Well.  After doing some extensive testing (still not done).  I have thrashed my SSD so many times, that it is sad.  I hope one of these days Rob or Simbol can get me into the LM P3d Beta team.  

I installed only Orbx Socal (left all SoCal settings to default), installed Orbx KAVX, RealAir Duke, LatinVFR KSNA, F1 GTN, and flew from KAVX to KSNA - this time no gpu load happened, and the KSNA scenery showed up as it should (slight slow loading, that is due to default medium autogen distance) but no pauses!!!

I am going to install NorCal and see what happens on the same route.

I have a feeling that all of this could be caused if Vector is installed or If too many things are installed P3D starts to hang, unless there is some limit on the scenery.cfg plus addons installed at once.

I think this is the general consensus that less is more.  And in my opinion I point to Vector as being the biggest culprit in causing the pauses but not all of them.  Josh

Just returning to this thread as I haven't been using my simulator in many weeks.  As Orbx extended their sale by a further 24 hours I decided to purchase True Earth Netherlands for about £15 which is a bargain.  I cannot see me investing in other TE regions as the sheer storage space required is enormous and the only feasible way to install them is on the old mechanical hard drives which to me is a step backwards.  Orbx is getting a lot of the blame for these Long Pauses, I know I got them simply by installing and having only their full fat regions and global products installed and nothing else.  Long pauses occured regardless of the sims settings, even with every slider to the left...the sim looked so ugly but still paused for up to 8 seconds at set test locations. It also happened when I formatted my system and installed Windows 7 as test when I thought something had messed up Windows 10, I'm back on W10 but the issue is exactly the same. 

True Earth has got me thinking about the future of Prepar3D and the direction ORBX are taking.  We already have a messed up sim which simply cannot cope properly with too many add on sceneries.  It is indexing the active scenery library when you cross certain lines when flying over scenery and causing lengthy pauses from 1 - 8 seconds (these are not stutters).  Orbx's full fat regions are huge compared to many other scenery packages from other companies so what impact will True Earth have on long pauses?  I am currently downloading a 72GB zip file to install tomorrow, I can only imagine it will make the pause problem worse and with more TE packages in development the landclass method maybe a thing of the past.

Any thoughts?  Has anyone with a large amount of other sceneries carried out tests with no Orbx scenery installed or active to see if the indexing problem still exists?

You may be in for a pleasant surprise.. TE Netherlands does not cause pauses on my system, unlike FTX SoCal for example. 

Just a guess, but there are a lot of airports in the L.A. area.. by comparison, NL has very few airports..

Download “ultimate windows tweaker tool”

 

 

under performance; turn off prefetch and super fetch.

 

this worked for me and it correlates with a previous post or two that I’ve seen referencing “indexing” in the background. 

This worked for me.  Give it a try and let’s see if this could be a common denominator

In Windows 7 , I only find Superfetch, no Prefetch.. is that a Windows 10 feature?

BTW, Services can be turned off in Windows Control Panel..

I'm puzzled how this works to stop long pauses because it's the SIM requesting the active scenery library be scanned rather than something Windows is doing. I'll give it a shot though my long pause locations have moved since v4.4 They were in a few repeatable locations where the SIM would completely stop for at least 8 seconds if I had all my scenery active. Same occured even with every setting on Mon or switched off. I since started using a scenery configuration editor.

Will do no harm testing this I guess

Just tested it and saw no impact on "long pauses".

The long pauses are an Orbx / P3D thing..

V4.5. initially eliminated a lot of it, but the Hotfix brought it back, at least partially.

Clearly LM is aware, but performance trade-offs were made to please the largest number of users..

True Earh NL over Amsterdam with FlyTampa Amsterdam Schiphol ,Real Weather and PSXT Live AI Traffic was very demanding on my system. Then I decided to built a second view pc and now I am quiet happy with it,

Recorded with a cellphone : just after takeoff from Amsterdam Schiphol rw 36L and a turn over Amsterdam. 

AG both very dense.

Thank for posting Darryl!

I only found Prefetch, No Superfetch on my up to date version of Win 10.

The good news after disabling Prefetch is the mico stutters are now gone.
But as others noted the longer pauses (.5 to 3 seconds) still exist esp in highly complex Orbx environments. 

It'll be interesting to see if TrueEarth for P3D addresses/corrects this.

Cheers all,
D-Man

 

On the latest versions of Windows "Superfetch" is now combined with "SysMain".  Simply disable "SysMain" in Services as described previously for SuperFetch.

My understanding is that "SuperFetch" was not recommended for SSD hard drives (and was supposedly disabled automatically by Windows in that event). The issue is that it would prematurely wear down an SSD with too many write operations. So the marginal benefit was not worth it.

I use SSDs in my multi-computer setup.  I have been plagued recently with slow scenery loading arriving at destination airports, including pauses etc. as described by many here. I found that SysMain was in fact running, and I have disabled it.  However I have not really seen an appreciable improvement....maybe slightly, but too close to call.

Me too. Disabled Superfetch/SysMain and the normal Prefetch. No noticeable changes whatsoever.

Big pauses here (about 5 seconds or more, occasionally less) whenever the aircraft gets closer to an addon airport scenery, apparently the simulator simply doesn't multitask with a loading addon airport, don't you think?

What exactly are we disabling here? Are those "fetch" things important for something else in Windows?

Edit: I just Googled it.. all clear now.
