Already read it and that sounds like something the marketing department cook up. Not that it matters, I'm staying truth to what I believe, and what I believe is that this Demo probably runs better than anything else in the current build of the actual game. It is something that was released, it must had priority.

Episode Duscae is already something that was released, and was more fleshed out than this demo. It was actually a small part of the open world and it runs much better.  It was released. Twice. It must "had" priority.

Would episode Duscae run as good if it had many of the new technical features this demo had, which the final version will surely have?
