Good evening...A longer time ago I was flown the Level-D into KORD and at about 5000ft, short before the FAF, I got a CTD, I thougt it would happen only once. But a few days ago, I flew with the NGX from KBUF (FlyTampas+US Cities Niagara Falls) to Fly Tampas Midway which I've bought a few minutes earlier and on the ILS of Midway I got another CTD. I did the flight once again to see if I can reproduce that bug and what shall I say, I got my CTD. The next try was with US Cities X off, and I won another CTD. The 4th flight was with KORD off and it works, I finally landed at Midway.What have I done, I made a deinstallation, downloaded the KORD Installer new and installed it. I guess I have it, but once again with KORD activated, I get the next CTD... I was not much away from throwing the computer out of the window, cause it's pretty boring flying the same flight ever and ever...Ok, I did the next try with AI Traffic off and on the ILS 31C on 1000ft I got my CTD. I've tuned the ORD VOR on Nav2 and I was 16.9nm away from the VOR when the CTD happens.So, Umberto (from FSDT) said that this could not have something 2 do with his KORD, because KORD will be loaded at exactly 10nm miles away of the airfield. But why did everything went fine when I switch KORD off?A strange thing is, that when I will start in the Chicago Area nothing happens, only when I fly into from anywhere else I got the crash.I've read about a man who's fixed his problem with a deinstall and reinstall of UTX USA. I don't want to deinstall and reinstall it cause I'm a bit affraid of destroying something like the textures in Europe from Ultimate Terrain Europe, or maybe Ground Environment will run into some troubles? Maybe someone has another idea?At present for the KORD area I've installed:- FS Global 2008- Ultimate Terrain USA X- Ground Environment X- US Cities X - Chicago- FSDT O'hare- FlyTampas Midway- and the Ultimate Traffic 2 with 50% AI Traffic

Unfortunately this CTD does not happen to everyone, maybe just you. I had a similar problem with KSEA. I could reproduce the CTD 100% of the time flying into Seattle in the PMDG 747 with the FMC programmed. If the FMC was not programmed and I flew it in manually, no CTD. If I changed PNW Scenery to the default, no CTD. Turn on PNW, CTD. It only affected the PMDG 747 and, so far, the 737NGX has had no issues. Since the PMDG 747 and the 737NGX use the same NAV info, I think the problem lies with the 747 but no one else has reported this problem (through extensive searches). It could be the PNW AFCAD but then, why doesn't the 737NGX crash too? I use MyTrafficX and place that far down in the scenery library so that any addon scenery's AFCAD will override the AI Program. Did you have an error in the Event Viewer? I had one indicating the Exception code 0xc0000005 (memory exception error) and no offending module. I recently reinstalled the PMDG 747 so I'm going to try flying into the PNW again and see if I can continue to duplicate the CTD. When you installed KORD, did you have UAC disabled and anti-virus software disabled? I would not discount FlyTampas Midway as an offender as it is all in the Chicago region. With my PMDG 747 going into Seattle, I got most of my CTD's as I crossed the mountains and Seattle came into view. Sorry I don't know of any magic bullet to fix your problem but hope this analysis helps in some way. Best regards,Jim

Change 1: After reading some threads over at the FTX forum regarding CTD's in that region, I attribute my CTD's with the PMDG 747 to lack of resources. KSEA and the Seattle area is known to take up excessive resources and that explains why I don't get the crashes when I switch to the default scenery. In your case, this explains your crashes too. Lack of resources when using commercial vs default scenery/aircraft. I know KORD takes up a lot of resources. I have FSDT's KORD and FlyTampa's Midway too and know the frame rates drop when in that area but no CTD yet. Best regards,Jim

Hmm don't think that it would be a problem of my resources, the computer handles JFK and Manhattan X, or Flightbeam SFO and the US Cities X - San Franciso, too... And at the time of my first crash, Midway wasn't realeased, so it was only KORD and the Chicago City. I'll will fly the next flight with UT USA off and take a look what is happening then... Guess that'll be an easier way than uninstall and reinstall the whole UT. But thank ya very much for your ideas.

