenario we force user-input

EDIT2: probably if we are unable to deduce the vendor -> force user-input

@plata How could I send the QuickScript to the dxvk verb so that I could update the _environment var ?

[ImperatorS79]

OK I have something that should work, we just have to change the prototype of preInstall and postInstall function:

this._preInstall(this, wine, setupWizard);

Will you MR it?

[ImperatorS79]

It needs #956 first (which needs some changes in the GUI)

[plata]

I think we must query the user because there might be a multi GPU setup (will the system provide the correct GPU?).

[ImperatorS79]

@plata That's what I am doing locally, the fix is ready, but I want your opinion about the preInstall change ^^.

[plata]

Hard to tell without actually seeing it.

[ImperatorS79]

Just changing the prototype to this._preInstall(this, wine, setupWizard); instead of this._preInstall(wine, setupWizard); in any file using it so that I can access script variables.

[plata]

I got that part. I'm interested in the part where you use the script variable.

[ImperatorS79]

I just get the script._environment variable (in my new shortcut pr), to append to it the VK_ICD_FILENAMES variable:

Wine.prototype.DXVK = function (quickscript, dxvkVersion) {
    ...
    //Update environment to ensure the right GPU is loaded
    var gpuType = this.wizard().menu("Please select the type of your main GPU", ["AMD", "Intel", "Nvidia"]);
    var envJSON = {};
    if (typeof quickscript._environment !== 'undefined'){
        envJSON = JSON.parse(quickscript._environment);
    }
    if (gpuType.text == "Nvidia") {
        envJSON["VK_ICD_FILENAMES"] = "/usr/share/vulkan/icd.d/nvidia_icd.json";
    }
    else if (gpuType.text == "AMD") {
        if (this.architecture() == "amd64"){
            envJSON["VK_ICD_FILENAMES"] = "/usr/share/vulkan/icd.d/radeon_icd.x86_64.json";
        }
        else{
            envJSON["VK_ICD_FILENAMES"] = "/usr/share/vulkan/icd.d/radeon_icd.x86.json"; //To check
        }
    }
    quickscript._environment = JSON.stringify(envJSON);
    ...

Won't this cause issues if you do not use a QuickScript?
