      On a HD 530 (i7-6700k) DX12 support disappeared when running HD 530 as primary device. This is tested on Windows 10 x64. Is this a nasty bug or intended? This didn't happen in older 15.40 drivers. Because when running as secondary device it detects DX12 support as you can see below. Why doesn't Intel support DX12 with this driver when running as primary device? This driver is also hosted on Microsoft update page declared as WHQL driver!
