From the tech specs page:
"NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching"
I see no reason why it wouldn't in boot camp.
I doubt there'd be Optimus support in Bootcamp. Optimus support is something the manufacturer has to build into the laptop, and, as with the ATI solution before it (6750/6770) it is supported in OSX but not Windows.
