Long Loading Times and Orbx Scenery

Recommended Posts

A sudden jump in my FSX loading time (initial load with a fresh PC boot up) recently shot up from 2 minutes as normal to a whopping 9 and a half minutes. I aleeady had FTX England, Scotland and Wales installed, but prior to the new loading time I had just installed Orbx's PNW and Northern California. I assume these a responsible for the jump. After switching these two new sceneries off on the sim and removing the folders from the FSX root directory, I am back to 2 minutes load time.

 

Now I don't know how to proceed. Put just one of the sceneries back in and fly it first.... swap out my UK Orbx sceneries for the American ones .... try both the US sceneries again, see if the remove-add has any benefial effect ....

 

The UK is my main flying area, but I fancied some nice Orbx bush flying with the Caravan, Islander and Twin Otter ....

Anybody got any other suggestions? A 9 minute load time is livable, but sometimes one of my screens can freeze and I occassionaly have to restart the computer and sim. Then another 10 minutes load time just to get back intp the flight feels like forever.

I think I may try a defrag using some third party software, see if that eases the problem. I may also switch off my antivirus, see if that has any effect.

9 min is excessive... Something's up.... Hmmmm

 

Rebooted the PC lately? Try running the Orbx control panel.

A reminder also to see that you have checked "Empty Scenery Cache on exit" in the settings/ scenery library section.

Ah, will do.

I have seen other posts where folks have lots of Orbx scenery, and they don't mention overlong loading times. Im hoping there is something else at work.

I've a lot of OrbX sceneries both in FSX and P3D which each weighs 190 Gb, without this nightmarish loading time. I've, of course, the infamous 6% pause which gets longer everytime I buy something new. Both are on a SSD.

 

This being said, on a laptop, my FSX has taken an eternity to open after I loaded 100 Gb of mesh and I strongly suspect a botched defrag by a program supposed to be smarter than the default defragger,

After installing ALOT of ORBX scenery I also have long load times, maybe 5-10 min. And that is with the fastest computer you can build (basically).

You can do a tweek to add an entry disable preload, but then it will just take longer once you select your flight. I was hoping someone would figure a fix for this also. Every computer w/ lots of ORBX will experience this (all the ones I have built).

I've found that the Orbx stuff does increase the loading time quite a bit. It's not other scenery in the library or aircraft. I guess that's just the price you pay for all the eye candy. :) But almost 10 minutes does seem a bit much.

I have all the Orbx sceneries except for a few EU and AU airports along with Global and Vector.  I also have all the Return to Misty Moorings sceneries and their shipping ai.  Add to that Aerosoft's Maldives, Seychelles, Madeira, Tahiti, and Balearic Islands.  I am using Ultimate Traffic 2 for my ai.  It all takes up about half of my 500GB SSD.   My Pilot's Global Ultimate mesh (101GB) is installed on a separate SSD.

 

I boot up to a saved startup flight directly from an icon on my desktop bypassing the FSX startup screen.

 

I just timed my startup with a stop watch.

 

The first startup after turning on my computer has a load time of 4:32 including 76 seconds at 6%.

 

Subsequent startups after the first one are about 3:20 including 48 seconds at 6%.

OK now Im curious, I will check the actual time and report back.

OK so with the disable preload added. It took 20 sec to boot to the startup screen. then after I select a flight it took 4:36 to load.

So if someone is using a mechanical HD I could see it taking 10min. to load, as I am using a Very fast Plextor M5Pro to achive this with LOTS of ORBX scenery.

Just a thought, if you are using global mesh like the gargantuan FSGlobal Ultimate mesh that covers the whole planet and have all of it check marked in your scenery library, load times will increase massively.

Just installed FSX-SE on SSD clean , fast loading with default. Installed PNW now with CentralV3 i got the infamous 6% pause for 1:45 minutes so the full scenery loading is approx 4 minutes.

If i remove PNW all goes back to 'normal'. I will install my other orbx stuff and will check. Of course its not so slow just a huge jump but looking at the experience i get with PNW worth it :)

The more scenery you have, the longer will be the 6% pause specially if these products contain mesh. There is only one solution to that : a SSD. I run P3D, not FSX-SE, but 1'45 seems a bit longish for PNW. Is your HD defragged ?

Hi I have SSD 500GB only for FSX everything smooth, im getting good framerate so no complain but the loading time was a bit strange i had normal hdd in my older config so i saw lot of long loading time but i thouhgt with a new config new ssds i will see better loading time but looks like not with Obrx:)  Of course 2 - 4 minutes not that long, My non simiulator game with 4k textures and massive visual stuff loads 1 minute:))) 

 

I saw some post about this 6% stuck and the guy talked about some texture mip map issue but i dont know all the details.

I have OrbX only on my FSX install. I use FSX Steam for everybody else's scenery. That solved the load times for me. I had the 10 minute load time when I had everything in FSX.  I just switch, depending on where I fly.

