Feature Request

I confirm:

  • [x] that I haven't found another request for this feature.
  • [x] that I have checked whether there are updates for my system available that
    contain this feature already.

Description

On systems without Vulkan support, many games fail to run because DXVK reports no support for a given Direct3D level. As an example, on an Intel Sandybridge processor with Intel HD 3000 graphics, it lacks Vulkan support but WineD3D works well with the OpenGL 3.0 support. There is an environment variable PROTON_USE_WINED3D for this already, but most users would not find it first hand. Defining this automatically when we don't see Vulkan support will ease this process.

Justification [optional]

Proton uses DXVK by default, hence this is useful in Proton more than Wine

Risks [optional]

There could be situations with incorrect Vulkan detection, but we can always provide an override if that happens
