I've seen this since release day, and after this many updates, I wonder if it's a game issue or drivers. All the nvidia drivers I've tried have the same effect, none can fix this for me anyway. I'm running a GTX560Ti 1gb and currently the 270.51 drivers because they work best with my other games.

As you can see in these two screenshots, there are places in almost every level where the lighting changes from a darker "indoor" type to a very light "outdoor" style, instantly. I say indoor to outdoor because that's what it resembles to me and would make sense if that's the effect SD wanted to achieve, (why it shows up indoors like this is beyond me). In playing the DLC maps today, I've seen places that do it as well. It's a shame because the maps look great, but this glitch is hard to ignore and play past because it happens so fast and abruptly, and is repeatable everywhere you see it. This example looks minor at a glance but there are many places in other maps where it really distracts from gameplay because it's so obvious. I've messed with driver settings a bit but nothing really improves it.

I haven't put any feelers out in the Nvidia forums, yet, just figured this would get more exposure to the devs.

If you've seen this, post what video card you were using, maybe it will help describe the scope of the problem. Thanks.
