Hmm, I don't know about that.

I'm not sure exactly what algorithm these game engines are using. (I bet 
Warp would know...) But I often notice that as the camera moves, certain 
objects leave faint "trails" behind them. It's as if the lighting 
approximation is doing some sort of iterative improvement, one iteration 
per frame. So the lighting converges to the correct values, but only for 
stationary images.

That's not quite "real-time". Close, though...
