I would just like to note that I have found ENBSeries 0.76 Generic to work quite nicely with Dreamfall The Longest Journey.

What works: Bloom and SSAO.
Bloom needs to be turned down from default, around 10-12 is a nice value for day, maybe 5-7 for night.
Ambient Occlusion works well with default values, and adds much needed shadows to plants for example.

What doesn't work: Reflections. Turning on Reflections in ENB causes black textures on many objects.

The graphics may appear slightly more saturated when running ENB, but I think it looks quite nice.
