I know it depends a lot on the game, some are perfect and some just fail 
due to insufficient support.  Dual booting between Windows and FreeBSD 
solves that.

Running Windows and keeping the FreeBSD daemons running requires 
overhead.  Overhead would be better than a dedicated second computer.

Ideally I'd want the server processes to continue running.  It operates 
as my IMAP and NAS server primarily so it's nothing intensive but I'd 
prefer to keep it running.

Maybe I worded the dual boot idea poorly.  I want the computer to dual 
boot between Windows and FreeBSD.  I want the FreeBSD drives to boot 
seamlessly between booting in Hyper-V and directly on the computer.
