Comment (by Gyan):

 Can reproduce with my build on Windows 7 but not on Windows 10. The former
 has a discrete Nvidia Maxwell 1 GPU (750 Ti). Vulkan API 1.2.142. Driver
 456.55. There's an access violation (c0000005) in nvoglv64.dll reported.
 The Vulkan Cube supplied with LunarG's Vulkan SDK works.

 These are the contents of nv-vk64.json


 {{{
 {
     "file_format_version" : "1.0.0",
     "ICD": {
         "library_path": ".\\nvoglv64.dll",
         "api_version" : "1.2.142"
     },
     "layer": {
         "name": "VK_LAYER_NV_optimus",
         "type": "INSTANCE",
         "library_path": ".\\nvoglv64.dll",
         "api_version" : "1.2.142",
         "implementation_version" : "1",
         "description" : "NVIDIA Optimus layer",
         "functions": {
             "vkGetInstanceProcAddr": "vk_optimusGetInstanceProcAddr",
             "vkGetDeviceProcAddr": "vk_optimusGetDeviceProcAddr"
         },
         "disable_environment": {
             "DISABLE_LAYER_NV_OPTIMUS_1": ""
         }
     }
 }
 }}}

 The (working) Windows 10 GPU is the on-die Intel® UHD Graphics 630.
