Microsoft came up with a Firmware update. Updated in Windows 10 (my Boot Camp drive). Seems to be recognized better now. Still no luck with Aspyr games.
I'm pretty sure I've decided to become a Windows gamer. I got a GeForce Now account to hold me over until my Shadow server is ready (in December).
I'm thinking my next Apple computer will be a Mini with a hugh monitor.
Going to do a Search here to see if anyone else is using Shadow.
