Graphics settings resetting every launch when Vulkan is selected

[blueblaze]

Whenever Vulkan is selected for rendering, the game launches with 1280x720 windowed, with all graphics settings set to some other default option from what I had. It also appears to use DX11 anyway, having failed to launch with Vulkan entirely. Changing to DX11 resolves this but is only a temporary workaround as Vulkan is preferred
