Well, I have just completed my first OOM test flight at UK2000 London Heathrow Xtreme (in DX9 mode), and the results are rather significant. I disabled ALL AI planes (UT2 and FSX), but kept all of my scenery detail sliders at maximum, and activated UK2000 Heathrow Xtreme (GO Xtreme detail level), Gatwick Xtreme (GO Xtreme detail level), London City Xtreme, Stansted Xtreme, VFR London X (with Very Dense and Extremely Dense scenery BGLs removed), VFR Airfields Volume 1, FSX Power Project (pylon network and wind turbines), ES Treescapes Autogen at Extremely Dense, and REX Essential clouds (Medium Density, scattered 3/8, and 1024x1024 resolution textures) and water (advanced animation "white caps" and 1024x1024 textures) active.

 

I started at a Heathrow parking spot, taxiied to the runway (following ATC instructions), departed straight out, contacted Heathrow Approach when requested, turned left 180 degrees, proceeded downwind, turned 180 degrees again, commenced final approach, landed, and taxiied to the gate instructed by ATC.

 

No OOM errors.

 

A very interesting result. It shows that the scenery packages themselves do not cause the problem. It must be the excessive number of AI planes that I normally have flying around. My next test will increase the UT2 and FSX AI to 20%. I will let you know what happens.

Or, the combination of items you selected for this test just coincidentally did not get you to the 4G limit. Adding AI may finally push you above that but it doesn't mean that AI itself is the culprit. If you could add yet another scenery package(not sure that's possible since you already have every one there is almost) and not add any AI you might cross the threshold too.

Kevin has a point. Perhaps you are able to trade one detailed airport for AI and so on. Well, guessing of mine.

 

Either way, since testing can be tiresome, good hunting! Looking forward to the results. :smile:

A poor choice of words on my part. What I should have said is that this test clearly demonstrates that the combination of detailed "London area" scenery packages that I have installed on my PC can actually live and work together without causing OOM errors. I just have to work out what level of AI activity I can add to the mix without taking the entire system "over the edge". As soon as I experience an OOM error, I will test the same percentage of AI planes with one of the detailed Xtreme airports mentioned above deactivated, and see if it makes a significant difference.

I'd also suggest that to give you a bit more quantitative data (more than just pass/fail) you might want to use process monitor in conjunction with your tests. Then you'll have a better idea of how close you're actually coming to the limit as you add things back in, and how much each change is responsible for getting you close.

You don't mention what aircraft you were flying --- Let me guess The NGX. The NGX is the most VAS resource intensive addon there is for FSX, because of the detail PMDG put into her! With the combination heavy AI, and detailed scenery it wouldn't take much to push FSX over the edge. It does on my system. I solved it by not loading unnecessary addon dll's upfront (From the DLL.xml file). I set all my optional DLL's (Mostly the aircraft addons) to manual load. Then I only load the dll's required for the flight I'm flying. (Ex: No need to load CS DLL's if I'm flying the PMDG NGX) Since then I haven't gotten any OOM's, unless I load additional DLL's. Example yesterday was the first time I've gotten a OOM since doing this, but I tried to use AccuFeel with the NGX which was additional DLL's. With any other aircraft, I don't have to do this, but I do anyway because I find FSX runs smoother that way. This all on a Vista 32Bit system, which is even more restrictive as far as VAS goes, then win 7/8 64 bit.

Yes, high AI amount can definitely trigger OOMs easily. I have witnessed this often. Ideal Flight 10 has a great feature which can fully, like totally full, force populate any airport and result in FSX being pushed too far. I have learned to lower the setting at busy airports rather quickly.

 

I wish there was a program that can densely populate an airport with basic, static, very low memory requirement planes. So we could have a nice busy looking airport but not have the crashes that go with it.

 

FWIW, seems that the freeware version of FSUIPC4 contains some sort of automatic warning function that starts a Windows type chime when FSX is very near the 4Gig virtual limit. Took me weeks to figure this chime out!!!!!!

Ya, AI is the culprit 100%.

 

For me, I have my ai traffic at 17%. 17% seems to present the best setting for this. Not too many aircraft holding you up from taking off, but you still see them at the gate when taxiing, and in the air occaisionally.

 

-btw I have Mytraffic 2013 installed.

Don't want to hi-jack the thread, but could you possibly explain how to selectively load DLLs? Thanks

 

EDIT: Did some investigation, Will changing this line to True do this?....<Launch.ManualLoad>False</Launch.ManualLoad>

Your FSX.cfg file will have a section for Trusted items to preload into FSX. Remember the dialog box that would pop-up and ask if you want to load and save the answer? Remove those trusted lines from FSX.cfg and you will be asked again if you want the DLL to run or not. You can say Yes or No. If you say Yes you will be asked if you want to save as a Trusted item. Then you would say No.

 

The drawback to this? A whole lot of Yes or No every time you start FSX, depending upon how many DLLs want to run.

YES... it will.

Yes that's the way you do it!!

WOW, that was quick!! THANKS

^This...

 

I can run max AI but with lower settings and not run into max VAS.... AI may be a contributing factor but it's not the only factor.

Second test complete.....and it was a FAIL. The aircraft that I am flying is the Quality Wings Avro RJ70, and the AI settings were as follows......

 

UT2 Airliners: 20%

UT2 GA: 0%

FSX Airliners: 20%

FSX GA: 5%

 

The ironic part is that, even though the UT2 GA is set to 0%, this still amounts to over 21000 flights if the "Display" checkbox is ticked! This is enough to add quite a few default Learjets and KingAirs at Heathrow and elsewhere, so I will see what happens with the above settings, but with these aircraft disabled.
