VAS and OOM P3DV4

[gianmarcoragazzoni 6]

Hi, being about to make the final transition to days on P3DV4 from FSX SE I wanted to ask you if I can forget the various issues of the VAS and OOM that were present on FSX with the new version of P3DV4.
Thank you.

Yes, you can forever forget about VAS and OOM in P3Dv4 due its 64bit nature.  Memory issues are forever gone.  Now other bugs will always creep up but OOM won't. 

Now you can fly a pmdg aircraft in Orbx full ftx regions with tons of payware addons on top and not have a VAS/OOM CTD.

But with everything cranked up expect a drop off in FPS so it isn't the rose garden you might believe it to be....

Apples to apples, it will be. Comprimises are necessary, as always.

Perfect, thanks. I hope I do not have big problems with the new i7-8700K hardware with the GTX 1070.

VAS and OOM gone! Great peace of mind  flying now with all addons payware to payware airports, ORBX etc.

You can even do two flights with PMDG 737 without restarting P3D V4.

Then you are lucky. If I do so, PMDG initializing is skipped and I get black gauges.

No problem on my end.

Have done several multilegs with different PMDGs, also with switching view inside/outside etc. as you like.

Never had any OOM since v4

Do you notice any fps drop when doing multileg in PMDG without restarting? It’s been such a habit it feels awkward to not restart. Paranoid... 

[guenseli 1,577]

No FPS drops on my side from multilegs.

If you are investing in hardware get a 1080ti instead, huge difference.

That seems a rather utopian view. Anecdotally, a significant factor in FSX's (and by extension P3D's) OOM issues is the program's inability to release memory when it is no longer needed, whether through design or through buggy code. The 32-bit architecture just meant you ran out of address space before you ran out of physical memory. If such problems remain (or are introduced by add-ons) the limit is now the amount of physical memory installed. If you reach that, expect exciting new kinds of problems

Assuming that one is not foolish enough to manually mess with automatic Windows paging file size, there is only one way that could happen.

If one's video card exhausts its onboard VRAM, it will then begin to use system RAM. If that gets used up an OOM will occur. That result can happen with both P3d and XP11.

If you are relying on virtual memory you don't have enough RAM. The System Requirements for P3D4 cite a minimum of 4GB but the recommended amount is 16GB. It will no doubt run with 2GB but not very well. Google "thrashing".
