When it says at the end that the footage is directly from the console, it can never be rendered because now I'm not too sure about this but I think it's actually "illegal" to say it's in-game footage from a platform when it is pre-rendered. The gameplay trailer was exactly like the game we later got. The other trailers had no console indications unlike the gameplay trailer and this one. I don't see much room for bullsh*t here, the possibilities are endless, they're no longer as limited, especially on PC.
As for the wind, well, definitely basic physics, not real time.
