This could be connected to Anisotropic filtering.
When you look into that "dead end", you'll have a lot of textures at a steep angle to your point of view, and AF has a lot of work to do.

AF has never been enabled in anything but the tech demo; but good thought process.

Still looking for another explanation of that one, because I refuse to believe that the HPL engine doesn't understand visibility culling.
