VAS and OOM P3DV4

Recommended Posts

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.

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...

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

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 :smile:

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".

I thought I was doing the 1080ti but the price difference is still very high. Not taking advantage of the 4K for now I thought to choose the 1070 to save something. However, I think I can take advantage of the 1070 with the hardware I'm mounting. Ram DDR4 16GB 2400 and 2 SSD M.2 (1 250gb for OS and 1 1tb for P3DV4).

The 1080ti has also more memory and power which would allow you to launch PD3 with high resolution textures, more anti aliasing and other parameters that will give you very good sharp resolution results even when you are not running at 4k.

But if budget is a problem then I understand.

However, the 1070 should allow me to have good/excellent graphics performance, right? I would not regret the choice made of 1070... :blink:

I wouldn't worry about the 1070. 

Graphics memory use in P3dv4 will rarely exceed 6 Gb. That's VRAM as opposed to VAS.

As an example, I use a 1080 GTX with P3dv4. All graphics setting on max, 4096 resolution, Active Sky4, REX Soft Clouds/texture direct, Orbx scenery, Flight Beam airports, Ultimate Traffic Live, PMDG Queen of the Skies. I see a maximum of 5.5 GB Vram in use. Using GPUZ and the excellent EVGA monitoring software.

With current dx11 rendition in P3dv4, your graphics card will only use it's memory (VRam) to draw what's on your monitor. Those video games, using different rendering engines may use more VRam with all the 3d technology they use. We flight simmers don't use that tech (yet). 

With VAS in P3dv4 now only reliant upon how much physical memory you have installed, I doubt you will see any problems, provided you have the minimum RAM recommended by LM, that's 8 Gb.  

Cheers!

PD3V4 is very demanding, it depends of what you want to see, if you are looking to see things the same way as the promotional videos some developers show, then you need to have the hardware they have.

Ask people around to show you pics and videos with 1070 so you don't feel disappointed later as you would be aware of what your expectations would be.

I have a 980ti water-cooled with a I7 6600K over clocked at 4.6, but run my PD3V4 at lower resolution with mid settings so I can use dynamic lighting and my video card is running maxed out at 99 percent.

For the most part, I find with an I7-6700K and a 1070, the 6700K is ALWAYS my bottleneck. If you're running an 8700K, I would argue that you won't have nearly the cpu limitations that I experience, but will the 8700K be so much better that you'll end up bottlenecked by the 1070...with P3Dv4.1, I doubt it. You're right, a 1080Ti is terribly expensive. Will it give you an extra $300 - $400 in value over a 1070...I can't answer that, but as long as I'm running a 6700K, I will never buy a 1080Ti.

Best of luck whichever you choose.

You can set your PD3V4 with the TEXTURE_SIZE_EXP Tweak set at 10 and you would see how your video card would get maxed out!

No one "relies" on virtual memory. It just serves as a backstop so that OOMs don't occur. Apps begin to slow down indicating to thebuser to take action like saving files etc..

I never use any tweaks in P3d. Never see any need. The draw distance of distant scenery is fine with whatever I set in the graphics options.
