It’s rather interesting that I seem to have a fix for a problem that strictly speaking doesn’t exist!
Here is default London at night with the latest fix that I am testing.
And this is what default DX10 shows. Spot the difference!
Clearly the Dome is missing, several buildings at canary wharf. Also I don’t know if the resolution of the web page is good enough but if you can zoom in you will find that all the bridges including Tower Bridge and missing along with the London Eye. Now this sort of issue is always attributed on forums to DX10 “missing night textures” – which is odd when you think about it because if there were missing textures then the buildings would surely appear white/blue?
