um, i was thinking, is there any Dx11 only game?
i think that will not going to happen soon. there are still many people doesn't own dx11 cable card. at least the dev will not want to minimize their potential customer. that's also the reason dev go for the console to widen the target audience. to some extent they have dumb down the game graphic and gameplay so the console folks able to play the game with their limited hardware capability and controller. heck maybe before you can see dx11 exclusive title dx12 already come out together with windows 8
. by then if the console still the same as today you will see dev offering console port title to the pc with dx12 and dx9 flavor. people with dx10 or dx11 card will be forced to play the game in dx9
