You mean triple buffer vsync by virtue of it being windowed? It's still possible for an app to have traditional double buffer vsync be its own user setting.
I still don't have an answer for this either. It looks like it's just the Xbox Digital store - despite them saying 'participating retailers', no-one is offering a digital code with the free PC copy.
I'm curious how this deal applies to those buying the console bundle. The website says that it applies, yet the bundle doesn't come out until the 5th. Which digital codes need to be redeemed before then.
