While I was fiddling around with FSX using autogen I thought that perhaps building large autogen "exclusion zones" around the airport I was using might reduce the FPS reduction from autogen. I really like the vegetation around the airport but the FPS load throughout the Cessna flight is troublesome. So after building large autogen exclusion polygons around the airport, with better FPS, I thought that it would be nice if some talented person could create a process whereby the user could create an exclusion zone by merely clicking on the airport and a user pre-specified zone would be made and retained as a normal folder/scenery bgl. Thus favored airports would have autogen visible during operations.For me the process makes sense since, as I mentioned, I like some vegetation around the airport but want to reduce the hit. I do not yet know how close you can come to the airport with the exclusion polygon and still retain vegetation. By getting close you do begin to reduce the FPS hit even when there is autogen around the airport. Just thought I would toss out the idea to see if it makes any sense.

Makes good sense to me Dick. Over the weekend I revisited my scenery project of rebuilding my local airfield and the number of autogen trees and their placement are nowhere near reality. The road data used is fantastic, but the vegetation seems to be a blanket, one size fits approach for my area. I just ran across a new utility called someone is developing called "autotrees" in a design forum, which sounds promising. I definately agree performance gains can be made by reducing the amounts of "unneccesary" autogen and reworking placements.Regards, Kendall#1: [email protected]/Coolermaster HyperTX2 Gigabyte P35-DS3L 4GB Ballistix Tracers PC6400 EVGA 8800GT - 174.74 beta Seagate 250GB 7200.11 CH Yoke/Pedals/Saitek Throttle Dual Monitor: Dell 2405/1905 #2: Dell 8400 3.2 H.T. 3GB PC4200 - X800XT Diamond Xtreme/Logitech X-530's
