Hi Jim,My compliments for the trouble you have taken to help this guy out. There are several other members who also behave like this and are an example to the rest of us. Well done!Mike

My advice is to look at the pinned information thread at the top of the forum and try those changes first to the FS9 config file. If you are unsure of what BIOS is, then do not get into the innard workings of your computer you could give yourself a lot of grief. You may want to get help with that!I got FS9 the day of release and it has taken me until last week to get it to the point where it will average 15-18 FPS. Now I can turn of the evil FRAME RATE COUNTER and fly for a change. I now have a sim and not a tweaking program.Take heart and if I could do it you can too! Stick with I pretty happy at this point and have two Payware addons working fairly well at this time.Tony

:-shy :-shy Awww shucks. Thanks for the kudos Mike. :-shy :-shyJim :)

Thomas,I have seen The 3.8 should be released by october 8th...

Tomas, some advice about the Swedeflight Pro scenery. I was having the same problem you describe when I brought it into FS9. I discovered that if you get rid of the landclass scenery addon and just do the airport it works much better.Lee

Hi Lee!Yes, I've gotten rid of EVERYTHING in my FS9 at the moment. The only addon I'm using is ESSA, Stockholm, Arlanda airport and it SUCKS! I've got all, and I mean ALL my sliders in FS9 set to about 10%. My flightsimulator looks really really really bad but when I'm approaching a small not so busy airport I've got framerates like 47-52! But when I'm approaching ESSA, ooohh yeah! The framerates drop to 2-4, the computer freezes for about 5-7 seconds until the computer is all finished with building the airport building by building...Guys, I think I'm all done with Microsoft Flightsimulator. After seven years of flying MSFS I'm fed up. I don't have the strength to continue messing around with this framerates ####. About a week ago I bought PSS Airbus 330-200 and 330-300. And you know what? It was soooabsolutely brilliantly bad! My framerates dropped to 7-9 at London, Heathrow with all sliders as mentioned above. And my specs? Oh hahaha!Not so bad, look:Pentium P4 3.0 Ghz1024 RAMRadeOn 9800 128 MB 3.6/3.7 CatalystFSUIPC 3.08/Tomas

Hi JimOnce again, thanx for your hints.I tried each point you mentioned in this thread, one by one, including new BIOS, new Catalyst driver, FSSound1.6beta, all sliders to the left, etc...The result is: nothing has changed!I made these tests at EDDF with Simflyers addon scenery. Looking to the east, wait till everything is rendered, then looking to the west, many AI aircrafts are greyed out and texture patches are black.Wait again about 5 seconds for rendering. Looking back to the east, same results, same procedure. Switching back and forth between east and west, I have seen that allways the same ACs or texture patches are turning to grey/black, all the time...The point is: the same behaviour is occuring at smaller addon-airports also.I think, the "problem" must be in the way M$ handles the thirdparty textures in FS9. In FS2002, no problem of this kind at all.I had a look at the ESSA airport mentioned by Tomas with the same addon package from Swedflight. Approaching with 24 fps then stutter stutter stutter during the rendering of airport textures (freezing many time for about 1 second) then 24-25 fps again while landing and taxiing around. This was tested with all slider maxed out, FSlandclass, broken sky.Not too bad but the stutter are anoying.Let's wait for an hypothetic patch for FS9 or a magic driver update for the Radeon...

Hi Jean-Claude,Well, crap! After all the time I spent trying to think of everything I could and posting it I was sure hoping SOMETHING :-boom would help you guys out. What about the suggestion Lee gave on not using the landclass that came with this third party addon? Of course, I cannot help too much with third party addon bugs. But as I said I sure was hoping something here would help. Have you got all the latest WinXP updates installed? Are you using any USB devices? Have you seen the following thread?http://forums.avsim.net/dcboard.php?az=sho...&mesg_id=148334Well, lets hope for one of those magical items you mentioned, a patch and the ATI driver update. The only other thing I can think of for you to try at the moment is to rename your FS9.cfg file, let it rebuild itself from scratch, and see if that does anything. If you don't like the results you can always delete the rebuilt one and rename the old one back to FS9.cfgJim

Thank You very much anyway, I learned a lot, reading your informations.I switched the Landclass off, regenerate FS9.cfg many times, everything you have suggested but no change.After installing the last USP Patch from MS, I do not know if it is just a subjective impression, but the sim seems to run a little bit smoother.(I never had trouble with fps, just drop down to 3-4 fps during rendering of 3rd party buildings or AI aricrafts.)Now, I just fly and try to ignore these stutters...

Rock On FS 2002...you guys are really spooking me as I have not yet purchased 2004. I have an absolutely jouful operation with 2002 with loads of add-on and FPS at 25 solid except Simflyers areas where thye drop to 15-18...which to me is acceptable...

Hi Salbado,Well, the first I thought the first month with FS2004 was alittle rough, but after a fix was found for the xml autogen bug(I consider it a bug anyway) and I have very close to the same performance in FS2004 you are having in FS2002. But FS2004 rocks compared to FS2002(if you ask me)! ;) I also have loads of addons installed, FSGenesis US Landclass and entire US FSGenesis 38 DEM Scenery, WeatherCenter 2.3.1, a number of Simflyers.net airports, RealityXP 530 GPS, Lago Georender 1 Scenery, Lago Venice Scenery, Wonderful Rio Scenery, and a great number of addon planes both payware and freeware. And FS2004 never crashes. So don't be afraid to make the jump to FS2004 when you think you are ready! :-coolCheers,Jim"Variable, this is EasyRhino. Do you copy? Over." Loud and clear EasyRhino.

If the basic sim isn't functioning to specs, why on earth would you expect it to work with "addons" that may not yet be optimized for FS9?As far as the slowdown in fps over time, this is indeed caused by FS9 not releasing memory after having passed Autogen scenery. The "short term fix" is to rename the "default.xml" file to something like "default.xml.bak" to disable that part of Autogen.BillAVSIM OmbudsmanFounder and Director,Creative Recycling of Aircraft Partshttp://catholic-hymns.com/frbill/FS2002/images/fartslogo.jpg
