But even Vue is in danger, every 3D rendering program out there that doesn't do realtime rendering is in danger because people aren't going to sit around waiting for renders when they don't have to.  I've seen it do Vue-type scenery and detail that looks every bit as good as Vue, and dare I say it better due to the talent of the artist using it.

Each frame took precisely one sixtieth of a second to be completely rendered, or in other words, it's realtime rendering at 60FPS and that's pretty damn neat!  You move around your scene like a game, and your render is done, whatever the view is, that's your render.  I doubt realtime rendering can be ignored by any 3D rendering product if intends to survive, I could be wrong, but seriously, I don't think I am, not after seeing what Unreal Engine 4 can do.
