Ok so here it is I take of from KLGA bound for KPVD. I have UT at 95%, Active Sky weather, and flying the Flgith 1 421.. I have my FPS locked at 34 and from clearance to takeoff everything is smooth, no drop if fps maybe 1 the most. As I approach the airport in RHODE ISLAND (KPVD) things start changing. I get cleared for VOR DME 16 descent and at about 1000ft msl I save the flight for a later test. Once saved I continue my descent and my fps will be locked at 34fps but there will be this drop that lasts a split second (down to anywhere 20-26) causing the approach to stutter, even at 26+fps. Now when I load the the flight from saved flights Its the same deal. So I completely close FS2004 and restart FS2004 load the saved flight, 1000ft runway 16 in sight and descent is smooth as silk 34fps no drop, nada, not even 1 frame. Now I have the fs9.1 upgrade, vector objects=0 removed default autogen xml, pretty much every performance tweek in the book. I just formated my HD and FS2004 is the only game I have on the hard drive, I have 80gb of space and 9 is being used, and I defragment every day.. I even went as far as making FS2004 folder smaller, by deleting all scenery folders from pretty much evrywhere in the world except the easter United States, because thats the only place I fly, also deleted all default aircraft etc, which by the way did see some increase in smoothness and fps. SO why isnt evryhitng smooth from takeoff to touchdown, is this a know issue.My specs are a AMD FX55, with ATI X800 XT PLATINUM EDITION, (both watercooled) 2 gb of CORSAIR RAM, 2 SATA DRIVES in raid 0 running at 10k, SB AUDIGY 2 ZS with all the lates drivers. OW yeh and my awesome 25" Sony trinitron monitor widescreen, and the only resolution that fs2004 supports for this wide screen monitor is 1900*1200 and thats what I have to run otherwise everything looks unproportional.

i dont think its FS2004 per se it must be your hardware i.e your RAM sticks, if you have 2 sticks in there take one out n experiment n see if there is a difference.

What you describe is not a memory leak.If you lock your framerates at something less than unlimited (try setting it at 25 fps) then these stutters will disappear.If, after doing this, you still perceive stutters and/or less than optimal performance of the flight sim on your machine, you may want to consider therapy, especially if investing time and money in your setup has meant your children go hungry, interfered with normal life or work, etc. Good luck and best regards

If it were a memory leak you'd see highly increased pagefile activity, memory congestion, and other phenomena like that going on, memory moreover that would probably not be reclaimed when closing FS.And even then it is a memory leak, there's no telling from your account that it's FS.It might well be (and is in fact more likely) an addon you're running.I've observed AS taking over the CPU and having sometimes weird memory use, maybe that's the culprit?Or your shiny new photoscenery is overloading the scenery engine.

Hi,I guess every one has stutters to a certain extend.I have roughly the same system as you (only X850XT differs) but I occaisionally also have (tiny) stutters, that's just a part of our FS-life.About your Raid-0 (striping) configuration:I seriously would consider changing to raid-1, because with raid-0 you effectively have doubled your chance on disk failure.If one of the disks fails, the other disk also is useless. There's no way to recover that data.I have 2 SATA disks in raid-1 (mirroring) and it performs okidoki.My 2 bits,Egbert

that's the harsh truth, no matter your PC specs, you'll always have stutters...every PC equals in front of him :( :( :(

>that's the harsh truth, no matter your PC specs, you'll>always have stutters...every PC equals in front of him :( :(>:(>>>I primarily also fly with FS2004, but I tried X-plane and found it to be extremely smooth. It seems to me that Windows is to FS9 like Linux is to X-plane. That is the first is bloated and the second is streamlined.Lets hope that Microsoft does what needs to be done and actually matters in the next release. That is.... 1) overhaul the extremely dated graphics engine 2) improve the flight modeling to at least X-Plane responsiveness and accuracy. 3) overhaul the scenery system 4) build the support for MMOF (massively multiplayer online flying) to better support VATSIM etc instead of basing the multiplayer system on outdated dialup, serial, and lan concepts.

