After opening FSX, If I click on a `saved flight` it can take yp to 4 or 5 minutes before the small windows opens to show Loading activity and I wonder if this is caused by the large amount of scenery I have installed or could it be something else.Once the flight is loaded it runs just fine with good FPS.Appreciate your thoughts- guysThanksGeorge

The loading time can of course increase due to a larger amount of addons that are used in that saved flight, but I must admit 4 to 5 minutes are rather long. When the window showing the loading activity appears, is the loading process already started or does is start only then?

To load a flight can definately take some time depending on the addons you have, but if you are just saving a flight that should be almost instantaneous. Saving a flight should not take 4-5 minutes as you descibe.

Photographic scenery can take an age to load and a high lod_radius setting can also greatly increase loading times as can most addons to some degree.IAN

I believe FSX reads ALL your scenery addons, everytime you startup, even if they are active or not. To prove that create a 'dummy' scenery area in your scenery.cfg that points to nowhere. Then activate it and see if FSX questions it, then 'deactivate it' and again see if FSX questions it.. One of the major slow downs is the amount of addon aircraft that you have installed.One way I have found in reducing the scenery loadtime is to use this nice program by Andrew Thorton. great support by Andrew BTWWhat does it do:1. Allows you to repair errors in scenery.cfg2. Allows grouping of scenery files (eg Europe, USA, etc)3. Allows very easy to change scenery priorties either individualy or by group.4. Allows you to active only the scenery that you want for you flight (ie just Europe)5. reduces loading timesThe link:http://sourceforge.n...sceditor/files/

Yes. This is where an SSD speeds load times about 10x WRT a HDD.Cheers,- jahman.

No, that is not true. FSX creates a database of active scenery that is sorted by lat/long, so that only scenery within the area of the viewport is opened and loaded. The main outlayer is for object libraries, which have global scope. Install procmon and monitor what files FSX is accessing while loading and you will see.It is true that FSX will go through gauge .gau or .dll files on startup. That isn't dependent on loading any saved flight though.scott s..

I wish!Even if I start my flight in some South Pacific atoll, FSX takes 12 minutes to start. This start time seems fairly fixed independent of location, so I would presume all scenery directories are being scanned.Also folks lucky to have SSDs for scenery report a 10x speed-up FSX load times, further supporting what seems like FSX scanning all scenery folders.Cheers,- jahman.

So I looked up the scenery numbering map, then unchecked those that did not apply to the Washington area (OrbX PNW / NRM)At the initial load it too 1:20 to the spinning aircraft, then 2.00 to "Ready to Start". I killed the session and restarted the pc, timing it again: To the spinning aircraft - .25 seconds: to "Ready to Start" - .50 seconds. Here's the map. The numbers across the top are the first pair in the scenery list, with the side being the last two numbers. http://dl.dropbox.com/u/52676345/Scenery_Numbering%20Schema.xps

Thanks for this info - I have installed the scenery.cfg programme and it reduced my 4-5 minutes to less than 1 minuteCheersGeorge

One of my online friends suggested that he and another gentleman had experienced "issues" when applying groups which included the OrbX sceneries, so that might be something to keep in the back of one's mind.... :(

Out of curiosity, I loaded FSX with Procmon (and about a dozen other apps running) and started a free flight in the default C172 no weather at PKMJ. Took 31 secs on SSD. I then looked at the file access data for fsx in procmon, and here are the largest users in terms of bytes read (not sure if just opening a file or reading bytes has biggest impact though). I was surprised by Aerosoft antarctica X. Not sure what's going on there.Here are the biggest hogs:All in Mb readAntarcticaX 462sceneryworld 87scenerybase 34ORBX 34UMKK Khrabrovo 29sceneryglobal 18FSG World mesh 16City of Aarhus 15FSG Canada mesh 11for comparisonairplanesC172 7.6So there are a couple scenery areas which are the "bad actors" when it comes to reading file data.scott s..

Another one of those things that makes ya go "hmmmmm."Were your last or very recent flights in the vicinity of UMKK or Antarctica? Were those sceneries recently loaded? I think getting to the bottom of what's being loaded by default might make a tailored solution for improved loading (i.e. second-level disk cache, preemptive loading etc) possible.

Dont use this program if you are running any ORBX scenery as it will cause issues as they both write to the same scenery cfg file
