Hi jgreth. I hate to call you out, hope that doesn't bother you but I am experiencing a minor problem with FZ02 Portland. It is beautiful scenery but I just notice a little stuttering. I can't really focus on the beautiful graphics of airport as I fly by. I am getting 19fps at worst. I just bought FS9 last night for this scenery so I know of no tweaks in the cfg except for what flightscenery suggested on their site. I don't know what that really does but I am assuming it helps with performance?? If you could list your software specs that you ran with that video you made I would really appreciate it. My hardware specs are intel core 2 duo (2.13 ghz) 1gb ram and a geforce 7600gs 256mb graphics card. Thanx for your time.

Try renameing the file in the 'Autogen' folder (C:Flight SimulatorAutogen) to something with an extention like '.bak'...There are still problems with the extra autogen FS9 uses over large city areas. Let us know if this helps. :-)

Did you install the FS9.1 update?http://www.microsoft.com/games/flightsimulator/downloads.asp

Let's put this in order:1. Install the FS9.12. Do what Chis stated above if your still having trouble:-)

Other than the fact that I replied to your message.... :(Follow the advice the others have stated here.There's also a Tips and Tricks forum in the FSX forum.

I thought you were trying to troubleshoot FS9??? :+
