Hey Pilots,

Can't remember what last was installed on my Sim, but load time has increased significantly... (in excess of 3-4 minutes)...I mean flash page only. Once I choose vehicle, APT all good. Terrain loads blazing fast. Just initial load.I searched forums but nothing exactly the same. I believe last thing I installed  was CYUL but I don't think that has anything to do with it.

Any help would be greatly appreciated.

What version of P3D are you running?

There was a old longstanding FSX/ESP issue with the way library items were accessed/loaded that hugely increased load times, the issue is resolved in the current release (4.5.13).

Realtime amti-malware scanning can also have an effect because it will likely scan every file P3D touches as P3D loads.

3 to 4 minutes actually sounds pretty good.

As an example my P3D loads approx. 720 GB of data from an M2 drive and takes ~6 mins to display the scenario selection window, total time including the loading of an example scenario is ~9 minutes.

Cheers

I have latest version....This start happening recently.....It appears like I have installed scenery and needs to load every time I launch P3D.....shows on start "loading scenery indexes" every time.....but before that load time was less than 2 min.....not a big deal but....

Just to clarify, you are talking about P3D's startup time, right? You are NOT talking about loading of a flight? if I understood correctly, the loading of the P3D GUI is a process that includes P3D to go through all of your scenery as well as aircraft. So, if you installed some very larger scenery packages, that will almost certainly dramatically increase your startup times. Installing a lot of AI will also increase the startup time dramatically.

Try following a process of elimentation.

e.g. disable the recently installed scenery (one item at a time) and test the loading times.

Record the testing and date/times in a table for reference purposes.

You could also delete the Scenery indexes and allow them to regenerate.

When I strike an issue the first thing I trial is deleting the scnery indexes and shader files.

That's perfectly true. After installing last week all my AIG flightplans (about 270 flightplans, plus the AI models), the P3D start-up time (measured from clicking on its desktop icon to the initial scenario page where you select the airport, aircraft, time and season) increased by about 45-50 seconds. Currently, with all my AI and scenery addons installed, P3D starts-up in 2:40 minutes on my ASUS ROG gaming laptop, long enough for me, but it doesn't look so bad compared to others.

Hey Benjamin,

yes, only starting P3D, not a flight...Flight loads very fast. And yes, I do have huge amount of sceneries, For some reason I remember it was quicker before.....LOL

Thanks Rogen,

I haven't done that for quite sometime now.....I will do that once on the ground....

I used to be bellow 2 min or so once I click P3D Icon....now goes to close to 4-5 min for sure. Once I choose AC and Airport, launching flight takes less than 15 seconds....go figure.....AI I don't have just slight (few percent) P3D AI traffic....just not be alone....

+1 on the AI, large AI collections are the number one cause of increased initial load times, far worse than scenery.

Interesting, I had a feeling my load times had gotten longer, and it likely coincides with the advent of AIG-OCI and the vast increases in AI on my system compared to before.  Such is the price to pay for a great array of AI traffic I suppose.  I shudder to think how long my loads be if I hadn't switched to a SSD a few years ago (OCI folder is also on the same SSD as P3D).

 Without a doubt. When I configure my setup to load all of my AI aircraft (I have them split into regions for the Military AI etc), it's pushing almost 14 mins from an 860 Evo M2.

Well....that's long....I shouldn't complain then.

Same here. I also have installed and activated probably 1.6TB worth of scenery... hence my startup takes a while... I remember P3D when it was a fresh install, hehe. Took about 10 seconds.

Now I have to time it, my guess is 10 minutes.