"I've read about a man who's fixed his problem with a deinstall and reinstall of UTX USA. I don't want to deinstall and reinstall it cause I'm a bit affraid of destroying something like the textures in Europe from Ultimate Terrain Europe, or maybe Ground Environment will run into some troubles? Maybe someone has another idea?" One of the reasons why uninstalling and reinstalling UTX might have fixed one persons CTD's is the fact he had too many features of UTX turned on taking up a lot more resources. When he uninstalled/reinstalled UTX, things went back to the default and that's why he had no more CTD's. You may have a powerful computer but FSX is more powerful. Chicago City really takes up a lot of resources. If everyone who owns KORD, Chicago City, and Midway (like you and me) and had CTD's, then I would agree there's a problem with the scenery but that's not happening. Unfortunately, IMHO you'll have to reduce your sliders to gain more resources when flying in this area. Best regards,Jim

Hi and sorry for the late answer, I've had a litte less time in the past few days.Today I made another 2 flights, here are the results.I've edited my fsx.cfg and turned down a few settings and I've visited Bojotes site and looked for some tweaks. I made the first try and have the frames on to see if the computer will have any problems, but nothing 20 frames and more on the ILS 31C KMDW. 17nm away of ORD VOR, I got my good damn CTD. I guess, 20 frames must be enough and shows that my system has no problem in handling the scenerys. Other scenerys like KJFK (FSDT) in combination with Manhattan X (Aerosoft), or KLAS (FSDT) with US Cities X - Las Vegas (Aerosoft) or even KSFO (Flightbeam) with US Cities X - Frisco (Aerosoft) are running well. So I won't believe that my system can't handle the workflow.The second unmarked all Ultimate Terrain Entrys I've found in the scenery library and again, at exactly 17nm away of KORD I've get my CTD...When I turn off FSDT, all is fine... So I've let it off now until someone find the failure.Here is my new fsx.cfg and I'll show you my scenery.cfg, maybe there is a failure in the sorting of the layers?fsx.cfg:[AContain]LabelColor=FFFF0000LabelDelay=2000ShowLabelAirline=0ShowLabelAirlineAndFlightNumber=1ShowLabelAirspeed=0ShowLabelAltitude=1ShowLabelContainerId=0ShowLabelDistance=1ShowLabelFlightPlan=1ShowLabelHeading=0ShowLabelManufacturer=1ShowLabelModel=1ShowLabels=1ShowLabelTailNumber=0ShowUserLabel=0[ATC]AutoOpenAirTrafficWindow=0COMM_MSG_AI_ATC_COLOR=FFFF7840COMM_MSG_ATC_AI_COLOR=FF00FF00COMM_MSG_ATC_USER_COLOR=FFB6FFB6COMM_MSG_NONE_COLOR=FFFFFFFFCOMM_MSG_USER_ATC_COLOR=FFFFD21BPilotVoice=0ShowATCText=0UsePilotVoice=0[CONTROLS]Controls_Current=StandardControls_Default=StandardKBDAIL=64KBDELEV=64KBDRUD=64[Display]ActiveWindowTitleBackGroundColor=0,28,140,64ActiveWindowTitleTextColor=255,255,255BLOOM_EFFECTS=0ChangeTime=2.000000InfoBrakesEnable=FalseInfoLowerLeftBackGroundColor=255,0,0,128InfoLowerLeftTextColor=255,255,255InfoLowerRightBackGroundColor=255,0,0,128InfoLowerRightTextColor=255,255,255InfoOverspeedEnable=FalseInfoParkingBrakesEnable=FalseInfoPauseEnable=TrueInfoSlewEnable=TrueInfoStallEnable=FalseInfoUpperRightBackGroundColor=0,0,0,0InfoUpperRightTextColor=255,0,0NonActiveWindowTitleBackGroundColor=24,33,87,64NonActiveWindowTitleTextColor=255,255,255SKINNED_ANIMATIONS=1TEXTURE_BANDWIDTH_MULT=40TextureMaxLoad=30

I thought you had FlyTampa, UTX, FSDT scenery installed. Should be located somewhere after Area 115. Did you install them all into your AddOnScenery folder? I have never heard of that. That could be the problem as the installation(s) may have gotten corrupted somehow. In any case, I see nothing wrong with your FSX or Scenery configs that could tell me exactly why you are having CTD's. I still have doubts your system can handle the loads put on it by FSX. As I mentioned, my system can't handle FSX in the PMDG 747 in and around PNW Seattle when the PMDG FMC is programmed. All other aircraft I have tested can. Good luck. Hopefully someone else can pinpoint your problem. Best regards,Jim

Hmmm, not the whole scenery.cfg is shown but I pasted it. Maybe a limit in letters? Who knews? I've wrote my problem in the Ultimate Terrain forum, too and it looks like Ultimate Terrain is the problem.I don't need to uninstall it for testing. Within UT USA there is an option for quick enableing and disabling UT they've said and I disabled it. Touch and go in Midway and finally landed in O'Hare... The problem must be UT USA. Now I wait what the guys will tell me next to do.

UTX needs to be located just above Propeller Objects in the Scenery Library. Having it higher will trump out any commercial scenery below it and that could be your problem. Good to hear you almost have this problem fixed. Best regards,Jim

I'll give that a try tommorow. Thanks for that idea.
