Hm, I was wondering about that. I haven't tried this yet, just been reading through seeing what people think about it, and I'm wondering how exactly will this work together with things like darker dungeons and natural weather and the like? If it adds a post effect on your screen, won't it make things darker/brighter than intended? And won't it do pretty weird and funny stuff to fog and the like?
I use it with darker dungeons and quite honestly I love the combination.
I could probably link to some screenshots showing it in combination with darker dungesons if you're interested in seeing the results.
