QOTS v3

[spil 2]

Good day all.

I want to present a problem I only have when flying the latest version of your great simulator.
My operating system:
Intel i7, 2.9 GHz
Windows 10, 64 bit
16 GB RAM
2 GB VRAM, 2 monitors
Active Sky 2016
FDC Live cockpit 2011

Scenery:
ORBX and some airports like ENGM, EKCH, ESGG, EDDF, KMIA, KLAX, KSFO.

No other software used and same configuration has been present now when I have perfomed test flights below.
Route I have been flying many times now is the same, only one way to make sure where and why it crashes.
ENGM - ESGG, very short flight but perfect for test flight.

Have tried many, many flights now with the QOTS v3. On approach or right after landing on the roll out the FSX crashes to desktop.
After a number of the exact same problems I reduced the graphic settings to absolute minimum with no effect. Same thing happens.
Then I change aircraft to your version of B738 NGX. No problems on the exact same route with maximum graphic settings. If works very well.
Just to be sure I have reduced the graphic settings so that also is the exact same in both aircraft models, no problem whatsoever in the B738 NGX.

This must mean that something very heavy for the system is going on in the 747, which I can understand, it is a lot of calculation and functions in this version, and I love it until it crashes.
But when I take a look at the specifications you should be able to fly it and I fullfill the requirements with my computer setting.

Next step is to test the QOTS v3 in Windows 7 Ultimate, which I had before I updated to Windows 10.
No problems at all, if flies very well and no crashes.

This must mean there is something in Windows that prevents QOTS to fly well in Windows 10, right?
Do you know what the causes can be?

When I look at the crsh reports I get some different from time to time, among these;
- StackHash_3e9b (PCH_03_FROM_KERNELBASE+0x0017A34D)
- Out of memory (also with minimum graphic settings)

I am not fond of disabling KB updates since they are for security reason. Some have found it a way to get around crashes but I have not tried that since many of the KB's are not present.
My update to Windows 10 was made in September this year.

Would really like to investigate and follow what is causing this problem.
Since I am a pilot in real life with experience of both aircraft models (B738 and B748) I must say, it is much easier to fly in real life than trying to get my computer to understand FSX :)
However I would like to follow up this problem and see if there will be an update for Windows 10 that solves this problem.

Do you have an idea why this happens and what the cause might be?

Thank you.

Also I experience FSX crashes immediately after the latest updates. 

A computer reboot fixed it, I think.

I use Windows 7...

Not sure, whether the forum can help here, rather a ticket at PMDG's .

You're running out of memory in the sim. Something is leaking, or you've stuffed too much scenery into the sim.

Is it possible that you’re running out of VRAM?

[downscc 1,327]

The OS is expected to make room in the VAS allocated to FSX for the additional video memory requirements if  it runs out of VRAM.  In otherwords, his exposure to OOM gets worse with only 2GB VRAM.

Two different problems, OOM and stackhash.  The OOM is easy to explain.  The stackhash indicates that something faulted but the OS doesn't know the faulting module so it is providing a hashcode for the stack to be used in debugging.  This is an indication of something like a video driver problem.  I've also had various addon dll modules cause stackhash events.  Happy hunting.

Hi
Thank you for responses.
It is strange that I get OOM even when video is set to FSX minimum in Windows 10, but it never tells me OOM in Windows 7 with exact same configuration.
That is why I wonder and keep investigating what is wrong with Win 10.

VR, well what I have read VR doesn't matter since FSX only uses the RAM.Right?

Well the hunt keeps on going. Sorry for late replies sometimes but usually I am up in the air :)

Not quite, all process by FSX is in the CPU but everything you see rendered is from video memory.  I don't think this is contributing to your low memory.

Keep in mind you only have 4Gb of VAS.  FSX will easily take 1Gb of it, and the B744 will take about 800Mb (0.8Gb), which leaves you less than 2.2GB for weather, traffic, scenery and anything else running in FSX.  It all has to fit in the same bag.  Perhaps FSX uses more in Win10 than Win7.  Get a copy of Process Explorer and investigate.

Eventually you will migrate to a 64b simulator...., there is much more than just memory issues to gain.

Good day all!

So now I have upgraded my graphics card to a ASUS 1060 Dual, 6 GB, OC.
Seconds after take off I get the annoying message from Windows "Your system has run out of memory" and FSX crashes to desktop.

So guys, it had nothing to do with the graphics card, that was a very expensive try.
Do you have any new suggestions?

The problem report I get now is this;

While staying on the ground everything worked smooth and nice. But how the h..l can I run out of memory with this configuration now?
What memory can it be? Windows 10 is a stupid version so far and does not tell much.

The problem report is the exact same as last time with my 2GB video card. So it cannot be the graphics card anymore.

Solutions anyone?

After upgrading your GPU, you absolutely need to ensure you have the correct drivers installed.

Moreover, I'm guessing you probably tried to bump up sliders, which could be the reason you're running our of memory.

Finally:

Well, all old drivers are gone, that was an AMD Radeon card.

No changes in video settings, they are still middle set for everything and even lowest possible.
Have tried the simulator tonight several times, with different settings, same route, trying to depart from ENGM with destination ESGG. Perfect short trip to test things, if the FSX would like to cooperate some day.

My lord, thank god its easier to fly the real B748 than in any flight simulator.

Any other suggestions?

Still my thought is that PMDG has put a lot of things not compatible with Windows 10 in their software but noone will admit that.
The exact same configuration in Windows 7 Ultimate, which I had before I was forced in to Win10, everything worked GREAT with the old video card. But as soon as Win10 came, all problems came.

There must be more than me having this problem, right?

[spil 2]

When I take a look at the FSX.cfg file I can still find this information;

[DISPLAY.Device.AMD Radeon HD 7700 Series.1]
Mode=1920x1080x32
AntiAlias=1

That was my old device AMD.
Is it possible to just remove this part of the config file?

I will NOT remove the FSX.cfg, it took me several days to get the simulator working again after I once did that before. There must be a way to modify display device without removing the entire file. Right?

[downscc 1,327]

Full names on all posts please.

You can rename fsx.cfg to fsx.cfg.old for the purpose of testing.

Before you got the new card I recommended you use Process Explorer to see how your VAS memory was doing during a session before doing anything else.  Investigate before you act.  You should be able to answer how much of the 4Gb limit you have is used for your FSX, PMDG and addons.  This has nothing to do with Win7 or Win10... you get 4GB.  Review the section on VAS in the Introduction document pg 26.

[spil 2]

And where is process explorer to be found for those who do not want to look the entire life for that?

Thank you in advance

[spil 2]

Also, it seems this problem ONLY happens when using the new B747 ver 3 from PMDG, it does not happen to any other aircraft.

[spil 2]

So now I do have that software as well. Guess that also takes power from a computer.

But okay. there is NO information about any VAS in that.What do YOU mean with VAS?

NO computer short names please, speak up and clear.
