It's possible that Star Blade only renders a few things, then "multiplies" it with the ASIC. Good example would be the asteroids. It might render two or three as "real" 3D and then use those as the source to quickly fill the screen with asteroids by scaling and rotating the few 3D rendered asteroids. The wireframe models are almost certainly rendered, not video. I really need to pick up this game... looks pretty cool!
