VAS usage with XP11?

Recommended Posts

Curious if anyone has been monitoring VAS with XP11 with some "moderate" addons running?

 

I believe in one case I spotted online, through using process explorer it appeared that with NYCX at least, memory usage was approaching 15GB..

 

In my system i currently have 16GB of memory.. contemplating adding 16GB more.. perhaps its just a no brainer, or maybe the one test was a fluke.

 

Curious overall what everyone is finding... i hope to do some testing this weekend on my own system.

Nowhere near that.  At high settings with HD mesh, etc., I'm seeing < 8 GB.  Maybe NYCX is unsual though.

:Shame On You: please don't use the word VAS, it reminds me of the dark moments I had with the other sim... :P

 

Joke aside, I've never seen mine go beyond 12gb with all the goodies out there including UHD mesh

Well, I only have 12GB at present and XP11 quits multiple times when I fly over LFPG or hopping more than a few airports in one session. So it can definitely bust 12GB of memory. 

 

I don't blame XP11 though at all and I'm happy to see it uses my memory to the fullest. I'll build a new PC soon and 32GB will be mandatory, with option to expand to 64GB.

Like others, I haven't seen going beyond 12GB (uhd, orthos, payware, etc).

I also have 16GB of RAM, hopefully that should be enough :)

X-Plane hardly even needs VAS, it directly addresses any and all available RAM since it's 64-bit. Plus, all of those airport scenery packs—they technically use up VRAM (textures, shadow rendering, etc), not RAM. It's mainly the meshes, and aeroplane add-ons that go into RAM. And complicated meshes jack up the RAM usage.

XP usually sits around 15-16GB RAM usage for me and well over 5.5-6GB of VRAM. I have seen it hit into the high 20's but that is rare. X-CSL will hog a ton of memory at higher resolution settings with XSB. I actually had numerous OOMs because of this until I figured out what was the cause.

if your pc can handle uhd mesh then more than 16 is always a good idea.

 

The problem is not always x-plane. the problem is what do you do besides x-plane. Just with x-plane you might be fine, but then you have firefox open with 2-3 tabs of your navigraph charts, you have plan-g open, maybe even youtube or other entertainment forms during cruise, and voila another 4 gigs of ram used without x-plane.

 

Personally i upgraded to 32gigs and with the current prices of sub 100€ for even ddr4 its a pretty no brainer.

NYC X is extreme.  I have tested with HD Mesh version 3 and default cities and larger airports with things like Pilot2ATC and XEnviro running.  I have never had more than 8 GB VAS usage, and usually more like 6 GB or less.  I do, however, get to 7 GB VRAM use in 4k.

As said before, X-Plane 64bit doesn't use VAS (Virtual Address Space). It uses RAM, and VRAM. That's all. I think it's important to use the right terminology, VAS is a thing of the past and operating systems and software will rapidly obsolete the 32bits memory addressing.

 

cheers,

I agree about the VAS terminology. It refers to a fixed 4GB address space in another sim, and doesn't have anything to do with the way X-Plane works.

Well, to be precise: VAS is active and works with 64 bit programs, but outside of the 32 bit area it doesn´t contain any usefull user information.  In 64 bits its limit is now 128 TB.
