The above image is how the DS9 corridors have always looked on my screen since dx11 support was added. I'm using a GeForce 8800 GT.

In addition, I've got these images to share of the black spots in the TOS corridors

Also, and I'm not sure how well you can tell on this image, but there is a triangular blacked-out area on my Advanced Escort (Hephaestus lower hull) "shuttlebay/vent/whatever" that is normally illuminated by the AEGIS shield effect.

Seems like a hard call to tell which mode I want to play in. With DX11 turned on, I have improved framerates and the textures that DO work are awesome.... but there are a few spots where the textures just aren't there at all and is pretty jarring. With DX9, slower framerates and the textures don't look quite as nice, but at least all the textures are there.
