By 'static images rendered in real time' I meant static images (characters not animated) rendered in real time (all 3D rendering occurring at 30+ fps). Myst consisted of pre-rendered images which is quite different.

It is possible to render 3D images of humans in real time on current consumer level 3D hardware that has moved beyond the uncanny valley when viewed as a static screenshot (from a real time rendered sequence) or as a Matrix style static scene / dynamic camera bullet time effect. The uncanny valley has not yet been bridged for procedurally animated humans. The problem is no longer in the rendering but in the procedural animation of human motion.
