After some tests i can say that they have reduced the range of rendering of the trees present on the hood.
The game will not make to see all you the trees that there are in the neighborhood, that will ignore the the parameter "clip", but many but many less . This limitation comes only applied to the trees.
It is known, Antennas, Parabolas, and objects particular as the beacons or the palaces will remain however visible, but you can forget also covered hills to you of plants.
the triangle represents the view camera, it's indicative just in order makes to understand you where I'm watching.
The trees marked in green are those that enter in the new range, while the once in red will not be never visible 'cause they are out of "tree-render-range", although the editing of LiveCamera.txt
another view..
another test..
at this point i don't think it's about an number of the tree but a range of camera, the game render the trees just when at the correct distance from the camera... or the used lot
so, if anyone know how to fix this frikin' limitation will be considered a new Hero
