if i can make a suggestion regarding loading times:

I have monitored the CPU usaged on loading and it looks like P3Dv5 is not using the full potential of multithreading here.

I was able to reduce loading times of SimObjects in our AI Manager tool to just some seconds using multithreading:

Code: Select all

16.05.2020 15:27:25 - Collect SimObjects from: 21 paths
16.05.2020 15:28:37 - Collected SimObjects: 434
16.05.2020 15:28:37 - Collected SimObjects from: 21 paths

Where do I put that code please Kai?

LM can this please be fixed?

In previous versions the Select Vehicle UI, entering multiplayer and SimDirector, and a few other various cases would cause long loads due to populating entity lists. We moved this to startup and also cache this list to improve the speed of accessing these parts of the system. Large numbers of AI could be impacting this initial load. We'll investigate this more on our end.

Ah! This answers one of the questions I posted here. I have a large hangar (not to be read in a music-hall voice) of something like 500 aircraft. It's a main part of the fascination of the sim for me. I have long found this to be unworkable in practice so have for some time been storing all aircraft in an external "hangar" folder and simply moving the ones I want to use in a session across to simobjects\airplanes or rotorcraft. The nice thing about this is that you can (could) simply pause the sim, switch to a file manager window, and then move additional aircraft in to simobjects and they would be available when you went back in to the sim. This of course no longer works in the new environment, and requires a restart of the sim. Which in turn takes longer.

A suggestion. How about making this caching and list population switchable? A simple "EntityCache [0/1]" in the prepar3d.cfg file could be defaulted to on (or omitted by default) for those with small lists/no AI/no inclination to fiddle, but allow the rest of us the freedom to revert back to the old technique.

Generally, the improvements from DX12 are better than the new problems, and I've no doubt it will all settle down in time, but I don't think this new feature is an improvement, by any means.

Hi Everyone,

We'll have this improved in the next hotfix. Thanks again for the reports and for your patience while we work this.

Regards,
Rob McCarthy

thanks for fixing, will report back when the next hotfix is out.

If a further hotfix is planned for v. 4.5, it would be very nice if a similar solution could be incorporated in that.

Great news ! You make my day.

I installed Windows 10 2004 over the weekend and surprise, surprise, not only having almost one GB more VRAM available, also the loading time of v5 almost halfed. Just that you know this...

Hi All,

using IVAO MTLs it takes more than 8minutes on my system (Using Samsung SATA SSDs)....
very very long time, it would be welcomed if LM fixed it or created setup option to affect this loading process.

Thanks,

Rado

thanks for the fixes in HF2 :) major improvement from more then 10mins down to less then 2mins - great work
