Sorry to piggyback onto this post , better than starting a new one and its to do with graphics anyway.
I have an ATI HD5770 1Gb DDR5 , I am no techie so what I say is a guess. When on patrol I was on the deck next to the deck gun (everyone does it at least once

) when I turned and looked up at the CT, sun was at my 180 not high and the P/scope housing and other shadows were showing through the CT.
Like the CT was near transparent , I guess this is not my card but part of the coding.
Are others seeing the same thing , no biggie , but its there ...
