Hello, igd passthrough with intel nuc broadwell, skylake, kabylake works very well with windows OS. But, since a intel update igd drivers , > 20.19.15.4531 from 29/09/2016, ( we are using intel driver from intel site, not windows default driver ) just after driver installation, half of the ram of the OS is taken ( 4G for 8G Ram) as non paginated ram. With a native installation, this problem does not exist. Any idea ?
