The loading thing seems to be better. Now I have a strange light here and there (blinding light). I have seen other report this as well.
So, I have to opt out again (and now I stay out). This better get fixed.
Edit: I should add that the blinding light was in Corvega. I tested out some other ruins and the entire game is brighter, although not as extreme when you walking through some doorways in Corvega. I can't upload a screenshot but I think you know what white light through a doorway looks like (I have an AMD by the way, that may be relevant).
I hope that this isn't slipping through your testing.
