So what you are saying is that the Real Lights part actually helps? by limiting sounds and doing other things? i havent had time to check the read me yet, just wondering. thanks also for the posts and hte help.
Well, Real Lights (I guess :shrug:) might help in interiors where you're being bottlenecked by sound. Practically speaking, I don't think this would ever happen. However, I really don't think Real Lights will give you too much of an issue. As PetrusOctavianus said, it mainly affects interiors where you're just not going to see FPS issues. Also, you mentioned Illumination Within, I think. If you were asking about THAT functionality, then I misunderstood you. IW showed exterior windows lit/unlit (not light shining into the interior), and for that functionality I direct you toward http://www.tesnexus.com/downloads/file.php?id=19628.
