Afcad
This is being worked on, the FSX version will include all the latest developement from the FS9 versions made by Harpsi (and all the others the helped him with suggestions)
flickering textures, bleed though
There are no flickering textures, and nobody reported it so far. The bleed patch was for FS9 only, FSX version doesn't have this issue.
Unless you are referring to the flickering of the Las Vegas buildings, that happens when scenery shadows on ground are turned on, but that's a bug of the default scenery (and it happens everywere) those buildings are not part of our scenery.
Or, you are using DX10, which flickers also on the default scenery.
acropolis effect
This shouldn't be an issue in FSX, because in FSX we DO provide a small local mesh to smooth out elevation differences. However, if you have another mesh with higher resolution, it will always show up. What do you have installed ? And, how do you set your mesh complexity slider ?
jetway head not turning all the way.
This is not related to the scenery. The jetways just have control bones, but it's FSX that moves them independently.
Problems like this and also issues like jetway wheels going into the ground appear also with the default jetways on the default scenery, (it's just that people dont' usally fly the default sceneries), and the effect changes depending on the airplane, and it's not something we can fix, unless we replace entirely the jetway system, which is something we are considering to do.
