P3dv4.4 slow to start

Recommended Posts

Hi,

Just wondering if there may be a solution to this.

Since upgrading to 4.4 my start up time has massively increased in both getting to the selection screen and then loading to my start airport.This has increased by about 4 times.

I've not added any scenery and i've already tried deleting the shader and p3d.cfg files.

I've also upgraded my nvidia drivers to the latest version

I have most of the orbx regions and global textures and vector installed, but these were present in 4.3 also.

When i upgraded i did a new install but did not remove anything left after p3d had uninstalled.I then reinstalled p3d into the same directory so everything was in the same place prior to update

Any ideas as to why its much slower to load and any ideas on a fix

Thanks

FWIW, I think my boot time has decreased somewhat. It still takes several minutes, but I think it is down to around 8-9 minutes. With v4.3 I would have almost double the load time. However, once into the select screen and a scenario is chosen, the load up is as long as ever...the 6% stall and then incremental loading.

I have seen no real change in load times.  Load times depend on many factors, including whether a drive is fragmented which can happen after repeated P3D installs and uninstalls, especially if you get down to less than a third of hard drive space, even if you have more space free P3D can still get fragmented, even its default scenery.  I do not defragment too often, only if I notice a pronounced slowdown in starting times.  If my Win 10 boots in seconds I tend not to worry, and I have had Win 10 boot in seconds more often than not, as compared with older versions of Windows which used to boot painfully slow.

If anything, as compared to FSX on my older system which had less content than P3D, P3D even with photoscenery loads amazingly fast.  Xplane11, even faster although for some reason Xplane11 takes longer to shut down.  Different strokes for different folks, I guess.

Wow. 8-9 minutes and it was almost double that with 4.3?.  

I have noticed that 4.4 is taking longer to load then 4.3 did for me, contrary to what others are experiencing. I guess I should consider myself lucky, as it takes my system about  3 minutes, and I thought that was long.

You could try doing several things.

Load times are impacted by the number of aircraft (payware and AI) as well as the number of sceneries you have active. Given that few of us want to change those....

 

1. Delete your P3D Shaders folder (not the one in the main P3D folder).

2. Delete your Prepar3d.cfg file (which wasn't changed during the update to 4.4)

Both of the above will automatically be rebuilt for you.

 

Best wishes.

Perhaps you introduced some of the Prepar3d4.4 specific tweaks floating around, which may extend loading times seriously. Notably, TEXTURE_SIZE_EXP=10 would be a good candidate for this.

Dave's suggestion of deleting prepar3d.cfg would be a good test to see if it's the reason.

My loading time is roughly the same as before, but I used TEXTURE_SIZE_EXP=10 in 4.3 already most of the time. Loading takes several minutes when this is active, though (typically 5 min or so).

Kind regards, Michael

Since my first post in this thread a few days ago, I have had some key problems....the first I ran into were scenery spikes at and around CYKF. I have found no solution for this, including a reinstallation of the scenery and client elements. So, I am really going back to square one by deleting all three existing clients and then reinstalling the entire setup. I am not very happy about this, but it is what it is....and I hope it will be time well invested.

Along the way, and I do not know whether it is connected per se to the 4.4 installation, I have had dreadfully slow new installations of ORBX Vector and FTX Global. HD Trees, a much smaller file, went quickly and smoothly.   However, the long and slow installations of the larger file programs literally froze out other operations of my computer. As Doug Sawatzky noted over in an ORBX forum, this probably stems from a problem with my computer. I did a full hard drive error check as well as a memory check, and though errors were found on the drive which houses P3D, the W10 scan program corrected them.

I evidently will have to repeat that process when I finish with the fresh P3d 4.4 work. As I have often said about all of this, computering and flight sim are nothing but a giant variation of a Rubik's Cube...you just have to take some time and concentration to get everything in place.  🙂

I do not know anything about Orbx/FTX but doesn't the vector replace some of the scenery files?  If you reinstalled the P3Dv4.4 Scenery, the install might have written over the Orbx/FTX files.  I do know the Regions are standalone other than Orbx places several files in the Scenery/World/Scenery folder, mostly to adjust elevations.  You could have a mess.  I would follow the guidance from Poppet in the P3D Tricks, Tips, and How To's Forum - https://www.avsim.com/forums/topic/522254-ftx-orbx-scenery-prepar3d-updating-reinstalling-troubleshooting/.

I have few ideas about slow start and at the moment I myself was diagnosing load times as I write this post.

1) Mesh does take time to load - for example on my system

All US FTX Regions + US FTX Airports & Global + Vector Only the only addons - Load time start is about 20 Seconds to Scenario screen.

2) Add FreeMeshX USA Beta (50GBs) - Load time goes to 31 Seconds to Scenario screen at bootup.

Please run Lorby Freeware Addon Tool for Prepar3d (this is a critical app to have with Prepar3d v4) - Go to Tools sections <-- click on the right arrow and go to tools

Here click on check encoding.  This option will tell you if any off the new XML files have wrong encoding.  

The wrong encoding slows the boot of prepar3d down.

If there are errors

Download Notepad++ (it is free and opensource).  Once the file is opened in it - All you have to do is click on Encoding --> Encode in UCS-2 LE BOM and save the file.  

Rerun Lorby's tool and go to tools again - check the encoding.  It should say no files have errors.

Try the sim.

If you have any addons which use SODE - make sure your sim is registered on it - Click Register Sim in the SODE app.

I hope these suggestions can help you out

Since I started this topic and reading some other peoples start times,its seems mine was of a similar sort of start time.

Due to a few other issues that kind of annoyed me a bit, i decided to wipe everything and restart it from scratch. Although i'm still adding the last few airports the startup time has reduced by a few minutes, so overall  its been worth the time restarting from scratch and the other issues have also gone

Two things that affect load times. Active Scenery and no. of aircraft.
