Whoever did the first video (4K) really needs to invest in some rudder pedals. Just sayin'.
Edit: OK, I watched the second video as well. Maybe the rudders don't move in the 3D models? I don't know, it's just weird seeing people not counteracting the adverse yaw. I do like that jet efflux/heat distortion is modeled (finally!).
Edit2: OK, the rudder stuff may have to do with the game settings. Still, it's looking amazing. It will be interesting to see how it runs on my system.
