What missed was how to make it "seamless" when you walk or turn.
From what I see, they used 2 or 3 mid step view, ie rendering 3 steps between current and future position.
OK, I assume DMA is fully used here.

The effect seems better than SitD and we're on a SMS!
How the hell did they do this ?
Could it be applied to Genny ?
