KEYWORDS: FSX | default.xml | autogen fix | FPSHi all.A trick to increase FPS in FSX is to delete or rename the default.xml file found in the Autogen folder. It works.What it does is it removes all the added value random autogen from the sim ( burger joints, shopping malls, light poles... ). Unfortunately, it also eliminates many trees and shrubs in the process, leaving a slightly barren look to the sim.The default.xml can be altered to remove all the added value objects, and still allow randon trees and shrubs.The objects are arranged in classes, and while the GUID must be maintained for the classes themselves, the GUIDs for the objects can be dummied: <CLASS> <NAME>z_Rural Vertical Storage 20x20</NAME> <GUID>105a1663e16846e4b3b83ff61fa1dc3a</GUID> <WIDTH>20</WIDTH> <DEPTH>20</DEPTH> <LIBRARYOBJECT> <NAME>AG_USSilo01</NAME> <GUID>00000000000000000000000000000000</GUID> </LIBRARYOBJECT> <LIBRARYOBJECT> <NAME>AG_USSilo05</NAME> <GUID>00000000000000000000000000000000</GUID> </LIBRARYOBJECT> <LIBRARYOBJECT> <NAME>AG_USSilo03</NAME> <GUID>00000000000000000000000000000000</GUID> </LIBRARYOBJECT> <LIBRARYOBJECT> <NAME>AG_USSilo02</NAME> <GUID>00000000000000000000000000000000</GUID> </LIBRARYOBJECT> </CLASS>Done for all classes, this results in all random objects removed, but does not loose the trees. They, in turn, can be limited by the FSX.cfg entry:TERRAIN_MAX_AUTOGEN_TREES_PER_CELL=1000...entered into the {TERRAIN} section. The number can be lower for CPU-limited computers ( such as TERRAIN_MAX_AUTOGEN_TREES_PER_CELL=200 ).Dick

Well, I was right the first time...Try this in the {TERRAIN} section:TERRAIN_MAX_AUTOGEN_TREES_PER_CELL=1000 //4500 defaultTERRAIN_MAX_AUTOGEN_BUILDINGS_PER_CELL=3000 //3000 defaultIf you go low, like 20 for the value, it really works!Dick
