It's worse for me. If I shutdown the Rift after a session, the next time day it won't work.
It takes forever for the HMD to turn on. I finally hear a beep from Win 10 then I hear another beep and it disconnects and goes black. I have to reboot to fix this.
This only started happening recently--maybe a week.
I'll just live with it and reboot until it's fixed. I'm afraid to rollback. It could make things even worse.
