I've heard the same thing in different ways lately about FS2k4. I just read a thread about Boeing versus Airbus where a user named WAD3 (Andrew) stated his PSS A340 which ran good at first now brings FS2k4 to it's knees. I'm having the same problem but with the sim in general... I used to think it was certain add-ons or AS2004.5 but that doesn't seem to be the case. FS2k4 ran well for many months but now is having the hardest time loading textures and is running slower in general. I don't know if this progressive decline in performance is due to my install of SP2 for WindowsXP but things sure are getting slower on my system. I have Viruscan running on my system as well which I didn't have before prior to SP2. I've run out of ideas. I now am required to use FSAutoStart to shut down unwanted services to get FS2k4 to run halfway decent.All in all I feel many seem to be experiencing slow downs in FS and point it to a particular add-on but is that really the case? How can an add-on run great for months only to start slowing down now. I can't figure out what's causing this. I have the FS2k4 update, I'm using FSW's clouds and even shut down the extra autogen objects despite Microsoft's promise to have solved that issue... I have no viruses or trogens to speak of (at least that's what my Viruscan software is telling me). I also have installed, Spybot, NoAdware, and Spywareblaster, all are reporting nothing. I also tried booting my machine with a virtual Windows Gui in order to check XP out without it actually loading to see if anything had crept in disguising itself as a valid executable, nothing was reported. If others are seeing steady slowdowns with FS2k4 maybe we all should put our heads together and see if there is a common problem. It makes no since to me that this is happening. I've found myself disabling most of my Simflyers scenery due to the fact it's now impossible to fly in and out of those airports without a slide show. I have more than enough horsepower so I can't understand this. All other applications run fine on my computer...I sure hope to here from others on this, take care..... :-hmmm

I've noticed my FS9 performance seems to be slowing down...... Used to be able to at least get my locked 25fps at CYWG (using the cywg v1.01 scenery) in the pmdg 737, now I'm averaging 15-20fps at the same scenery...... No idea why....

General overall slowdown here as well. I think it is probably either SP2 for XP or DirectX 9.0c. I don't wanna do a reformat to get rid of them but I may.

Between FS's SP1 and WindowsXP's SP2, I wonder which area would be the proper area to look into. Before these two service paks FS2k4 had stable performance...:-hmmm

If FS9 is gradually getting slower and slower, then something is giving this slowdown process a "memory". That is, the slowdown process is able to start from the last state it was in and get worse from there, then somehow save the worsened state as a starting point for next time you run FS9. Gradually failing hardware could provide this

Using SP1 and DirectX 9.0b, yet never have slow downs. Never had to reinstall FS9 or anything. I've only updated FS9 with the patch. I do use the tweaks that were needed when FS9 came out except for what the patch fixed. I turned off the indexing and stamping feature in XP and don't use the System Restore utility either. The only add-ons I have are as follows:PMDG 737NG 600/700/800/900PMDG B1900DFlight One Ultimate TrafficFlight One Cessna CardinalFlight One Piper MeridianFlight One ATR 72RealAir ScoutReality XP 530 GPS, Wx500, and Jetline 2 and 4EagleSoft Cessna Citation XFSUIPC 3.41 registered versionFSGenesis Landclass and MeshAnd an early set of cloudsMy computer is the same as well, no changes since I installed FS9.Pentium 4 - 1.8GHz Northwood1,000 MB RDRAMGeForce Ti4600 128MB VideoAbit TH7II MBSound Blaster Audigy 2CH Yoke and PedalsI am running older video drivers and haven't updated any drivers for months. Most newer video drivers didn't work or made things worse, and I have no reason to update other system drivers since things work fine. Besides Windows XP Pro, I only have a few programs installed that I use:Acrobat Reader 6.0Creative Sound-related programsEditVoicePackFSBuild 2.1 (reg'd)Nero 6.0 (reg'd)Quicktime (free)Smart FTP (free)Trend Micro Internet Security (reg'd)WinZip 9 (reg'd)ZoneAlarm Pro (reg'd)That's it! I have nothing else on here. I don't have any warez/pirated programs, as I won't use them. Not that any of you do, just mentioning.

Think that is the key...XP with SP1 and NOT SP2 and DirectX 9.0b, not c.

Neither.Your machine over time gets clogged with unused registry entries, page file congestion as your harddisk fills up, disk fragmentation, etc. etc.Add to that the ever larger number of programs that have some kind of background process activated constantly (taking up memory and CPU cycles) and your machine overall gets slower.As most software doesn't use your machine resources as completely as FS does you don't notice this normally, but when running FS that reduction makes it all run slower.Another factor is that you get used to what you have and start to want faster and faster.When you first got your computer you thought "wow, this is fast". Now you see computers with a lot more power in stores and start to consciously or subconsciously make up arguments to buy one. Seeing performance drops where there are none is one of those things.Personally I see little performance drop (if any) in FS2004 since I installed it over a year ago.And that's despite installing a lot of scenery (including 30 meter mesh) and aircraft and even increasing some of the detail settings over time.

but for interests sake, do you have XP SP2 and DX9c installed?Another culprit may be a bloated set of System Restore checkpoints. If you are going to re-install it may be worth ditching this history and seeing what happens.Andy b

HiHow do you disable Security center?Troy

Troy - Click Start then click Run. Type services.msc in the Open box. Click OK and then scroll down and double-click on Security Center. Select Disable in the Start Up option box.Doug

no, I use Windows 2000 which is subject to all the things I mention as is XP.XP SP2 however has no performance problems that I notice on my office machine (which of course does not run FS but does run several other memory intensive applications).

Yup that is how you do it. If you visit BlackVipers homepage it shows an easy way to make profiles. You may want that firewall otherwise to protect your computer even if it

Just a suggestion:Periodically rebuilding fs9.cfg does it for me.Happy flying:RTH