2 things. You might have some landclass in the wrong place somewhere. Go through your scenery folders and make sure all landclass files are in a scenery only folder with no texture folder with it. If this is not the case, this causes a memory leak and causes FS to grind to a halt. The other thing is get FSAutostart. A brilliant program. It shuts down everything not needed to run FS and streamlines your computer. I agree with the earlier comments. Find a comfortable place to lock your framerates for slightly smoother performance. On a high end machine 25 to 30 is a good range.Lee

"Memory leak", at least one meaning for this phrase, is easily detected: simply run Taskmgr.exe and watch what happens to physical memory over the course of your flights. I had a "memory leak" some time ago, from having a texture folder in the same folder my add-on scenery folder is in. It was pretty convincing to see my machine start out with something like 600mb of free ram, and watch it steadily dwindle down to none through the course of the flight. After removing this texture folder, free ram stablized at about 350mb free ram, no matter how long the flight.Noel

Thanks for all the replies guys I will give all tips a try. But the weird thing is like why when I save the flight at the approach point and reload it ,it doesnt make a diffrence unitl I completely restart FS2004 and then load the flight? This I guess means its gotta be something within FS2004 Folder itself right? Yes I shut pretty much everythng in the backround before running FS2004. I even load active sky ,dl the latest weather let it cache, input my flight plan and let active sky generate the weather into the weather engine and close active sky so i have no other programs running.

Did another flight today , with everything shut down in back round, and again is started to happen once airport was in sight, checked mem usage and cpu activity everything looked normal, physical memory stayed pretty much the same throughout the whole flight. So once it was stuttering, I cleared the weather still there , moved traffic slider to 0% still there, but once I shut down fs2004 restarted load the flight smooth again. I just dont know anymore looked at my scenery folders they all seemed in order, with the appropriate files. ANY OTHER IDEAS???

* This really sounds like the autogen bug...But you mention you've removed autogen.xml already. You've ruled out memory leak on your own my monitoring the memory usage in Task Manager. Even though the mem. use stayed reasonably stable, you still experienced a performance loss. * You mention you're flying to PVD - is this the new FlightScenery package, or default? (I have the new FlightScenery package, and either way - original or 3rd party scenery - have not seen this issue yet - PVD is my home airport). Does this ONLY happen to you from LGA to PVD, or is this a problem whenever you fly for an hour or so? * Do you see this with default aircraft, or only the Flight1 421?* AntiVirus software enabled? Perhaps disabling any AV software during your sim session may help? (mixed results on this tweak have been reported)* As mentioned above, remember that RAID-0 is a riskier setup than RAID-1. I have a striped setup myself, but I invested in an external USB2 hard drive which is on the receiving end of a daily dump of all my important documents and files. (eg: The master installers for my MSFS add-ons, my email and pictures, etc. etc.) Should a drive die on my array, all of my important "irreplacable" items are backed up. RAID-0 does not significantly impact speed within MSFS, but I've noticed some modest bootup and program loading times. MTBF on hard drives has improved significantly, so as long as you both know the risks of RAID-0 *AND* have a good backup setup in place, RAID-0 is not a problem at all. I'm at a loss!-Greg

I've been meaning to ask, are any 3-d clouds displayed when you're seeing this issue? If so, do you see the issue with clear skies or only a cirrus deck?There is one issue with MSFS's new 3-d cloud engine to keep in mind. Periodically, it deletes clouds outside of the draw distance range and builds new ones ahead. Fly out of KMFR headed south, and you can see the process in action about a half mile downrange. I see a slight performance decrease when this process happens. The greater your cloud draw distance, the more impact the drawing process has.Anyway, if you are flying with clouds, repeat this scenario with no clouds. If the fps falloff goes away, then try reducing your cloud draw distance somewhat.It's a shot in the dark, but it's the only thought I could offer.-John

if you have a texture folder in fs9/addon scenery folder then you get a memory leak, i ask this because in my addon scenry folder is a empty texture folder????regards rick
