Been wondering about this for a while so I thought I'd ask.  I have about 30 or so sceneries in P3D.  Most of them stay disabled (via SimStarter) since I only load them in smaller regional profiles....Eastern US, Central US, Western US, Europe, Pacific, Caribbean or New York City (yes, the city is in it's own little world)...wherever I'm flying, that's what's enabled.  But, I'm noticing that the more scenery I have the longer the splash screen stays up.  The load time is pretty descent once I select my aircraft and click OK.  I'm just wondering...is it scanning all that disabled scenery during the splash screen time?

I noticed this too and am wondering if PTA has something to do with it. Keep telling myself to try loading times with the default shader files but haven't yet. Maybe some setting(s) are out of range which causes P3D to have to rebuild the questionable file.

 

Might also be P3D phoning home for a license check on each load.

 

Speculation on my part.

 The amount of AI traffic you have often plays a larger role in this. The larger the number of aircraft.cfg's (as well as how many entries they have in them) that the sim has go through, the longer the time it will take to load on the initial launch. Scenery on the other hand doesn't have much effect unless it's the first time loading.

Using Procmon.exe (after disabling the GTN750 .dlls) I have a complete, line by line load of P3d....and you can too...no more guessing what is loaded when...set up different active and inactive scenery.cfg files thru SimStarter or the like....do the same with AI or any add-ones and answer your own question...

 

...just sayin...

This tends to be due to aircraft numbers. Mine takes ages since I started using loads of ai with my traffic installed. Scenery doesn't seem to make much difference.

Maybe it is the AI traffic.  I mean it's not a huge load time.  I was just thinking I didn't want it to get longer and longer.

I was always under the assumption that P3D was clearing shader cache while the splash screen was present.  The reason why I say this is that after the splashscreen disappears, and the scenario screen pops up, the default aircraft (f-35) appears slowly, rebuilding itself, as if P3D is starting "fresh", since the shader cache is now empty.  I could be wrong that it isn't the shader cache specifically, but something has been rebuilt prior to getting to the scenario screen.  Whatever is going on, i don't mind waiting if my sim isn't keeping latent things around from flight to flight that may cause the sim to get slow or crash later.

I got rid of MyTraffic 6 and splash loading times were cut in half, at least.

I find that rebooting my computer, which I don't do often, before starting P3D slows the splash screen loading time.

I would concur, but whether I do a reboot beforehand or not, my sim loads the same way.  I really don't pay any mind with it now, since it allows me to collect all my data and setup before my flight.

Yes, fresh first load is way longer. After you close the P3D and start it again, it will load much faster. I know this from FSX also.

I only notice it when I load up photoreal scenery, but I expect it.
