This is a bug in Flight Simulator that has been there since the beginning, and I'm not sure even Pete Dowson could offer a workaround.

 

It isn't a "bug" - it's a mathematical limitation of what you can do within a 32-bit address space. There is no possible solution other than someone getting the FSX source and modifying and compiling it for 64-bit. All the addons that are code-based would also have to be recompiled and made compatible too. When FSX came out, PCs had what, 2GB of RAM and 128 or 256MB of video RAM? I doubt FSX's designers ever foresaw addons that could actually saturate the 4GB VAS completely.

I meant the wife thing...... er..... but maybe recompiling FSX to 64-bit WOULD cure the wife-interrupting-takeoff-and-landing issue, I'm thinking?!  That would be great!

 

It's a bug I've had to cope with for 24 years!   I've tried buying bigger houses but the VAS limit still remains a constraint even so.....  I suspect the interrupt generation is organic in some fashion.  Too much multitasking.

Consider yourself lucky, some of us have had to have that coping skill for beyond the 40 year mark....and yet would still not trade the issue for anything... :ph34r:  . :lol:  . :wub:  . Only one thing to do and that is learn to cope......either with the OOM issue in FSX, (because it is definitely not going away) -or- with the runway-interruptus on takeoff and landing (and I surely do not want this to go away). B) . :lol: .

My first flight simulator had to work with 48 K(!)B of RAM. (ALL data in - there was NO additional data stored on my ... tape recorder.)

 

 

Today I have 16 GB - and despite the 4 GB VAS limitation it takes me a looong way towards a fine simulation.

 

 

I once tried the 'set no_of_wives back to zero' tweak - and it has been working for me for 9 years by now. (Not easily recommended to fellow simmers, though.)

Hello Ryan,

First I want to say that my FSX is still working perfectly. The settings you did make very little difference in FSX, visually, yet allow FSX to run fantastic.

Believe it or not, I am running 100% AI now, using MyTraffic. I can't believe it myself.

I actually flew into FSDT Vancouver CYVR last night with 100% AI. There were so many AI aircraft that they were sitting on top of each other in the gates (I will be turning it down a little).

Before I couldn't even fly into CYVR without an OOM. I purchased it, but had never seen it. Now I can fly in with 100%AI!

 

I was wondering. Considering that FSX is only 32bit, and that could never change.

Would it be possible for developers to make products that have most of their build outside of FSX, so that much of the heavy calculation would be done in modern programs running independently and developed specifically for their product, but connected to FSX so that just the graphics would be loading the 32bit program down? All of the heavy calculations would be done in outside programs made by the developer, to take all of this load off of FSX and allow better graphic settings.

I believe Majestic did something like this with their Q400, which has the FDE running outside of FSX.

This cannot be done. PMDG were one of the first companies to pioneer taking processes out of FSX systems years ago very much like Majestic are doing today. So this has already been done.

 

Even if you do it externally the external program is still limited to being 32bit as it is interfacing with FSX - there was a discussion on this recently. Doing the process externally does allow you to get away from some of FSX bugs in terms of realism but not from its 32-bitness. Ill try to find the thread now.
