Color "Banding" Issues

I've had the problem shown above in the image link since SH3. Basically, all of my sky textures and light around the moon have this odd banding effect, which I have been unable to get rid of. I run the game on a GeForce 7800 GT, current drivers and maximum detail settings. Is there any way to get rid of that ugly banding as seen in that shot?

Well the picture is too dark to really see.

But yes there is some banding visible. It has to do with color palate depth.

There is very slight banding on the screenshot but are you expecting us to be EASILY able to see the issue?