I use SimStarter NG and load things I want to load by region...just select the areas I want and nothing else gets loaded.  I have the following regions:

  • US East
  • US Central
  • US West
  • Europe
  • Pacific
  • Caribbean
  • Orbx Vector

If I'm only flying west coast I load US West.  If I'm flying from there to Texas I'll load US West and US Central.  Vector is it's own 'region' so I can just turn it on and off.  If I'm flying up high or near complex areas I'll usually leave it off.  If a region gets too big I just divide it into two (thinking about splitting Europe into East and West as well.

I too have a TON of things going on in the scenery.cfg and a ton of ORBX files.. This on a fast 4.7 6700 system with an SSD for everything.

 

**I saw it mentioned somewhere that if you create a junction point and move the ORBX folder elsewhere, that it can speed up loading time..

i'm not sure why this would be the case.. not sure if it was meant, move the folder outside the p3d folder but same drive, or move to a different drive?

 

I also use simstarter, but i use sceneryconfig editor to make the regions.. ie: NorthandSouthAmerica.. WesternUSAPlusCA only, EasternUSAPlusCA, USA only etc.. it helps slightly..

 

At any rate, Some case examples:

 

PAED FTX loading to runway with NorthAndSouthAmerica: 2min55sec (about 57 seconds to get past the splash screen) (for some reason PAED is a short loader compared to say KORS)..

 

KORS FTX loading to runway with NorthAndSouthAmerica: 4min55sec

 

KORS FTX loading to runway with WesternUSAPlusCAonly: 3min 37sec (about 1min 10 sec shorter going this route).

 

So worst case with all of north and south america, KORS may take as long as 5 mins, however, other areas (ftx ones included) might be shorter by a minute or more with this "fuller" test. Incidentally, these times are much shorter with SSD (in my case OS on one SSD, sim on another) than with a standard sata drive.. by as much as 5 minutes.. i had previously done some testing on the comparison.

I have Orbx moved to my HDD from my SSD and load times are the same.  with 6% pause.   I don't know about on same drive but outside P3D folder.  Don't think it would matter.

Fixed!!!

So since I updated P3D to the latest version, I had yet to take the time to install ALL of my ORBX stuff. I have LOTS... But with the new central making it so easy I thought I would give it a try. Well I am happy to report the long delays are gone, like completely gone...

Again I have ORBX global/vector/base/full fat regions and lots of smaller airports and all of them load in about 40 seconds. So anyone doing these crazy load this area or just that area to help load times improve, thats no longer necessary. I'm not sure if it was the file restructuring LM did a while back or what but glad its improved.

The regions also have airport files probably designed to help mesh better with their airports but also I'd bet a contributor to the longer load times.  My solution was to use Scenery Config Editor and only select the areas I'm flying in.  The Grouping system is a godsend, you can group airports, landclasses and meshes in a single group/area and select and deselect with a single click on a box. 

I have my sim on an HDD, but I've Symlinked Orbx, Scenery, Textures and SimObjects across two SSDs.  I was surprised to see the load performance was not dramatically improved.  Most of the loading isn't data transfer but processing.

All my FSX and ORBX stuff is on SSD and i also still get the 6% upon loading and a long wait time. I do have Simstarter NG, does disabling scenery that i don't use worth doing? Wondering if SSD use is really that more beneficial.

My crystal ball is telling me the 6% delay is where Prepar3d's figuring out the priorities and what to load and apparently it's doing it for the whole world since at this point anywhere is a possibility.  There's definitely a difference in load time enabling only scenery you need. I've also read someone once noticed Seattle terrain being referenced for load while flying in England.  If you have payware in SEA it would probably help not to have it loaded while flying in England although I doubt an airport would be loaded.  I have to wonder if this is just an optimization and that it only keeps one reference to a particular terrain texture and if both SEA and England are loaded it uses which ever had the higher priority, it's still the same terrain.

Once in the sim though it's surprising how little disk access there is.  I'm also running Diskeeper though with an 8Gb cache but I don't think that was the reason.  Terrain textures in general are fairly limited and repetitious with exception of payware airports, mesh and vector data.  I flew for hundreds of miles at low level at 500knts on the coast even where you'd think vector would be regularly hitting the disk and never saw a single disk hit.  It's possible that was due to diskeeper, would have to test that again to be sure, either way I eliminated disk access as a performance issue with that little test.

I believe the 6 percent point is where the underlying terrain mesh is accessed. Several years ago, I purchased the original version of Pilot's FS Global Ultimate mesh (worldwide). After it was installed, I immediately noted a much longer pause at 6 percent than prior to installing it.

I don't think that the sim actually LOADS all of the mesh for the entire world at that point - the total size of all the files would far exceed the system RAM capacity of a typical desktop PC, to say nothing of the 4GB process space available to a 32 bit program. Rather, it appears to be an indexing operation - where the sim (or Windows itself) has to to "touch" each file for future reference.

By the way, Pilot's said that they made some significant improvements in the way their mesh is accessed by the system in the latest version of Global Ultimate, and it appears to be true. I upgraded recently, and the pause at the 6 percent point is much shorter now.
