Hi there. Hope someone can figure out what's going wrong all of a sudden with my FS9. For a start FS is taking an absolute age to boot up. The splash screen seems to be on for ever. In Windows Task Manager it shows that FS has stopped responding...but after a while it suddenly pops into life again and the entry screen appears. I've read that this has something to do with the number of aircraft you have in FS. Well, I don't really have a huge hangar going on here, so I don't know about that.Then when I choose my airport and go to fly FS seems to hang. For the default KSEA it's not so bad. But if I go to any of my add-on sceneries it takes an absolute eternity to load the scenery objects and terrain...and I mean an eternity. :( I was attempting a flight from EFTU to ESSB (Turku to Stockholm Bromma) and I simply could not get FS to take me to my starting point. I tried it several times and it hung every time. On one occasion I waited to see if it would free itself, but after 10 mins it was still showing 0% at loading scenery objects.Now I could consider whether there is a problem with my EFTU scenery. And that may in part be true. But even well trusted sceneries like ESSA (Stockholm Arlanda) are also taking a very long time to load. They don't hang completely but take much longer than they used to.For your info my system is:Windows 7 64 bit Home PremiumDirectX 11FS9.1 (with "No CD" patch)Dell Studio XPS 8000 (Intel Core i7 860; 640 GB Serial ATA HDD; 4 GB DDR3; 1 GB nVidia GeForce GTS 240; Realtek High Definition Audio; Dell 22" P2210 widescreen panel 1680 x 1050)So you'll see I have plenty of PC grunt.In addition I am running:Real Environment Xtreme FS2004Ground Environment Pro for FS2004Active Camera 2004I am running FS9 and REX and GE Pro as administrator.Can anyone please give me any tips on what the problem might be? I spent 2.5 hrs trying to sort this out this morning and eventually had to give up. Not a happy chappie... :( Thanks everyone. :(

That's a very similar system to mine, same CPU, RAM, HDD, and OS (except I use 32bit), but different graphics card. I'm thinking maybe you should try disk defragment. Are you getting good framerates after everything loads? That might indicate a file system problem.

I guess I could try defragging, but the PC is only a few months old. But I'm getting very high framerates once the sim loads. Mid to upper 40s and even mid 20s flying through dense high definition clouds from REX. What kind of file system problem were you thinking of?I've noticed that my Kaspersky Internet Security 2010 is quite active while I load FS. Is there a chance that KIS is the culprit here? Could it be noticing and monitoring the file activity going on as if were viral in nature? If so, any ideas what I can do to stop KIS doing it? (I'm asking this because KIS seriously slows down unpacking Winzip files, so I wonder if I'm seeing a similar phenomenon here?)

Hi Adrian,that sounds reasonable. Antivirus programs have a tendency to slow down system operation, especially if they're set to check every access to every file. And FS reads loads of files... Maybe just try completely disabling the program and see if it gets better. If it does, then you may want to check the settings for KIS, usually they have some possibility to explicitly disable monitoring of particular directories. Just a guess though, as I don't have that program.If that doesn't help, you could also try to run Sysinternals Filemon to see which programs are accessing which files, maybe that gives you more information.Ooops, just tried to find a link - filemon was obviously merged into a new program called "process monitor" which I didn't have a chance of trying out yet, but... just get it from here: http://technet.microsoft.com/en-us/sysinte...s/bb896645.aspxHTHChris
