I tried to install Intel driver same version without "patched" for HD 4600 and I run VK-Z 0.2.0 but it detects 1 device as GTX 780 Ti and doesn't support HD 4600.
How do I patch Vulkan for HD4600?
1) patch igdlh64.inf with Notepad++
CopyFiles=Vulkan.Copy , Vulkan.Copy32,
2) there is an issue in the runtimes giving all iGPUs the same device name: "GPU"
patch igvk64.dll and igvk32.dll with a hex editor
disable driver signature - secure boot off
bcdedit -set load options DISABLE_INTEGRITY_CHECKS
bcdedit -set test signing ON
disable driver signature - secure boot on
