The whole video is pretty damn sweet. I know there are so many factors that do not make this possible for a game that involves such a large world.
Hoping there will one day be a game like take on helicopters with this much detail.
At 2:22, the way the vegetation reacts to the rotor wash is absolutely mesmerizing!!!! It really gives that feeling of power that the helicopter really deserves!
I know I'm dreaming, but another 10 years and maybe I'll be flying helicopters on my pc in environments similar to this tech demo!!!
