Well there was a post a little while ago that showed nVidia drivers after 398.11 were also not passing metadata properly.

The thread below is a list of drivers and issues that people have reported.

So it may be a case of if you are using a later nVidia driver that may be the case and both Windows and nVidia are doing the same thing.
I use 385.28 as it seems to have the best feedback for most things working, but I also never knew the difference between working metadata or not, I only found this out due to this thread.
