Enlighten falls under “pseudo-dynamic”, and has several drawbacks. First off, it’s hard to make major changes to a scene after the initial preprocessing steps. You can have different “states” of the scene for different cases (like a building being destroyed like you’d see in Battlefield, or a wall being destroyed), but generally it’s difficult to have fully dynamic worlds with Enlighten. There’s also problems such as it doesn’t handle rapidly updating light states very well - there’s usually some perceptually noticeable “lag” with the GI updating with respect to fast moving light sources, and similar goes for quickly changing light color.
It’s neat if your lighting changes slowly and you’re not going to have a lot of geometry changes going on in the scene in general, but otherwise it’s quite limited in that regard.
