Flying over London

Recommended Posts

I keep running out of virtual memory when flying over London with the PMDG. The FSX closes. Is there anything I can do to stop this happening? Can I alter the FSX config file to help the simulator continue to run.

I spent half an hour setting up the PMDG flight and the sim ran out of memory soon after takeoff over London, I lost all my FMC/Aircraft configuration.

What is the best way to not run out of virtual memory?

Most of the issues you've been posting about today can be resolved by reading the intro manual. Please do so. It'll save you a lot of time.

Switch to Prepar3d v4.

The only way to avoid an OOM is to lower sim settings, like traffic and autogen, as well as disable scenery that you are not using. It's a settings issue, not a PMDG issue.

I always saved my flights while enroute, not using FSUIPC but manually saving the flight using a saved flight names such as _ENR77X over and over for simplicity.  Save before takeoff, after TOC, every couple of hours and before TOD.  Use FSUIPC to monitor your VAS (how to do this is in the Introduction that Kyle pointed you towards).  If my VAS remaining was less than 800 MB at TOD then I would quit FSX, start a new session and load the flight I saved before TOD.  This usually adds back 800-1200 MB of VAS remaining.

Hi Dan,

Is there a reason you don't use FSUIPC to save your flights?  Just curious....

Thanks

Basically, I use FSUIPC sparingly.  The only use I have for it is to bind controller buttons to key commands for PMDG custom key commands and I will keep asking PMDG to add controller button/switch recognition to their custom command bindings.  That would eliminate any need for FSUIPC.  I have friends that use it extensively and would be lost without it and that is okay, I just happen to have little use for it. Why should I set up an autosave in FSUIPC, which causes rather long pauses when saving a PMDG aircraft, when I can do it myself from the menu?  It's not as though I have frequent crashes and a need to save flights every 60 sec or 60 min., if that were a concern I'd want to solve the problem of the crashing.  The only reason I save flights now is maybe I want a  do-over of a departure (always hand flown) or an arrival (sometimes not so pretty and I want to do over).

Thanks, Dan. Appreciate the answer.   I don't use it all that much but have the autosave feature set up.  I really haven't had to use it all that much, then again my flight sim hours recently have been so so dismal (a 3 year old and twins on the way have impacted one of my true passions).

I see a simple solution! Get your twins accustomed to falling asleep to the sound of jet engines, so that they will only fall and stay asleep if they hear them, and you’ve got a compelling reason to spend many, many hours simming!:biggrin:

Also, congratulations on having twins! Hope all goes well!

Wow, a toddler and twins on the way. I'm surprised you have any sim time.  The sound idea from John is a good one, we found our baby girl would fall asleep if we put her carrier on top of the running dryer.  You find ways to survive.

Isn't it worth trying DX10 preview mode as well, with or without Steve's fixer?

We don't support DX10 or the 'fixer' programs out there. So while that might work, there may be oddities that come out of it that we do not support.

It's worth the upgrade to P3Dv4 64bit. A bit of a financial hit, but you can take it one upgrade at a time.

Understood that PMDG do not support DX10 or the Fixer.

I can report I have both and they absolutely do work magnificently well with both my PMDG birds - 777 and 737 NGX - with no issues whatsoever.

Besides, DX10 with Steve's FIXER is the making of FSX for all flying activities.

I do not know Steve or work for him in any capacity. Just a happy customer.

DX10 did nothing for my system. If anything it made things worse. In my opinion switching to FSX-SE is the best cure for FSX problems. It runs smoothly and doesn’t need tweaking. Most importantly it fixed the memory leaks in FSX. I’ve never had an OOM using FSX-SE.

I guess that depends on how long of a flight you fly, as I've had FSX-SE go out of memory after 5.5 hours of flying. Of course, all the complex add-ons I have might do it.

Agree with Kevin on this one Kevin.  FSXSE has a few code fixes that the MS team had already completed but never got a chance to introduce in an update to FSX and this explains a few improvements.  It is still a 32b application and still subject to constraints and I've seen OOM while beta testing the 777.  One cannot appreciate how much more is possible in a 64b platform until you try it.

And I've done it. As soon as I got my new computer last week, I already had P3D V4 on it. With FSX, I would only be able to fly at most 5.5 hours before running out of memory, so that would be around 3 or 4 flights. When I tested P3D V4, I was able to fly 8 flights for a total of 12 hours. Whether it was a good idea is an entirely different story altogether, but I didn't run into any issues when I did it. This would have been with the PMDG Boeing 747-400 along with 8 different add-on airport sceneries.

This is the reason I went from FSX:SE to P3Dv4 never used the 32bit P3D but now I can and have added more scenery and airports, and can enjoy the PMDG 747 , 777 , without fear of VAS and OOM`s, and plan to add more.

It really is true what is often said; your milage may vary.

I did my Frankfurt - Tokyo flight in the 777F last year flying real time,  AS16, Track IR, sliders well to the right.

and that was over ten hours. No OOM. All in little old FSX sp2 with Acc. and DX10 Fixer with Cloud Shadows.

What is the best way to not run out of virtual memory?

What other addons are you using Nicholas?

Any UK2000 scenery, Orbx and the like?

London AND Heathrow are known hot spots for FSX/ P3D where your frames can drop horribly.

Minimise your sliders in settings and slowly work them back up until you reach a balance between aircraft operational capability (i.e; not a slide show) and surrounding scenery eye-candy. It's a compromise in this part of the World I'm afraid. Heathrow is my main VA airport so I fly out of there all the time.

If you haven't already seen this - take a look.

It's as good a guide as any on taking your first steps on the very long road of optimisation of FSX.
